Portable generators are crucial during power outages and helpful for remote locations, and inverter generators are the crème de la crème in terms of efficiency.

Similar to traditional models, inverter generators come in different sizes and outputs, but they use a computer-controlled inverter to provide usable power as needed. This makes them lighter, quieter, and more efficient than traditional open-framed generators, which supply a set amount of power regardless of current needs.

Inverters are still relatively new generators on the market, so we wanted to test the bestselling models before making recommendations to our readers. The Bob Vila test team put several brand-name inverter generators to the test at their homes to see how they performed.

Keep reading to learn what sets these generators apart from traditional models and how they fared in our hands-on tests. Our top picks vary in output and intended use, and they are all worthy of their spot in our lineup of the best inverter generators.

We researched over 25 different makes and models of inverter generators before selecting several top options for testing. When compiling this list, we considered brands like Champion and Honda since they’re well respected in the generator industry. However, we didn’t automatically cut machines from smaller companies like Wen and Ryobi if they had good features and high customer satisfaction ratings.

For our real-life tests, we assembled the generators and followed the manufacturer’s instructions for fueling and operation. We tried to max out each generator, estimating how many items we could plug in using an online wattage calculator. We powered tools, appliances, heaters, mini AC units, and more, noting how to use the generators and how much noise they emitted when running.

After testing, we awarded each inverter generator points based on a rubric. We assigned them ratings for ease of use, noise, power, portability, and value.

A note on noise level ratings: Many generators are inherently loud. Therefore, we scored each generator’s noise on whether it matched the expected levels set forth by the manufacturer and what would be reasonable given the machine’s wattage. If it was louder than expected, we rated it lower. If it was quieter, we rated it higher.

Westinghouse’s iGen4500 inverter generator is both a high-tech and high-functioning model. It offers a variety of power ports, including a 30A, two 20A, and two USB. In our tests, we used it to charge our digital devices while also powering the appliances in our travel trailer.

The iGen4500 has a 3.4-gallon gasoline tank that can run up to 18 hours. As an inverter generator, it only burns as much fuel as needed to power the appliances or tools plugged in. This makes it more eco-friendly than a noninverter model that burns fuel at a set rate no matter how much power is being drawn.

However, with a weight of almost 105 pounds without fuel, we found it challenging for one person to lift it into and out of our truck bed. Once on site, its setup was simple: We added oil, filled the gas tank, and were in business. While this would be a great emergency generator, its quiet and efficient operation makes it a top-notch pick for RVs, camping, and remote powering.

The Pulsar 2200-watt inverter generator is a great option for powering small tools and devices at home or on the jobsite. The generator uses gasoline or propane and supplies up to 1,800 running watts with gas and 1,600 with propane.

During our tests, we found the initial setup of the generator to be easy, except for filling the oil for the first time. The fill port sits under a side panel we had to remove to gain access. Unscrewing the panel was easy enough, but it took some budging to get it to pop off completely. After that, filling it up with the supplied Pulsar-brand oil was straightforward.

The engine’s recoil start requires just a couple of pulls before the engine kicks on with 2,200 watts (using gas) of startup power. To test the generator’s capabilities, we ran a couple of heat guns and hair dryers simultaneously, using different combinations of high and low settings to test it at different loads. We found the generator easily handled the necessary output, but it seemed to produce more than the advertised 59 decibels, which is about the level of conversation. The Pulsar sounded a bit louder, more like a vacuum, though that’s about the sound level we’d expect from a generator of its size.

Despite the slight sound issue, we like this generator for light-duty needs, such as small DIY projects and powering a couple of household appliances during an outage.

When it comes to clean electricity, inverter generators provide a stable current free of voltage spikes and drops. But, not all inverters are “clean” in terms of their impact on air quality. The Generac iQ3500 inverter generator offers the best of both worlds. As a California Air Resources Board (CARB)-compliant inverter generator, it safely and quietly powers sensitive electronic devices while consuming less fuel and emitting less pollution.

It comes equipped with a locking 30A outlet, a 20A duplex outlet, and two USB ports to power a wide range of tools and appliances. Two premium features that set it apart include a large LCD screen that displays power output and fuel levels and a push-button ignition switch.

