The issue with old-school generators is that they always operated at full bore, burning fuel and pumping out power at the highest possible capacity at all times, but inverter generators solve the problem. They offer a throttle that adjusts engine speed to meet actual electrical needs. This greatly improves fuel efficiency, reduces emissions, and decreases operating volume. Inverter generators also provide an extremely clean source of electricity that won’t harm sensitive devices with unpredictable and inconsistent power output. The best inverter generators offer solid efficiency and runtime, rock-solid craftsmanship, and deliver the reliability you need when the lights go out.

How we picked the best inverter generators
As a tech enthusiast and camping addict, I’ve looked at a wide range of mobile power products for the likes of Popular Science, Scientific American, The Daily Beast, and more. I’ve researched each of these selections extensively via a combination of first-hand trials, input from experts, and reviews from real-world consumers. We focus on generators that offer solid build quality, powerful performance, and reliability. A generator isn’t worth much if you can’t be sure it will work when you really need it.
What to consider when buying an inverter generator
There are a lot of inverter generators out there, but they tend to come with lofty price tags. It requires hardware to actually invert the current, which allows it to avoid voltage spikes that could harm devices plugged into it. Many subpar brands simply don’t offer the build quality that you would expect from such a high-value piece of equipment, while others fall short of delivering the performance you need for reliable power. To make a smart buy, here are a few important considerations to keep in mind so that you can be sure of getting the best inverter generator for the money:
Power output
If a generator doesn’t produce enough power to meet your needs, what good is it? Generators are rated by the number of watts they can produce in any given moment, which is often accompanied by a peak performance rating that represents the maximum power they can deliver in short bursts. To determine how much juice you need, add up the operating wattage for all the devices and appliances you expect to power, then find a generator that delivers accordingly. The average 5000-7500W generator, for example, will generally provide enough power for most of the key items in your home, including the fridge, TV, lighting, well pump, and a smattering of small devices.
Runtime
If you expect to be using your inverter generator for long periods at a time—if you live somewhere with frequent or prolonged power outages, for example, or if you’ll be needing off-grid power all day long—you don’t want to be refueling it again and again. Runtimes are determined by how large a generator’s fuel tank is combined with its operating efficiency. Most inverter generators have runtimes of roughly 5-6 hours, though a few highly efficient models can stretch that to nearly a full day.
Fuel type
While the majority of inverter generators run on gasoline, many also run on propane or natural gas, and a few can even be powered by the sun. Gas offers the most power output but it’s also the loudest and causes the most emissions. Propane and natural gas shave off a bit of the output in favor of quieter, cleaner operation. Solar generators are emission-free and just shy of silent, but they can only be recharged if the sun is out (or a wall/car socket is handy).
Size and weight
Inverter generators come in a variety of sizes and weights, resulting in varying degrees of portability. Some are large and essentially immobile, which means they’re designed to be set in place and forgotten about until the need arises. Others are more portable thanks to reduced size, weight, or the addition of handles and wheels.
Reliability
A generator doesn’t do much good if it breaks down when you need it. Reliable craftsmanship is essential, but it can be difficult to determine at a glance or by reading a spec sheet. We’ve verified the reliability of our picks via reviews from owners who have used specific models over time.
The best inverter generators: Reviews & Recommendations
Our top-rated inverter generators represent a range of uses and budgets. Some are designed to provide full-fledged backup power for an entire home.

When it comes to building an inverter generator that delivers a lifespan worthy of the investment, Generac is as good as they come. The GP3500iO is built to last and will provide many years of reliable power.
Speaking of which, its power output is no slouch either. While its 3,000-3,500W operating range isn’t large enough to keep an entire house powered, it is more than enough to keep key appliances operating or to keep a campsite, RV, or off-grid worksite fully electrified. It’s also parallel-ready, so if you do need more power you can chain a second unit in to double the output. And at a surprisingly competitive price of just over $800, buying two isn’t all that much of a stretch.
It’s 50% quieter than most comparably sized generators, making it perfect for hauling out into nature. That being said, it’s a bit lighter than many similar models, it isn’t exactly featherweight and it doesn’t come with wheels, so some may find it somewhat challenging to wrangle in and out of the RV.
For all intents and purposes, however, we think the GP3500iO is the best inverter generator for the money thanks to its outstanding build quality, performance, and versatility.

FAQs
Q: What is best, an inverter or a generator?
An inverter is a component in an inverter generator that converts AC power into DC power and then “inverts” it back into cleaner AC power. That might sound technical but the important thing is that it results in power that is “safer” for sensitive devices like laptops or smartphones, and it throttles the engine to match your actual power demands, which improves a generator’s efficiency.
Q: What is the highest-watt inverter generator?
While industrial-grade inverter generators can get quite large, the highest wattage you’ll find at the consumer level is about 15,000-17,500. That’s wildly unnecessary for the typical user. The largest generator we’ve suggested is the DuroMax XP13000HX, which can produce up to 13,000 watts—more than enough for the average home.
Q: What is the most reliable inverter generator?
All of the generators we’ve recommended above offer outstanding reliability. In terms of lifespan, most will last upwards of 10 years with proper maintenance.
Q: Is an inverter generator good for home use?
Absolutely. The “clean” power produced by an inverter generator ensures that all your electronics can operate safely. As long as you buy a model that offers the appropriate level of power for your needs, it is perfectly suited for the task.
Q: How big of an inverter generator do I need?
That depends on how you intend to use it. To power the majority of your home—including a fridge, lights, TV, and a smattering of other small appliances and devices—you’ll want at least 4,000W. If you’ll be camping and powering an RV, shoot for at least 1,800 watts as most RV air conditions require around 1,500W and you’ll want a little leftover for lights and charging your phone.
Final thoughts on inverter generators
If you live in an area where power cuts are frequent, an inverter generator will be a game-changer. It will ensure that you have plenty of reliable power while everyone else on the block sits in the dark. And if you’re looking to power an RV, an inverter generator will keep you living in comfort while off the grid. While the best inverter generators are no small investment, one will pay for itself in the long run in terms of comfort and peace of mind.
