Portable power stations can deliver power when you need it most, whether during power outages or just for an off-grid adventure. These handy electricity suppliers vary in size, output, and energy source, not to mention durability. That’s why we’ve tested 18 models since 2022; some we’ve kept on this list, while others have been replaced by newer power stations that we like even better. We spent hours testing some of the smaller models and days with some of the larger ones. We even took some road trips to baseball tournaments and other events.

The Goal Zero Yeti 1500X Portable Power Station (updated model from the 1000X we tested) remains our favorite thanks to its ample power and potential to supply even more backup power by connecting additional Yeti batteries. Not only can it power tablets, phones, and flashlights, but it also powers appliances and power tools.

It’s not the only great option, however. All of the following options make great picks for an emergency power station—in case the power goes out—or portable energy supply.

Craftsman blends affordability with portability and sprinkles a bit of capability on top with its 150-watt power inverter. This budget-minded model snaps onto any 20-volt battery from Craftsman, turning it into a compact power supply that you can take anywhere or store in a tool box. 

This power inverter features three ports: a USB-A, a USB-C, and a standard AC outlet. It also has a built-in work light to illuminate work or a path back to the truck. Runtime will be determined by the size of the battery it’s on, but with a 150-watt output, it can handle lamps, cell phones, and other devices. 

In our opinion, this affordable little inverter is ideal for the jobsite. It can quickly turn any 20-volt Craftsman battery into a power station, allowing folks to charge their phones, power drop lights, or even charge a laptop when there isn’t a battery source nearby. Is it full of possibilities? Not quite, as it’s limited to the battery it’s attached to, but we think anyone with Craftsman batteries ought to consider adding it to their tool box for its convenience and affordability. 

Get the Craftsman portable power station at Lowe’s, Ace Hardware, or Walmart.

Upgrade Pick

EcoFlow Delta 2 Max Portable Power Station

What We Don’t Like

• No 30-amp outlet to run an RV
• The heaviest model we tested

During testing, we were impressed with the performance and huge array of output options on the EcoFlow Delta 2 Max. With a total of 15 outlets/ports and 2,400 running watts of power, we found it to be the most rugged and versatile option in our lineup. While some power stations on our list are better for shorter and less demanding circumstances, this beast from EcoFlow can power a full-size refrigerator for up to 14 hours. 

This EcoFlow power station uses an LFP (or LiFePO4) battery, which has nearly twice the expected lifespan of traditional lithium-ion batteries. It charges via wall outlet, 12-volt car outlet, or solar panels. Its large display is easy to read and clearly displays output and expected runtime based on current usage. Though we think this unit provides an excellent value, it is the heaviest power station we tested. It also doesn’t have a 30-amp outlet to power an RV.  (If that’s something you’re after, check out our Jackery solar generator review.)

The Delta 2 Max has the highest price tag in our lineup, but if you’re looking for convenience and reliable backup power, it’s worth the money. For even more power and versatility, you can add one or two extra Delta Max smart batteries at 2,016 kilowatt hours each, for a maximum total storage capacity of 6,080 kilowatt hours.

Folks who’d prefer to take their power off-grid or simply like the idea of a reusable, portable power source will want to consider the Jackery Explorer 1000 portable power station. This power station is compatible with solar panels and will recharge in about 6 hours with two 100-watt panels in full sun.

The Explorer 1000 features 2,000 surge watts with a 1,000-watt continuous output and a 1,002-watt-hour capacity. It has three standard outlets as well as one DC, two USB-A, and two USB-C ports. The digital display keeps you up-to-date on the Explorer’s battery percentage, output, and input. And if the power goes out in the middle of the night, the Explorer 1000 has a built-in flashlight to guide the way.

This solar battery was truly one of our favorite models in the test. We’ve been using this model for over a year now, and our test unit came with two solar panels that are easy to set up and plug into the power station. Also, the Jackery Explorer lasted the longest of all the models in our air conditioner test, and that’s truly saying something considering it’s been drained and recharged a few times in the past. But, beyond the solar panels and capacity, the Jackery is very easy to use, and the digital display is clean and simple to read. Just keep in mind that solar panels can be expensive if purchased separately.

Product Specs 

• Power output: 2,600 watts
• Battery capacity: 1,024 watt-hours
• Dimensions: 9.1 inches high by 17.6 inches wide by 8.9 inches deep
• Weight: 28.7 pounds
• Outlets/ports: 2 AC, 2 USB-A, 2 USB-C, 2 SDC
• Charging source: Included AC adaptor, included SDC car adaptor, solar

What We Like

• Portable kit includes weatherproof cover/carrier and 100-watt solar panel
• LFP battery maintains 70 percent capacity after 4,000 charge cycles
• Accepts up to 6 solar panels and 800 watts of solar input for charging
• Convenient for car camping, tailgating, and other remote power needs

What We Don’t Like

• Not enough power for an RV
• The solar panel will not provide reliable charging when it rains, or if the site is heavily shaded.

If you’re planning for a camping trip but don’t want to completely rough it, then a portable power station can help. The DJI Power 1000 stores 1,024 watt-hours of electricity and produces 2,600 running watts and up to 4,400 surge watts. That is plenty of energy to keep the lights on at night, charge an array of electronic devices, and power a few small appliances. Not only that, but this kit also includes a weatherproof carry case to protect the unit from rain and a 100-watt solar panel to take advantage of nature’s free energy.

We loved the easy versatility of the DJI Power 1000 for on-the-go electrical needs. It charged fast when plugged into a wall outlet—just over an hour to go from under 10 percent to full charge. With one 100-watt solar panel, it took about 8 to 10 hours to recharge. It’s important to note that we lucked out with clear sunny weather and made sure to redirect the panel every couple of hours for maximum sun exposure. In low light conditions, we would expect a much slower charge.

