This compact and lightweight inverter generator from Yamaha is about as portable as generators get. The generator is just 2.2 cubic feet in size and weighs less than 45 pounds, making it easy for a single person to carry by the molded top handle even when it’s loaded with fuel.

And thanks to the quiet and reliable power of this model, you’ll want to take this generator on a boat, to a tailgate party or a short trip, or anywhere around with you. The generator is able to deliver 1,600 watts of continuous power or 2,000 watts of surge power, making it ideal for running a handful of lights and appliances at an outdoor event or for powering tools around the yard or a worksite. The four-stroke air-cooled Yamaha engine is extremely fuel efficient and runs for 10.5 hours at a 50% load – one of the best runtimes of any inverter generator that we reviewed. On top of that, even when running this generator at full power it produces just 61 dB of noise.

Users also appreciated that it’s easy to store this generator in the garage during the winter months, since the carburetor can be completely drained of fuel without running the generator empty. A fuel level indicator in the cap also makes it easy to monitor fuel consumption when the generator is in use.

While the outlets on Yamaha EF2000iSv2 are relatively limited – there are only two 120V outlets and a 12V DC battery charging outlet – most users did not find this to be inconvenient given the limited power output of the generator. The only convenience feature missing was an electric start, but users found that the recoil starter was highly responsive.

Yamaha offers a long three-year warranty on this generator.

Pros
  • Highly compact and lightweight
  • Long 10.5-hour runtime at 50% load
  • Carburetor can be emptied

VIEW ON AMAZON

This 2,000-watt generator from Honda handily beats out the competition for anyone looking for the absolute quietest inverter generator on the market. The Honda EU2200i produces just 48 dB of noise – about the same noise level as a loud conversation – when running at low power outputs and rises to a maximum of just 57 dB – the minimum noise level on many other generators we reviewed.

Despite how quiet this generator is, it delivers well on power. The generator offers up to 2,200 watts of surge power and 1,800 watts of continuous power. Users note that the 121cc Honda GXR120 engine lives up to the hype around Honda engines when it comes to reliability, and Honda provides a lengthy three-year warranty on the engine as well.

Where this inverter generator does suffer is in runtime. The generator is not the most fuel efficient of models and has a surprisingly tiny 0.95-gallon tank, which together limit the generator to a runtime of just 8.1 hours at a 25% load. That means that if you want to run the generator anywhere near its power capacity, you’ll only get a few hours of use before having to turn it off, wait for it to cool down, and add more fuel.

The other big drawback to this generator is the price. At well over $1,000, this is the most expensive inverter generator we reviewed. However, users will tell you that the reliable Honda engine, extraordinarily quiet operation, and long warranty is well worth the price.

Pros
  • Extremely quiet
  • Reliable Honda engine with three-year warranty
  • Easy to start

VIEW ON AMAZON

This inverter generator from Champion boasts a higher power output than comparable inverter generators as well as the ability to run on either gasoline or propane. The latter is a major advantage if you plan to use this generator for powering your home in the event of a power outage, as propane stores much better than gasoline. Plus, running a generator on propane allows you to dramatically reduce your fuel costs and keep the generator going without regard for the limited runtime when powering it with gasoline.

The generator offers an impressive 3,400 watts of surge power on gasoline or 3,060 watts of surge power on propane, which is significantly more wattage than many inverter generators currently on the market. However, the runtime of this generator is severely capped when running on gasoline – the runtime is just 7.5 hours at 25% load, the worst of any generator we reviewed. The culprit isn’t the fuel tank, which is 1.6 gallons, but rather poor fuel efficiency from the large 192cc Champion engine.

That said, this generator offers a nice array of outlets, including not just the standard 120V three-prong outlets but also an RV-ready 120V twist-lock outlet. It also has an electric starter function, which many users appreciated as a way to bypass pulling repeatedly on the recoil starter.

When it comes to noise, this inverter generator is in the middle of the pack. It is rated for 59 dB of noise, which users advise is a minimum noise level – the generator will be somewhat louder during most uses.