The unit’s 20A duplex receptacle gave it more flexibility for powering high-draw tools and appliances than the 15A alternative on other inverter generators. We used it to power two 1,500-watt space heaters simultaneously for over an hour without tripping the breaker. To test the 30A outlet, we used a three-way service cord to supply a portable table saw, miter saw, and router. Everything worked as smoothly as if plugged into the wall at the shop.

The iQ3500 had a lot of strong points, but easy transport was not one of them. It weighs 109.1 pounds and doesn’t have wheels. Yet this was still one of the all-around favorites for its easy startup, quiet operation, and convenient access to electricity.

The Ryobi 2,300-watt gas generator was a pleasure to test. Unboxing to startup took under 10 minutes, and the app walks users through the process while showing the same readings as the machine’s LED panel.

For our tests, we plugged in several work lights and used various power tools, including a circular saw, a reciprocating saw, a jigsaw, a hammer drill, and a sander. The Ryobi lagged a bit when we tried to run a table saw, and it didn’t provide enough juice for a heated t-shirt press, but otherwise, it met our needs.

We liked the convenience of being able to monitor the status of the Ryobi while sitting comfortably indoors. We were able to shut down the generator from the app but not start it, which is probably a smart idea in terms of safety.

The Ryobi is relatively quiet, registering 57 decibels from 10 feet away, and we could converse easily without raising our voices. This little generator would be an excellent pick for craft festivals and tailgating excursions. It won’t power a jobsite or all appliances in a home, but it’s perfect for smaller-power uses.

Despite being one of the more compact inverters we tested, the Champion Power Equipment 2,000-watt generator excelled. It comes with dual-fuel ability, meaning we could run it on either gasoline or propane. This makes it highly versatile when one fuel type is preferred.

The Champion produces up to 2,000 surge watts on startup and settles into a respectable 1,700 watts using gas. It has two standard outlets and a 12V car-type port. The generator’s gas tank is on the small side at 1.05 gallons, but it will run for 11.5 hours when pulling a 25 percent load. Connecting a 20-pound propane tank and pulling the same load will run up to 34 hours.

During testing, we used the Champion to run several appliances, including a coffee maker and a blender. However, when we tried to run all the items simultaneously, we overloaded the machine, and the safety shutoff kicked in and shut it down. Of course, that will happen with any generator if it’s overloaded.

One great thing about this dual-fuel generator is how quietly it runs. The manufacturer claims it creates only 53 decibels of noise, which we found to be accurate in our tests. It’s also relatively lightweight for a dual-fuel model at just 39 pounds, but it won’t be able to run all appliances in an outage. Still, it will power a few and keep electronic devices charged without creating a ruckus.

We tested the Wen DF250i 2,500-watt dual-fuel generator by plugging in a variety of small electronics, including a circular saw and a shop light. Because the circular saw required significant startup power (1,500 watts), the machine bogged down briefly before ramping up, but then it held steady.

For lower-wattage items, we ran the generator in eco-mode, which adjusts fuel consumption based on load size. The generator changed its speed, and since it wasn’t generating more power than needed, it was able to run longer.

At 18.2 inches high by 11.5 inches wide by 19 inches long and weighing 48.5 pounds, the Wen is portable and sized right for small power needs. It runs on propane or gas and features two USB ports and two standard household outlets. It’s ideal for a couple of cell phones, a TV set, and an array of lights at a campsite, or it can provide power to a small jobsite.

We tested the generator at an altitude of just over 5,000 feet. Although the manufacturer suggests installing an altitude kit (sold separately) when using the machine above 3,000 feet, we performed our tests without this kit and had no issues.

The Honda EU2200i inverter generator features a Honda GXR120 commercial series 121 cubic centimeter engine with a recoil starter. It generates 120 volts; up to 1,800 running watts (15A); and 2,200 peak watts. Its 0.95-gallon gas tank provides up to 3.2 hours on maximum draw or up to 8.1 hours with a 25 percent output load. This compact, quiet generator is convenient for tailgating, camping, and other remote power needs.

The Honda’s lightweight, compact build made it comfortably portable. The top handle and suitcaselike shape were good for one-handed transport. At about 48 pounds, we wouldn’t want to carry it all day, but moving it from the shed to the truck was no problem. Roller wheels would have been a nice addition. Frequent users could purchase a collapsible hand truck for easier mobility.