This unit was small enough to fit in with the rest of our gear, and it held more than enough electricity to run our LED string lights for 6 hours, brew four pots of coffee, and recharge two phones and a weather radio on a weekend camping trip. The large LCD display provided an uncluttered real-time status report while charging or using power.

What We Don’t Like

• Bulky and heavy, limited portability
• May not handle HVAC surge watts

Whole-home backup power is an area where portable power stations have lagged, but the Anker Solix F3800 bridges the gap. This powerful and portable unit boasts a whopping 6,000 running watts; 9,000 surge watts; and 3,840 watt-hours in its base configuration, with options for expandability up to 26,880 watt-hours. That’s enough to keep the refrigerator, deep freezer, and key household outlets operational through an extended power outage. 

The F3800 is unique, not only in size of its battery reserves but also in that it is equipped with a 120/240-volt NEMA 14-50 outlet that can be directly connected to an electrical subpanel. It also features a NEMA L14-30 outlet that can directly power an RV for a weekend getaway. Make no mistake: This amount of battery storage is larger and heavier than the other models we tested, but an extendable handle, two 4-inch rollers, and two 2-inch locking casters make it easier to transport.

For our test, the F3800 powered a window air conditioner, a full-size refrigerator, a microwave, three table lamps, a Wi-Fi router, and a television. When the refrigerator or air conditioner entered the active cooling cycle, the surge did not affect the other devices. We ran everything this way for 2 hours, and it worked perfectly. Plugged into a wall outlet, the unit fully recharged from 15 percent in less than 2.5 hours.

Our limited test showcased the remarkable ability of the base setup, but it barely scratched the surface of what an expanded Anker Solix system could accomplish. As with some other portable power stations, two F3800s can be paired to deliver 12,000 watts of power. Adding up to 6 expansion batteries per power station boosts storage capacity to as much as 53,800 kWh in a dual F3800 system. Each power station is capable of accepting up to 2,400 input watts from solar panels to recharge and further extend runtime.

Bringing essentially a box of electricity anywhere always has its risks, but knowing that the River 2 Pro is certified by one of the most stringent vehicle agencies in the world offers a big boost in confidence. We liked that this device fits in the back of a quad-cab pickup and provides plenty of power for all of the devices a family can run on a road trip, such as a laptop and several personal devices. We did think that the display might be slightly off of calibration on our unit. It didn’t register any output while using our test heater’s low and medium fan settings. However, we don’t see any other mentions of this type of thing in online reviews, and it wouldn’t be an issue when plugged into a vehicle on a road trip.

For a portable power station that can withstand the outdoors, emergencies, and likely more, the Vtoman power station is a great option. At a hefty 37.4 pounds, it’s designed to be stackable, either to add an extra battery or when you have a lot to fit in the back of your car or truck. Its marketing materials claim that it can hold up to 60 pounds stacked on top. We tested that claim—and it held true. We stacked 60 pounds of hand weights while we charged devices, and kept them there for more than 2 hours. When we pulled the weights off, we didn’t see any dents, cracks, or even bowing.

The Vtoman also lived up to its charging claim—that it charges from 0 to 100 percent in 70 minutes. Our experience was nearly spot on to this claim (about 72 minutes). Overall, its power seemed to be on par for its capacity, and we were impressed. We ran a vacuum that pulled an average of about 620 watts on a 94 percent charge for nearly 71 minutes. We also used the power station to charge phones, laptops, and run a pedestal fan for more than 6 hours. Plus, we appreciated the extra features like cord storage and an LED light with five settings. Those make an already great product even better.

How We Tested the Best Portable Power Stations

We wanted to ensure that we were only suggesting the best power station for each award. We developed a series of tests and trials to put these power stations through, taking note of their performance at each step. 

We used the smaller power stations to charge devices like our phones and laptops, paying close attention to how quickly they drained relative to the speed at which the devices filled. We also ran a desk fan and a lamp off of each model (separately, as they each only had one standard outlet). We compared these models based on size and portability, ranking them by weight and size.

The tests were quite different for the larger models. The timing of this test was good, since the transformer at the end of the street blew five times within 2 weeks after receiving the models. They all saw work as an emergency power station, keeping refrigerators, TVs, routers, lights, and household devices up and running. 

We also tested the larger models with the most power-hungry appliances we could think of: an air conditioner and a space heater. We waited for a 90 degree Fahrenheit day and cranked our window air conditioner to its coldest temperature setting and highest fan setting. We then did the same for the space heater (talk about energy consumption). We noted how quickly each model drained and which models (there was just one, but we mentioned it below) weren’t able to handle the compressor kicking on.

The results of all these tests gave us the background we needed. We could assemble a list of the best power stations, giving each model that passed an award based on its strengths. 

What to Consider When Choosing a Portable Power Station

Keep these important factors and product features in mind when shopping for the best portable power station to keep devices charged or run appliances when the power goes out (or when you’re off-grid). Note that while power stations and generators are different types of power sources, the terms are often used interchangeably. See the FAQ below for key differences.

Types of Portable Power Stations

The top portable power stations, also often called portable power generators, fall into two broad categories based on the method they use to collect and store energy: electric and solar. Many times, solar portable power stations are also rechargeable via AC power, serving as a rechargeable generator of sorts.

Electric

Electric power stations, also known as portable electric generators, operate like a large battery. Simply plug the portable power station into a wall outlet and it charges quickly. Some power stations may also charge in a car power outlet, provided they have the correct adapter, but this takes longer than it does in a standard outlet.