Pros
  • Dual-fuel inverter generator
  • 3,400 watts of surge power on gasoline
  • Includes RV-ready outlet
  • Three-year warranty
Cons
  • Very short runtime with mediocre engine fuel efficiency
  • Moderately noisy

This 3000-watt inverter generator from Wen is the ideal companion for a medium-sized RV thanks to its power output, portability, and range of outlets. The generator features a sizable 212cc four-stroke OHV engine that is impressively fuel efficient even when running at higher loads. The engine is capable of producing up to 3,100 watts of surge power or 2,800 watts of continuous power, which is more than enough to power all of the appliances in most RVs and still have power leftover.

The fuel tank is somewhat large at 1.85 gallons, which contributes to the overall bulk of this generator. However, it also allows the generator to offer a 7.5-hour runtime at 50% load, which is significantly better than many other inverter generators that are limited in how long they can operate on a single tank.

The generator weighs in at 81 pounds, which can make it somewhat heavy to transport around or move in and out of an RV. However, it does have a pair of small wheels that work well on relatively flat surfaces like around a campground. The generator panel includes an RV-ready twist-lock outlet to make plugging in your RV simple, and there are even two USB charging ports for small electronics.

The noise output of this generator is moderate, ranging from 57 to 63 dB depending on the amount of power you are drawing. While this can be a bit much for a campsite at night, it is significantly quieter than any comparable conventional generator, and you will have to spend a lot more to find a comparable generator that produces less noise.

Pros
  • Enough power for most RVs
  • Includes RV-ready outlet
  • Long runtime of 7.5 hours at 50% load
  • Relatively quiet

VIEW ON AMAZON

This powerful inverter generator from Champion boasts the highest maximum wattage of any generator we’ve reviewed, at 4,000 watts. The continuous power output isn’t far behind at 3,500 watts, making this the generator of choice when you want to reap the benefits of an inverter generator without giving up on the high power output found on comparable conventional generators.

Unlike most of the other inverter generators we reviewed, this generator is not designed with portability in mind at all. The generator weighs 81 pounds and does not have a set of wheels, so you’ll either have to buy the wheel kit separately, or you’ll need two people two carry it by the handles on the steel frame.

The runtime on this generator is impressive given the power – 17 hours at a 25% load – thanks to the extended runtime feature built into the generator. However, while that feature helps with fuel efficiency, the real secret behind the long runtime is the 2.9-gallon fuel tank. So, you should expect to put extra money into fuel for this generator compared to other inverter generator models.

Given its power output, the 64 dB noise rating on this generator is extraordinary, especially when compared to conventional generators with a similar output. RV owners will be glad to find that this generator comes with an RV-ready twist-lock outlet, although storing the generator on a small- to moderate-sized RV can be problematic. That said, the power output and RV outlet make this a terrific choice for larger RV’s where the low noise level sets this generator apart from the competition.

Pros
  • 4,000-watt surge power output
  • Long 17-hour runtime at 25% load
  • 64 dB noise level is impressive given power
  • RV-ready outlet
  • Three-year warranty
Cons
  • Large and heavy, with no wheels
  • Not fuel efficient
  • Lacks electric start

VIEW ON AMAZON

This compact inverter generator from Westinghouse is a versatile model that boasts a moderate power output and quiet engine. The generator is capable of producing up to 2,500 watts of surge power and 2,200 watts of continuous power with the 98cc four-stroke Westinghouse engine. While the engine itself is relatively fuel efficient, beware that the runtime is relatively short due to the small one-gallon gas tank. The generator runs just 10 hours at a 25% load. Especially given the modest power output of the generator, it is easy to climb to 75% load with just a handful of appliances and run through the fuel tank in just a few hours.

That said, the small fuel tank allows this generator to be extremely small in size. Given that it also weighs under 50 pounds and has a molded carry handle built into the top of the shell, the generator is extremely portable. The generator is also quiet, producing just 52 dB of noise at base power draw. Unfortunately, the generator does not have an RV-ready outlet, so there is a more limited user base of campers who will be able to use this generator and take advantage of the quiet engine.