The simple output configuration of just one 15A 120V duplex outlet allowed us to use it like any household wall socket without worrying about overloading it. We powered a portable table saw and miter saw on one project, then a refrigerator (alone) for a few hours to see how it would respond. Everything worked perfectly. Since it doesn’t have USB ports, you’ll need a wall hub or power strip to charge devices or power up small electronics.

Inverter generators are a different breed than the open-framed conventional generators most people are familiar with. While both use fuel (gasoline, diesel, or propane), open-framed generators use an alternator to make usable power for homes, campers, and jobsites. The info below will help narrow down the options to find the best generator deals on units with the power, portability, and convenience you need.

Wattage is a critical factor in any generator specification. Inverter generators, like their open-framed counterparts, come in different wattage ratings. The higher the wattage rating, the higher the power output. Higher wattages usually mean larger, more expensive units, so here’s a guide to choosing the right size for a range of needs:

Compact, portable generators may be feasible for powering a radio or a small refrigerator. However, there is often less flexibility for plugging in other devices with a low-wattage model. Keep in mind that an inverter generator only supplies as much power as necessary. It doesn’t generate energy if it’s not being pulled, making this generator more of a clean power source.

Inverter generators typically use gasoline as a fuel source, but dual-fuel generators can run on propane as well. This is a big advantage, as it allows owners to choose the fuel used based on their needs, such as power-output requirements, fuel availability in the area, and the fuel type currently on hand.

Inverter generators have an isolated gasoline tank with a fuel capacity that ranges from as small as 2 gallons to more than 10 gallons. The larger the fuel tank is on the generator, the longer it can provide gasoline-based power. However, the size of the generator also increases.

Fuel capacity does not affect how much propane can be used with the generator. Propane gas is stored under pressure in canisters, which attach to the generator with a hose and pressure regulator for direct fuel consumption.

Inverter generators feature an electric start switch, recoil cord, or both ignition methods:

This ignition method is much easier than using a recoil cord, but it requires stored electricity in the generator. If you make generator mistakes like not charging the internal battery, the electric start cannot be used.

The generator can be started anytime, even after long-term storage in the garage or shed.

Purchasing a set of like-branded generators will often provide the ability to wire them in parallel, also known as load sharing. This means that one generator can be plugged into another using a brand-specific kit. This safely combines their wattages to produce even more power.

Additionally, owning two generators provides a fail-safe if one stops working. There is still the ability to produce power, just at a lesser output. Load sharing can be a less expensive way to produce enough wattage to run a whole house or power everything in an RV at once.

The most noticeable difference between inverters and open-framed generators is the amount of noise they produce.

To better understand generator noise output, consider these common sounds and their equivalent operating decibel level:

Inverter generators also use sensors to detect how much power they need to expend, throttling down for smaller loads and producing lower noise levels. Neighbors at home or in a campground will appreciate that a quiet generator has been purchased rather than a noisy, open-framed model.

Physical size and weight will be a factor for some shoppers. As the name suggests, suitcase inverter generators are top-handled units that can be picked up with one hand and carried easily, as they’re typically lightweight at about 40 to 50 pounds. The drawback is these units usually have 2,200 watts or under for power output.

Wheeled units provide much more power (3,000+ watts) but are large and heavy. These portable generators are more challenging to throw in the bed of a truck or a camper’s storage compartment. As such, using one of these units as a home generator may be easier.

Some users may struggle with the weight of larger, more powerful units. Thus, some portable inverter generators have wheels and handles for easier transport to desired locations.

Wheel kits may also be sold separately as an addition to a generator or a replacement for an older wheel kit. Either way, having a wheel kit will make transporting heavy portable generators much easier.

Looking for more information on inverter generators? Consider these answers to some of the most frequently asked questions about this particular type of generator.

Inverters take DC power created by a gas or propane generator and convert it to AC power for household appliances.

Inverter generators don’t use alternators like typical open-framed models might, which require the engine to work harder and produce more heat. For that reason, inverter generator engines are quieter. In addition, manufacturers can close them inside plastic housing for even better noise control without a risk of overheating.

In general, inverter generators are easier to use, more efficient, and produce safer electricity for electronics. For those reasons alone, many users might find them worth it. To help protect your investment, it’s also worth purchasing a generator cover.

Most inverter generators will have no problem running a modern refrigerator, which only needs 1,000 watts maximum at startup.