These models work best for indoor purposes and devices with low power requirements, such as cell phones or flashlights. Some products pair with a compatible solar panel to charge using the sun, making them a home solar generator of sorts.

Solar

If camping is the primary intended use for a portable power station, then look for a portable solar-powered generator that can charge during the day in the sun. Come nighttime, the generator will be ready to provide hours of power.

In the past, solar power stations only had the capability to charge using sunlight, which greatly limited their reliability. However, manufacturers have begun combining solar and electric portable power stations to give users the option to charge using a traditional electric outlet; a vehicle power outlet; or detachable, portable solar panels. Steadily, this hybrid idea has become one of the best outdoor power station designs. It combines all the advantages of solar energy and the convenience of electrical outlets. Today, very few power stations offer only solar or only electric power.

Power Output

Power output of a portable power station refers to the maximum amount of energy the station delivers to the attached devices. 

Power output ratings are available in terms of wattage. How many watts a device will deliver explains how much power it can produce. The more watts a device can produce, the larger the electrical component it can run. For instance, a 100-watt power supply can power two 50-watt bulbs. However, it can’t run an air conditioner, which requires around 450 watts to run its compressor.

Power capacity is a different story, and it’s measured in milliamp-hours or watt-hours. Both terms explain how long the power station can power a device of a specific size. A power station with a 2,000-milliamp-hour battery can charge or power a device that draws 200 millilamp-hours for 10 hours. A station with 1,000 watt-hours can power a 1-watt device for 1,000 hours, or a 400-watt device for 2.5 hours. Generally speaking, smaller power supplies use milliamp-hours while the most powerful portable power station supply units use watt-hours.

Weight 

Electric and solar-powered generator units generally come in smaller and lighter than gas-powered generators, which makes them the ideal power station for camping and road trips. Folks looking for the best portable power supply will want to look for a manageable size and weight as well as features that facilitate transport, such as wheels and a carrying handle. 

Noise 

Consider how much noise a power station will make. Setting one up inside a home or workshop means close quarters, and loud models could literally require hearing protection. A portable power station for camping should also be quiet, or else it may disturb the neighbors. 

Typically, electric and solar power stations make for the quietest generators available. These products don’t make much noise at all because they only transfer stored energy. They hum no louder than a mini fridge. (For those who may require more electricity than a power station can supply, but still need a quieter source of power, inverter generators are a good option.)

Safety Features 

Anyone operating a device that uses electricity will want to be aware of the potential risks, like overheating. Look for portable power stations that have built-in safety features like an automatic shutdown function, overload protection, and an internal high/low-temperature gauge.

• An automatic shutdown function helps prevent premature degradation of the power station by turning the device off before it overheats or protecting the battery from discharging too deeply.
• Overload protection disengages the portable power station from the input current if it detects the current is exceeding a safe charge capacity.
• An internal high/low-temperature gauge measures the temperature of the battery and stops all input and output functions if the battery temperature falls outside of a safe range, as determined by the manufacturer.

Durability 

Whether using a portable power station at home, camping, or on the jobsite, invest in a product that will withstand any method of transportation and any possible impact damage that could occur. If you’re using the power station within the home or workshop exclusively as a backup power device, then a lightweight product will be fine.

If you’re using a power station for camping, consider products that offer water and ultraviolet resistance. On a jobsite, look for a heavy-duty product that won’t break down if a wrench or hammer falls on top of it.

Battery and Charging Method

Portable power stations typically come equipped with lithium-ion batteries that hold a significant amount of stored electrical energy. Most power stations plug directly into a standard electrical outlet, but many models don’t require access to a wall outlet.

Some portable power stations charge in cars with the proper adapter—a great method for camping and road trips. With the right conditions, solar charging works well. These models need a compatible solar panel, the appropriate weather for efficient solar charging, and a suitable place to leave the portable power station where it will absorb solar energy. Power stations with multiple charging methods make an excellent resource for long camping trips because they help to ensure power in almost any situation.

Heating and air conditioning strip a home’s indoor air of its natural humidity. The result of uncomfortable dryness leaves skin feeling dehydrated, contributes to sinus and respiratory problems, and even promotes static electricity—that annoying shock that occurs upon crossing a carpeted room and touching the television.

A little added moisture in the air helps alleviate dust mites, reduces allergy symptoms, and soothes irritated nasal passages. In addition to a handful of household hacks, residents can rely on humidifiers to help the situation. Humidifiers have been around for decades, but today’s models offer more choices than ever before. We’ve done the legwork and found out what features buyers want most in humidifiers as well as which models they rate as the best humidifiers.

Keep reading to learn all about today’s room humidifiers, hear what experts have to say about these devices, and discover why we’ve selected these as top choices, depending on a person’s individual home and needs.

How We Chose the Best Room Humidifiers

Room humidifiers can do more than just improve the air quality. They can soothe dry skin, chapped lips, and help relieve a dry throat and common cold symptoms. However, there’s no one-size-fits-all solution, so consumers will want to check the variety available before making their choice.

During our own research, we looked at over 50 of the best room humidifiers currently available before landing on our carefully collated selection. We wanted to incorporate the various types, account for different room sizes, and choose models that were as easy to operate and maintain as possible. We looked for a range of humidifiers that would satisfy every need.

Price is always a consideration, and many of our picks offer excellent value for money. We also included a few high-end models for those who are prepared to pay a little extra for their comfort.

Evan Scobria, founder of Prime Home Humidity based in Bellingham, Washington, provides consumers with the latest information about humidifiers, dehumidifiers, and home humidity. “The mist created by room humidifiers protects wood floors and wood furniture from the damaging effects of overly dry air,” he says. In sum, the devices “are an effective remedy for low-humidity home environments.”