The generator also lacks additional features like an electric start, although it does offer a pair of USB charging ports to make it easy to charge small electronic devices. Residential users receive a three-year warranty on the generator, although this is reduced to only one year for commercial users. However, users found that the Westinghouse engine is extremely reliable over several years of use.

Pros
  • Compact and lightweight
  • Relatively quiet engine
  • Three-year warranty for residential use
Cons
  • No RV outlet
  • Only one-year warranty for commercial users
  • Very short runtime

VIEW ON AMAZON

This inverter generator from Generac is ideal for applications where portability is at a premium and power demands are modest. The generator has a small 80cc OHV engine that produces a maximum of 2,200 watts and can continuously output 1,700 watts. While that might be enough for the needs of a field site or medium-sized RV, it’s important to recognize that this will also mean you will be frequently running the generator near its rated power.

That is particularly a problem for the runtime of this generator, which is limited by the inefficiency of the engine at higher outputs and the limited 1.2-gallon fuel tank. The generator runs for just 10.75 hours at a 25% load, similar to the Westinghouse generator, and so may be limited to just a few hours of runtime in many applications.

That said, the panel of this generator is nicely equipped with a pair of 120V outlets, a single USB charging port, and a 12V DC outlet for charging batteries. All outlets are grounded and can be quickly and easily reset in case of a surge. In addition, the generator is lightweight, at just 47 pounds, making it easy to transport wherever you need it. While the noise level of this generator is not rated, users found that it was comparable to competing inverter generators in the same power range, making it a quiet generator.

The warranty on this generator is somewhat short compared to competitors, at just two years for residential users and one year for commercial users.

Pros
  • Includes 12V DC outlet and USB port
  • Lightweight and portable
  • Grounded outlets with easy reset
Cons
  • Short one-year warranty for commercial use
  • Short runtime due to small fuel tank

This inexpensive inverter generator from Pulsar is an ideal choice for anyone on a budget who still wants the benefits of an inverter generator. Of course, that lower price comes in part because the engine of this generator is smaller than other inverter generators – the 80cc four-stroke OHV engine is capable of producing a maximum of 2,000 watts of surge power and 1,600 watts of continuous power.

However, don’t let the modest power output and price distract you from the performance of this inverter generator. The 1.2-gallon tank and efficient engine allows this generator to operate for up to six hours at a 50% load. The 59 dB noise level is somewhat high given the small size of this generator, but is still not so loud as to be problematic. The design of the generator is compact, and it weighs in at just 47 pounds, so it should be easy for a single person to carry this generator around.

The generator panel has everything you need for everyday use, including a pair of 120V three-pronged outlets, a 12V DC outlet for charging batteries, and a USB port for charging small electronics. The only other reflection of the modest price of this generator is the warranty period, which is limited to just one year regardless of whether you are a recreational or commercial user.

Pros
  • Inexpensive inverter generator
  • Compact and lightweight
  • Relatively long runtime
Cons
  • Short one-year warranty
  • Limited power output
  • 59 dB noise level is loud for the size

Buying Guide

Now that you’ve learned more about our eight favorite inverter generators on the market today, how do you choose between them to find the generator that’s right for you? And why might it be worth spending extra money on an inverter generator instead of opting for a conventional generator? Our buying guide will answer these questions and cover everything you need to know about finding the right inverter generator for your needs.

Inverter vs. conventional generator: What’s the difference?

035_Wellcross_Yamaha_generatorBoth conventional and inverter generators convert a fuel – typically gasoline or propane – into usable AC (alternating current) electricity. However, whereas conventional generators produce AC electricity in one step, inverter generators do it in three steps. Inverter generators use their engine to produce AC electricity, but then convert it to DC (direct current) electricity and then back to AC electricity.

Why go through all this work? One of the biggest reasons is that converting AC power to DC and back cleans the electrical current, smoothing out the energy so that there is far less distortion. Basically, this means that the electricity coming from an inverter generator is less likely to cause miniature power surges that could damage your sensitive electronics, such as computers and smartphones. Conventional generators, on the other hand, produce “dirty” AC electricity that is only suitable for heftier circuits like those found in appliances and power tools.