What to Consider When Choosing a Room Humidifier

Getting the best room humidifier for your needs involves considering the differences between warm mist and cool mist models, room size requirements, humidistat features, ultrasonic technology, and cleaning considerations. Additionally, for households with young members, it’s essential to explore child-safe options to ensure a secure and family-friendly choice.

Warm Mist vs. Cool Mist Humidifiers

Both cool and warm mist humidifiers add much-needed moisture to dry indoor air, with slight differences:

• A standard warm mist humidifier brings water to a boil to inject the room’s air with a little extra moisture. The high heat reduces the risk of bacterial transmission, leading it to be considered slightly healthier. Warm mist humidifiers are also typically quieter to operate since steamy mist naturally rises, eliminating the need for an internal fan. They do require additional cleaning because the boiling process leaves behind mineral deposits.
• A cool mist humidifier (also called evaporative) uses a fan to blow air through a damp wick, so it can be noisy when it turns on. Cool mist humidifiers are preferable to warm mist humidifiers in homes with small children since there is no danger of burning little fingers.

Ultrasonic Technology

Ultrasonic humidifiers can disperse a warm or a cool mist, or both. The cool mist option is more common, but some models include an internal heater that facilitates a cool mist in the summer and warm mist in the winter. Instead of utilizing a strong fan, as a standard cool mist humidifier might, an ultrasonic humidifier breaks up water droplets into mist using a ceramic diaphragm that vibrates at a frequency too high to be audible to the human ear. Best of all, most ultrasonic humidifiers are whisper quiet, so they won’t interfere with sleep.

Size

A humidifier that is too small may not be sufficient, while one that’s too large could add so much moisture into the room that droplets appear on furniture and other surfaces. Fortunately, humidifiers are rated by the intended room size.

• A small room humidifier effectively treats rooms with less than 400 square feet of floor space. They are often portable and lightweight, making them a good choice for bedrooms, nurseries, kitchens, and other small spaces.
• Medium-size room humidifiers treat rooms between 400 and 900 square feet and are only semiportable.
• For a room with 1,000 square feet or more, look for a large room humidifier. Large room humidifiers feature bigger water reservoirs and are stationary.

Humidistat

A humidistat is a concept similar to a thermostat on a heater, except a humidistat is used to set the desired humidity. The humidifier will then turn itself on and off automatically to maintain that level. Many room humidifiers have a humidistat, though by no means all. Cheaper models may just pump out moisture at a preset level and need to be turned on and off manually. Unfortunately, this isn’t convenient for rooms that are unattended and can lead to over or under humidification.

Often the humidistat is a sensor with a simple dial, and some experimentation is needed before the preferred level is established. Others allow precise setting of humidity at a given percentage. Smart humidifiers can even allow this to be set or changed remotely.

Cleaning

Humidifiers need regular care for two reasons. First, it keeps them operating at peak efficiency and should prolong their working life. Second, mold and bacteria can build up on the unit, potentially creating a health hazard. The U.S. Environmental Protection Agency general advice is to clean humidifiers every third day, though we would recommend following each manufacturer’s specific instructions for its machine.

Some high-end room humidifiers have cleaning cycles that make life a lot easier. Of course there is a premium to pay for this functionality. Fortunately, cleaning humidifiers by hand is not difficult, usually requiring just white vinegar, water, a scrubbing brush, and a sponge or cloth. The Consumer Products Safety Commission recommends the use of demineralized or distilled water to reduce mineral buildup, though some manufacturers disagree. A few actually warn against their use, so be sure to check instructions for each device.

Before You Buy a Salt-Free Water Softener

According to Roy Barnes, master plumber and co-owner of Rockville, Maryland’s Service Force Plumbing, the term “softener” is a bit of a misnomer. “Water softeners actually eliminate the causes of hard water, mostly calcium and magnesium, and make it ‘un-hard’ (i.e., soft). Salt-free systems don’t actually remove [these minerals] but seek to mitigate their effects.”

Salt-based water softeners require the regular addition of salt in combination to draw out minerals, preventing them from causing scaling on plumbing while also making soap sudsier for bathing, washing dishes, and cleaning clothes. 

As their name suggests, salt-free systems don’t use salt. Rather, they soften hard minerals so they don’t build up on faucets and showerheads. While salt-free water softeners are an excellent option for many homeowners, they may not be adequate for those with very hard water or serious issues like lead contamination. To help decide whether a salt-free water softener is right for you, consider your home’s water quality by looking for signs your home needs a water softener and performing a hard water test.

How We Chose the Best Salt-Free Water Softeners

When gathering our top picks for water softeners, we included both salt-free water conditioners that are simple electromagnetic units as well as whole-house filtering systems that provide additional benefits. Electromagnetic units are typically small water softener systems that are relatively inexpensive, simple to install, and require little to no maintenance. Rather than removing minerals, they simply alter them to prevent them from causing scale buildup. 

Whole-house filtration systems filter out common water contaminants in addition to softening water, providing a more comprehensive water treatment solution. While these larger salt-free water conditioners may require professional installation, they are worth the investment for those dealing with problems caused by hard water or looking for well water softener systems.

What to Consider When Choosing a Salt-Free Water Softener 

Understanding how the best salt-free water softeners work and how much water they can treat each day is integral to purchasing the right soft water system for a home. 

Type

There are several types of salt-free water softeners on the market, each with its pros and cons. These types include polyphosphates, electromagnetic and magnetic, and full filtration. 

Polyphosphates 

The use of phosphates to soften water is a practice that dates back nearly 200 years. Instead of removing impurities from the water, this process conditions the water so impurities cannot create scaling on plumbing or faucets using a filtration cartridge. This type of system is used primarily in restaurants and other commercial settings to protect appliances from scaling.

Electromagnetic and Magnet

Like all salt-free water softeners, electromagnetic softeners don’t remove hard water particles but instead condition them to prevent scaling. These softeners work by magnetizing mineral grains so they don’t adhere to surfaces, a process that doesn’t require plumbing but does require power from an electrical outlet. 

Magnetic models perform the same task but without the use of electricity. However, they are not as powerful as electromagnetic models and are only suitable for very small homes.

Full Filtration

Whole-house water filter and softener systems soften water and remove other contaminants. They typically require installation into your home’s main plumbing line and work by crystallizing minerals so they don’t stick together and cause scaling. Since they also remove contaminants like herbicides, bacteria, viruses, pesticides, and chlorine, they are generally more expensive than basic salt-free systems. Their filters also require regular replacement. 

Size and Water Usage

The best salt-free water softeners come in different sizes to meet each household’s water usage and hardness needs. Needing to treat harder water can increase a water softener system’s cost. 

To calculate water usage, multiply the number of people living in your home by the average use rate of 75 gallons per day. Using this equation, a family of three will use an average of 225 gallons of water per day. 

To determine water hardness, which is measured in grains per gallon, you’ll need a water test kit. Water with 7 to 10.5 grains per gallon is moderately hard, while water with more than 10.5 grains per gallon is very hard. 

To calculate which size softener you need, multiply water hardness by water usage. A home that uses 225 gallons of water per day with a water hardness of 10 grains per gallon requires a water softener with a capacity of 2,250 grains per day. 

Flow Rate 

A salt-free water-conditioning system sits between the main water line’s intake and outtakes, treating water as it flows into your home’s plumbing. Since electromagnetic water treatment systems aren’t plumbed into your home’s water system, they don’t affect flow rate. 

However, salt-free systems that use filtration can affect water flow, potentially slowing it. Therefore, water softeners with filtration systems must have a flow rate that meets the demands of the household to prevent a drop in water pressure. Homes with one to three bathrooms need a filtration system with a flow rate between 8 and 12 gallons per minute. Larger households require around 15 gallons per minute.

Installation

Installing a water softener that’s salt free is generally relatively easy. While traditional salt softeners typically require professional installation, salt-free systems don’t require any plumbing knowledge and will likely only take about 15 minutes for the average DIYer to install. All you need to do is wrap the unit’s wires around your water supply pipe and plug it in.

Full filtration systems and whole-house systems are more involved. Unlike under-sink water filters, descaler and filtration combination systems generally need to be plumbed into the incoming water supply pipe. Still, these units are typically designed to be relatively quick and easy to install, meaning some DIYers may be up to the task. 

The Advantages of Using a Salt-Free Water Softener

The benefits of a soft water system that’s salt free range from producing healthier water to being easier to maintain, install, and operate. 

• They’re healthier: Unlike traditional water softeners, salt-free water softeners do not use sodium chloride, meaning they don’t add salt to drinking water. This can be a significant benefit if members of the household must limit their salt intake due to high blood pressure or other health issues. 
• They’re low maintenance: Unlike traditional water softeners, which must be refilled with 40 pounds or more of salt each month and periodically cleaned, salt-free water softeners require very little maintenance. While some units have water filters that must be replaced every 3 to 6 months, electromagnetic models require little to no maintenance whatsoever. 
• They have low operating costs: Since traditional water softeners require a steady stream of water softener salt and electricity to create the ionization process that softens water, they have higher operating costs. Salt-free systems do not salt, meaning they are less expensive to operate over time. 
• They protect plumbing and appliances: As with salt-based water softeners, salt-free water softeners eliminate scaling that can clog pipes. This helps optimize the performance of washing machines, hot water heaters, and dishwashers. 

FAQs

Though you likely aren’t still asking yourself, “What is a water softener?” you may still have questions about how salt-free water softeners work or if your new water softener is functioning properly. Below are answers to some of the most commonly asked questions about these appliances.

The TopDon TC005 impressed us right out of the box. We liked its build quality and non-slip ergonomic design. Weighing just over 1 pound, it has enough heft to feel substantial yet is not cumbersome. It comes with a canvas case with a belt loop and a strap for carrying the camera across the body. The package also includes a 16 GB memory card and a USB cord for charging and transferring images to a tablet or PC. 

We liked how intuitive using the TC005 was. It has four imaging modes we could scroll through to find the best visibility depending on what we were looking for. The heat signature was brightest in infrared (IR) mode, but we could also switch to visible light, which was handy if we wanted to take pictures both with and without IR for comparison on a computer later. The other two modes combine infrared and visible light in different degrees.

Taking a photo requires a simple trigger squeeze, and the image is automatically saved to the memory card. Scrolling through the images on the camera display gave us a quick view, but the best way to see them is to upload them to a computer. We downloaded TDView, Topdon’s app for viewing the images, but they can also be opened with other image editing programs, such as Photoshop, Windows Viewer, and Lightroom. 

The TC005 provides vital heat signature information by marking each image’s hottest, coldest, and central temperatures with little bullseyes. It also displays the corresponding numerical temperatures in Celsius or Fahrenheit. 

The TC005 may lack the sensitivity needed for specialized fields such as industrial engineering, but it’s a solid pick for DIYers, home mechanics, and pros looking to detect drafts, insulation issues, and electrical hotspots.

How We Chose and Tested the Best Thermal Cameras 

In selecting thermal cameras for our lineup, we researched more than 20, narrowing the list based on features, build quality, and consumer feedback, and then chose the TopDon TC005 for hands-on testing. While Flir makes some of the best thermal cameras around, they can be pricey, and we wanted to test a model that would be well-suited to a wide range of users. 