Inverter generators also offer a number of other benefits over conventional generators.

Inverter generators are typically built with engines that are the fraction of the size that is needed in a conventional generator to produce the same amount of power. That means that inverter generators can be extremely compact and lightweight for portability and storage, but still pack the electric punch you need to power all your stuff.

On top of that, smaller, more efficient engines allow you to spend less on fuel to power your generator. You’ll also get longer runtimes for the same amount of fuel, although the exact runtime of an inverter generator compared to a conventional generator also depends on the size of the fuel tank – because inverter generators are compact, they often have fuel tanks only a few gallons in volume.

Another major advantage that converts many users to opting for an inverter generator over a conventional generator is that inverter generators are comparatively quiet. Inverter generators can be as quiet as 48 dB like on the Honda generator, and nearly all of the inverter generators we reviewed are less than 60 dB. Compare that to noise levels typically well over 60 dB for conventional generators, and it’s easy to see why inverter generators can be preferred in many situations.

With all those advantages in mind, there are a few drawbacks to inverter generators. Inverter generators are almost always more expensive than conventional generators in the same size class because of the newer technology they offer. More concerning, inverter generators can be much more difficult and costly to repair than conventional generators because of the complexity of the microprocessors coupled with the engine.

In addition, inverter generators are often limited in the amount of power that the most heavy-duty models can offer – for example, the most powerful inverter generator we reviewed, the Champion Power Equipment 100302, maxes out at 4,000 watts of power. On the other hand, portable conventional generators with maximum outputs well above 10,000 watts are available. That said, multiple inverter generators can be hooked up in parallel to increase your total available power, which is something that you cannot do with conventional generators.

How much power do you need?

Honda+EU2200i+Tailgating+Carry+11+RGBOnce you’ve decided on an inverter generator, one of the most important considerations you’ll need to decide on is how much power you need. Generators have two power ratings: the maximum, or surge, power, and the continuous, or running, power. The surge power is the amount of power the generator can sustain for several seconds in order to allow motor-driven appliances, like refrigerators, freezers, and even some power tools, to start up. The running power is the amount of power that you’ll be able to draw from the generator over its entire runtime.

The simplest way to figure out how much power you need is to add up the wattage requirements of everything you want to power. This sum needs to be less than the rated running wattage of the generator, and typically it’s a good idea to leave yourself some breathing room. When in doubt, there are a number of online calculators that can help you estimate how much power common appliances draw.

Remember to leave some extra power for charging electronics as well, since this is a possibility with your inverter generator.

Most inverter generators are limited in the amount of power they supply – the most powerful generator we reviewed, the Champion Power Equipment 100302, offers a maximum of 4,000 watts of surge power and 3,500 watts of running power. However, keep in mind that if you need more power than any single inverter generator can offer, you can hook up two inverter generators in parallel using an after-marker parallel connection kit to effectively double your power.

How long you need to run your generator?

Adding more fuel to your generator can be a time-consuming process, as you need to wait for the generator to fully cool down before you can top off the tank. Thus, runtime is an important consideration if you don’t want to lose power halfway through the project that you’re using the generator for.

The runtime of an inverter generator is typically measured at 25% or 50% load, and decreases as more power is drawn from the generator. Runtime is determined by a combination of the fuel efficiency of the engine and the capacity of the fuel tank (if you’re running on gasoline), which can vary widely between generator models. For example, the Champion Power Equipment 100263 runs for just 7.5 hours at 25% load because of its small 1.6-gallon fuel tank, while the 100302 model has a 2.9-gallon tank and can run for 17 hours at a 25% load.

Generators that can run on either gasoline or propane, like the Champion Power Equipment 100263, may have longer or shorter rated runtimes on propane compared to gasoline depending on the size of the internal fuel reservoir. However, using propane also allows you to extend the runtime dramatically because you can buy a larger propane canister. You can also use a valve to connect two or more propane tanks to your generator, switching between them as one is exhausted so there is no downtime.

Generator noise level

A10ZwMo4XfL._SL7500_

The relatively low noise level of inverter generators compared to conventional generators is one of their major selling points. Inverter generators are typically 10 dB or quieter than conventional generators in the same power output class. With most inverter generators, you can actually hold a conversation within a few feet of the generator and they won’t wake up your neighbors if you are powering your house during an outage. However, inverter generators are not completely silent, so you’ll need to be careful in using them in situations like camping.

The reason that inverter generators are able to be so quiet is that they can actually modulate the amount of work the engine is doing in response to how much power you are drawing from the generator.

Thus, a generator like the model from Honda can scale from just 48 dB of noise at a low power draw to up to 57 dB of noise at maximum power. Inverter generator noise levels also vary a lot from model to model – while the Honda has a minimum noise level of 48 dB, the model from Wen has a minimum noise level of 57 dB.

Safety features

БезымянныйWhile generators are not extremely dangerous compared to other tools, it is advisable to look for inverter generator models that offer built-in safety features.

One major safety feature that most inverter generators have, and most conventional portable generators don’t, is an enclosed engine. This is partly to help reduce engine noise and protect the engine parts from damage during transport, but it also ensures that you can’t burn yourself on any hot exposed engine components.

Another important safety feature that all of the inverter generators we reviewed have is an automatic low-oil shutoff. This shutoff detects whenever the engine oil is dangerously low and powers down the generator before the lack of oil can do any costly and sometimes irreversible damage to the engine as well as cause power surges.

All of the generators we reviewed also have overload prevention built-in. That means that if you exceed the generator’s running capacity (or surge capacity when a motor-driven appliance is starting up), the generator will automatically shut down in order to prevent a power surge or damage to the engine.

Tips and tricks


It’s extremely important to maintain your generator and use it properly in order to keep it running for years to come. Perhaps the most important thing you can do is to ensure the engine is properly oiled, since running low on oil can cause serious engine damage. You should change the oil every 50–100 hours, and possibly even more frequently if you use the generator in dusty conditions or at its maximum power output.

Another important safety tip is that you need to allow the engine to fully cool down before adding gasoline to the fuel tank. Adding fuel to a hot generator is a safety hazard that can present a danger to you as well as potentially cause damage to the engine.

How much do inverter generators cost?

Inverter generators typically cost significantly more than conventional generators in the same size class, but the cost of different inverter generator models can vary quite a lot. For example, the budget-priced model from Pulsar costs less than $400, while the expensive Honda generator is over $1,000. In general, expect to spend between $500 and $900 for a quality inverter generator.

FAQ

How much power your RV requires will depend on the size of your RV and the appliances you are trying to power. You can either sum up the wattage requirements of all the major appliances in your RV, or use an online calculator tool to estimate your power requirements. It’s always a good idea to leave yourself some leeway in this calculation, as it is not exact and doesn’t account for small electronics. Another thing to look for if you will be powering an RV is an RV-ready twist-lock outlet, like that found on the Wen generator.

In general, you cannot run a gasoline generator on propane unless it is a duel-fuel generator like the Champion Power Equipment 100263. Some manufacturers sell after-market conversion kits to convert your gasoline generator to run on propane instead.

Most portable generators are designed so that they do not need to be grounded with a grounding rod. This is because the engine, fuel tank, and housing are all bonded to the generator’s frame. However, the best way to be sure is to check the manual for your generator.

Wrap-up

Our three overall favorite inverter generators on the market today are the Yamaha EF2000iSv2, the Honda EU2200i, and the Champion Power Equipment 100263. The Champion generator is set apart from the competition in that it is one of only a limited number of dual-fuel inverter generator models, meaning that it can run on either gasoline or propane. The ability to run on propane makes it a great choice for saving it for a power outage at home. The Honda generator is the quietest inverter generator we reviewed and offers incredibly reliable performance thanks to the Honda engine, but that brand name does come at a significant price premium. We feel the Yamaha generator is the overall best inverter generator on the market today thanks to its impressive combination of power, portability, price, and quiet operation. Plus, the Yamaha generator comes with a three-year warranty so you can be confident that you’ll be using the generator for years to come.