In actual testing, we used the thermal camera in the same ways most DIYers would. We checked around our doors and windows for heat loss. We scanned outlets and monitored plugged-in appliances to see if the cords were overheating. We checked our automobile engine to see if there were any concerning hotspots, and even had a little fun taking thermal photos of our dog. 

We paid special attention to the temperature ranges detected by the TC005 and noted how easy it was to use the thermal camera, and also downloaded the app and used it to view our thermal images. 

What to Consider When Choosing a Thermal Camera

The best thermal camera for your needs can depend on several factors, including size, temperature range, resolution, image enhancement capabilities, and task-specific accessories, such as wall probes for leak detection. Here are a few things to consider before selecting a thermal camera. 

Types of Thermal Cameras

Thermal cameras fall into three main categories based on how they are used. The types are handheld thermal cameras, infrared phone camera attachments, and thermal drones.

Handheld Thermal Cameras

Handheld thermal cameras are commonly used for household inspections and for many industrial applications. This type of heat sensor camera can have a small body the size of a smartphone, or it can be large enough that it necessitates the use of a camera grip for proper focus.

For the majority of thermal camera applications, such as looking inside a home’s walls, floors, or other spaces, a handheld thermal camera is suitable. While these cameras are larger and more expensive than a smartphone attachment, they also may have thermal camera-specific screen resolutions and a wider range of features, including contactless body temperature readings, a built-in laser guide, or a visual light camera. 

Smartphone Thermal Camera Attachments

A smartphone thermal camera attachment allows you to use your smartphone to read the heat signatures of infestations or your electrical, HVAC, and plumbing systems. The attachment plugs into the base of your device so that you can simply control the camera through your touchscreen and upload the collected pictures or scans directly into your phone.

This type of device is inexpensive and easy to use, making it a great option for infrequent or DIY home inspections, but it is not recommended for professional use. This is because cheap thermal camera attachments lack the high image quality and precise measuring accessories that handheld thermal cameras normally offer. They may also drain your smartphone battery quickly, ultimately limiting viewing time.

Thermal Drones

Using a thermal drone for a home inspection might seem like overkill, but there are many issues that cannot be detected from inside the house. Unless you are willing to get up on a ladder or another high perch, a thermal drone is a great way to find out if you have any hidden problems. 

Possible problems that a thermal drone can help detect include nesting insects, such as termites or other animals, blockages in the drainage system, and areas in the roof or exterior walls where heat is escaping, indicating the need to repair a hole. These devices combine the flight capability of a drone with the functionality of a thermal camera. However, they are usually quite expensive and are better suited for those with a professional roofing or home inspection business. It is also possible to find a thermal camera to attach to an existing drone for drone photography. 

Size, Weight, and Grip

The size and weight of a thermal camera are also worth considering if the device is going to be used for any extended period of time. Heavy or large cameras or those with an uncomfortable grip can contribute to or help avoid hand fatigue.

Small thermal camera smartphone attachments are easy to carry, but they don’t have the same kind of stable grip as standalone thermal cameras. Smartphone attachments are great for travel and quick inspections, but they are not suited for long periods of use. Handheld thermal cameras can range in size, but those best suited for comfort typically come with a padded camera grip that is easy and comfortable to hold. Because thermal drones can fly, their size and weight matter less, but the comfort of their handheld controllers determines how long the user can control the drone before hand fatigue sets in. 

Temperature Range

When looking for a thermal camera, you will notice that the manufacturer typically states the minimum and maximum temperatures that the device is capable of accurately reading. Smartphone attachments normally have moderate thermal sensitivity from -4 to 248 degrees Fahrenheit, while handheld thermal cameras may extend the temperature range from -13 to 716 degrees Fahrenheit. 

Larger temperature ranges allow you to detect problems that can’t be seen with the human eye in HVAC systems, hot water tanks, or vehicles. Thermal drones typically have a similar range to handheld thermal cameras, with the added bonus of flying capabilities. When shopping for a camera, keep in mind the highest and lowest possible temperatures you would normally find during your inspection.

Resolution

The thermal resolution of a thermal camera can help a user hone in on potential issues. The more precise a thermal camera is, the easier it is to pinpoint exactly where the problem lies, potentially saving you from making costly mistakes.

For example, a low-resolution camera may present a broad-spectrum image of a plumbing system that vaguely shows an increase in temperature extending outside the pipe. While this information helps to determine that a hot water leak or insulation gap exists, the reading may not show the exact location of the leak. With a higher-resolution camera, you can identify the flow of water and open a hole just wide enough to stop the leak. 

To accurately recognize and diagnose what you are seeing through the thermal camera screen, you need a high thermal resolution. Thermal resolution quality is measured in pixels and can range from as low as the 60 by 60 pixel resolution commonly seen on smartphone attachments to as high as 320 by 240 pixels. A higher resolution may be especially important for professionals looking for a precise thermal imaging device to identify and target repair needs.

Accuracy and Repeatability

Temperature accuracy, which is measured in degrees Celsius or degrees Fahrenheit, is another factor that can help ensure precise readings with a thermal camera. For example, the Occupational Safety and Health Administration suggests that hot water heaters should heat water to a temperature of 140 degrees Fahrenheit to prevent the spread of certain diseases, but the American Academy of Pediatrics recommends a setting of between 120 and 130 degrees Fahrenheit in homes with small children to prevent accidental scalding and burning, and the Consumer Protection Safety Commission has similar recommendations to protect the elderly, so precision is important.

An accurate thermal camera can verify that a hot water heater is performing to the appropriate standard or if it needs to be repaired or replaced. Typical thermal cameras have an accuracy range of plus or minus four degrees Fahrenheit, though there are more accurate thermal imaging cameras.

The accuracy range accounts for several factors that can affect how infrared energy is measured. These can include ambient temperature, camera response, emissivity, transmittance, calibrator temperature accuracy, and atmospheric temperature. The more repeatable a reading is, regardless of these intervening factors, the more accurate a camera will be.

Thermal Image Enhancement

Along with a high-definition thermal resolution, a camera can enhance its thermal image by using overlays of nonthermal video recording. This feature makes visible low-contrast objects even in areas with very wide temperature ranges, allowing you to differentiate between two similar targets. 

The result is a detailed thermal image with overlays of sharp corners and edges that give the objects some identifiable structure. This feature can help identify studs in a wall, plastic pipes, and even furniture in a dark room. It is typically used by firefighters to quickly identify their surroundings so that they can take appropriate actions to put out the fire and help anyone nearby.

Visible Light Image Enhancement

Thermal cameras do not typically need visual light to create thermal depictions of an object or objects. However, it is easier to identify possible problems and anomalies in electrical, plumbing, HVAC, or even automotive systems when the structure is visible to the naked eye. 

To this end, some thermal cameras have a visual light enhancement feature that illuminates low-light video to better highlight the outline and structure of scanned objects. With this feature, you might also be able to change the visual tone and appearance of the output—almost like choosing a photo filter—to find the best view of the problem.

File Formats and Data Output

Thermal cameras don’t only allow you to view and identify possible issues in real time. They can also be used to take a picture or video, which you can then send to your repair technicians so that they are better informed before showing up to help fix it. 

Home inspectors and many other industry professionals who use thermal cameras regularly need to be able to take photos, store them, and even send them wirelessly to others. Thermal cameras may have BMP or JPEG file formats. BMPs can be difficult to convert to a readable form, while JPEGs can be read by most devices.

Data can be saved on the camera or it can be saved on a computer or another device. This usually requires a USB-C cord, but some cameras can connect to Wi-Fi. A thermal camera snap on attachment can send data directly to the connected smartphone, where it can be read much like on a computer.

Companion Tools

Thermal cameras can be used for many different purposes and typically do well as standalone tools. However, many thermal cameras come with accessories designed to help detect specific problems, such as using moisture meter probing bars to better find plumbing leaks. Another frequent companion tool is a voltage detector that can detect the presence of electrical voltage with vibration, lights, or sound alarms. 

Depending on the purpose, a variety of useful companion tools including clamp meters, moisture pens, voltage detectors, moisture detectors, and even thermoprobe connectors that can infrared measurements through narrow gaps may augment the usefulness of the camera. 

Tips for Using a Thermal Camera

Though most thermal cameras are pretty straightforward, there are a few things to keep in mind in order to ensure accurate temperature readings. One of the most important points is to steady the aim of the camera and ensure you have the correct resolution and optics for the type of temperature measurement required. 

You should also check that your field of view is suitable for the type of measurement you are taking. For example, if you are closely inspecting your home, a wider field of view on your thermal camera may be more effective. Alternatively, when scanning things at a distance, a narrow view may be ideal. Here are a few more tips to consider before using a thermal camera: 

• Ensure you understand the colors produced on a thermal camera. Standard colors are red, orange, and yellow for heat and blue and green for cooler areas. 
• Adjust the focus and field of view on your camera before and during readings to ensure clarity and accuracy. 
• If your thermal camera runs on battery power, make sure to carry a charger or extra battery with you while taking measurements.

How We Chose and Tested the Best Hygrometers

Testing how accurately the above hygrometers measure humidity required us to calibrate each device before we could do anything else. This YouTube video details the process, but the short synopsis is that we put a small amount of salt and hot water next to each hygrometer in an airtight container and left them alone in a closet for 24 hours. We then checked their readings and determined how accurate they were. We adjusted the models that allow calibration and noted how far off the other units were. 

We then tested each unit over for at least 5 days and as long as several weeks, setting them up next to each other indoors, outdoors, and in the bathroom after showers. We kept handwritten logs and downloaded dozens of CSV files, checking for quick response time to changing conditions and overall accuracy regarding humidity and temperature readings. For Bluetooth and Wi-Fi units, we monitored connectivity at half range and maximum range, noting whether walls affected accuracy. 

What to Consider When Choosing a Hygrometer

Beyond HVAC efficiency, maintaining proper humidity levels can improve health by helping to keep sinuses clear and making it easier to breathe. Accurate humidity control is also essential for protecting wine, cigars, plants, and keepsake items.

Choosing the best hygrometer requires careful consideration. Begin by determining where you will use the device, as indoor and outdoor hygrometers will have different features. Then consider whether you need advanced features like smart connectivity, unlimited data storage, or extended battery life—or if simply knowing the current conditions is all that matters. 

Types of Hygrometers

Hygrometers come in several variations, but each is effective at sensing and displaying the humidity in a given environment. While the most popular hygrometers are electrical or mechanical, dew point hygrometers and psychrometers are worth learning about to appreciate the science behind these instruments. 

Keep in mind that many hygrometers also display the temperature to serve as indoor thermometers as well. This can be particularly helpful in food storage spaces or wine cellars.

Electrical

Electrical hygrometers are the most widely used and high-tech hygrometers available. These devices measure the changes in electrical resistance across a semiconductor or sensor that reacts to the air’s moisture content. As the moisture content changes, the resistance increases or decreases, which the hygrometer displays digitally.

Today, most electrical hygrometers use batteries for power. Several models have Bluetooth connectivity, allowing users to check the hygrometer’s readings from the convenience of their smartphone. Others may operate on the home’s Wi-Fi, alerting the user to the conditions in the home so they can run a humidifier or dehumidifier to adjust the levels. 

Mechanical Hygrometers

Anyone who’s perused the tables at a child’s science fair has probably seen a mechanical hygrometer. This popular science project uses the changes in organic materials caused by moisture content to display humidity levels.

In their simplest form, mechanical hygrometers use organic materials like oxgut or human hair to control a needle that points to a humidity scale. When the moisture content in the air rises, the organic material absorbs the moisture, contracting and becoming heavier, which in turn raises the needle. As the air dries, the material becomes lighter and stretches a bit, allowing the needle to fall.

Dew-Point Hygrometers

Moisture condenses on the polished-metal mirrors of dew-point hygrometers. By noting the air temperature at which water begins to condense on the mirror, experimenters can determine the dew point. To provide accurate readings, these devices require extremely consistent conditions, including constant atmospheric pressure and constant vapor content.

Dew-point hygrometers are very old-school technology, with the first invented in 1751. They aren’t used much, if at all, anymore, but modern hygrometers owe a bit of credit to this early device.

Psychrometers

While psychrometers don’t adorn the windows of many kitchens or greenhouses, they are still in use in meteorology. They’re also popular in wildland firefighting for detecting the danger and potential for a fire.

Psychrometers use two types of thermometers to measure the air’s moisture content. It’s a rather complicated process that involves wrapping one of the thermometers in a wet cloth and spinning both thermometers. The experimenter then enters the readings from the thermometers into an equation to determine the humidity level.

Application

How you intend to use a hygrometer makes a significant difference when choosing the best model. For instance, users may want a different product to monitor the humidity level of a greenhouse than to check on the conditions inside a reptile tank.

For most situations, a digital hygrometer that users can place on a bookshelf or table will serve just fine. However, some might prefer a minuscule hygrometer or one that operates without a battery for niche needs and applications. 

Accuracy

On the whole, hygrometers are relatively reliable and consistent instruments. The most accurate hygrometer models are within 5 percent of true values. Beyond that, accuracy comes down to calibration. 

Folks who suspect their hygrometer’s accuracy might be off a bit need to calibrate it. They can purchase a hygrometer calibration kit, which requires placing the hygrometer in a sealed bag for a prescribed length of time. The hygrometer reading relative to the kit’s percentage will determine if it needs calibration. Digital hygrometers may have calibration knobs or reset buttons, smart hygrometers are typically easy to adjust via app, and most analog hygrometers have adjustment screws in the back.

Digital vs. Analog

When it comes to reading a hygrometer quickly from a distance, it’s hard to beat an analog hygrometer. These mechanical hygrometers have needles that point to the general range on the dial, which is all folks need in most scenarios. The drawback of an analog dial is that it’s hard to tell the exact reading even up close, and these devices cannot measure more precisely than a full percent, while digital hygrometers can measure a tenth, hundredth, or even a thousandth of a degree. While this level of precision isn’t necessary for most users, it may be for some.

Digital displays are the choice to go with when it’s important to know the exact value of the humidity. With an electric hygrometer’s digital display, if the moisture begins to change, users will likely notice it sooner and more easily. The numbers will change as opposed to tiny movements from a needle. The downside is that low-quality or small digital displays can be challenging to read, as some digits can be hard to decipher from one another from a distance.  

Power Source and Battery Life

Some countertop-style hygrometers come with 110V electrical adapters that plug into an outlet for unlimited runtime, although most run via battery power, with battery life lasting 6 months or more. Some models use rechargeable batteries, which can be particularly handy as long as the battery life lasts for a significant period of time. 

Longer battery life may be especially important for remote monitoring using Wi-Fi or Bluetooth-enabled devices. For instance, when tracking plant humidity in a terrarium that needs to be kept closed as much as possible, it’s important to get a terrarium hygrometer sensor that’s thrifty with battery life. 

Remote Monitoring and Alerts

Monitoring humidity levels isn’t always about personal comfort or convenience. Sometimes, it’s required by a favorite hobby or pursuit. For instance, monitoring a wine cellar or cigar humidor’s humidity level can be the difference between maintaining a wonderful selection or spoiling an expensive collection, and some wood musical instruments require precise humidity levels to avoid cracking that will destroy them.

For help keeping these areas within a crucial humidity range, it’s worth purchasing a hygrometer that relays data to a smartphone or a remote display. Most important, perhaps, is the ability to set a particular range and send alerts when the humidity is outside that range, which can help users take action before their cache spoils or molds.

Interconnectivity and User Interface

Thanks to advances in Bluetooth, Wi-Fi, and smart-home technology, there are plenty of options for connecting a hygrometer with personal technology. 

Many of these devices use their own apps, allowing users to monitor the humidity levels via Bluetooth from a smartphone. This can be a great help when trying to avoid opening a sensitive environment like a greenhouse or terrarium. However, be aware that not all apps are equal in usability and function, so check into this before deciding on a compatible hygrometer. 

From a smartphone, hygrometer users can access temperature and humidity readings in their homes when they’re not even there by using a WiFi-enabled app. Some of the best hygrometers can interact with smart-home devices, too. They provide their readings via Alexa, Google Assistant, or other digital assistants. If the user can access a home thermostat from their smartphone, they can adjust the home’s temperature settings based on information from the hygrometer’s app.

Data Logging

Those who are serious about controlling the humidity in their homes for health reasons, hobbies, or any other purpose need to collect data. They might want to consider a hygrometer that keeps a log of humidity values and temperatures. They can track that data and stay ahead of seasonal or environmental trends, maintaining a more consistent environment.

Some devices keep data logs in their apps, so users will have up to 2 or more years’ worth of information at their fingertips. Even more helpfully, they can export a spreadsheet of this critical data, which they can then store on a computer or print out.
