Inverter generators are known for being slightly pricier than conventional generators, but this is not unwarranted; these machines are notoriously quieter, more efficient, and longer-lasting than non-inverter models.
Whether you're looking for a good generator to provide power for RV and road trips, or as a backup for home power outage emergencies, an inverter generator will cover your needs and then some.
We've found some of the best inverter generators available to buy but before we delve into our top 10 list, let's briefly cover exactly what an inverter generator is and what sets these machines apart from the herd.

In order to understand what an inverter generator is, we have to briefly cover what a regular generator is and how it works. In addition to the actual electric generator, conventional generators also house an internal fuel-driven combustion engine which is why they are understandably on the huge side.
The Best Inverter Generator—Summary
While these generators do a good job of producing high-quality electrical output, they do struggle somewhat when powering appliances with different watts, many appliances at once, or when switching from one to another.

How to Pick the Best Whole House Generator for Your House
- During this "transitional" period, the electricity produced isn't as high-quality as it could be, and many have reported blown appliances and devices (and wished for super-human strength so they can throw their generator into a river).
- What's more, since these generators run at the same speed all the time—this is, in fact, the most fuel-efficient way to run a generator—they are rather on the noisier side.
- An inverter generator doesn't have a separate engine and generator; it combines these two parts into one machine, making it much lighter and compact.
- Inverters work by taking AC power, breaking it down to DC power, and then building it back up to controlled, stable, and high-quality AC power again.
These generators have lower speeds, are less noisy, and pretty much burn the same amount whether running on high or low.
Put in the simplest terms possible, an inverter is like a regular generator but with intuitive functionality that gives the exact amount of power that you require from it at any given moment instead of running at full throttle all the time.
However, if budget is your only concern when it comes to selecting a generator, according to Jesse Gorter of Solar Solutions, a renewable energy engineer, and previously the Energy Officer for the United Nations, your inverter generator could end up burning the same amount of fuel as a conventional generator depending on how you use it.
"The inverter generator will give you a great advantage over the conventional generator when you're looking at the fuel costs under varying loads," he explained.
"If you're using your inverter generator under full load, and you're comparing it to your conventional generator under full load, then they produce kind of the same amount of noise and consume the same amount of fuel; it's just that the inverter generator can possibly produce a little bit of a higher quality electrical output."
In addition, he added that turning off the inverter generator's eco-throttle mode is akin to reducing it to a conventional generator, as you have lost all the advantages the inverter offers, so, in this instance, it might not be worth your while to splash out on an inverter when a regular generator will do.
That being said, we have found 10 of the best inverter generators with a bunch of handy features like electric start, remote start, and super-quiet functioning, starting from as low as US$399.
Our top picks for the best inverter generator available to buy now on Amazon are:.

Best Inverter Generators for 2022
Westinghouse WH2000iXLT | 2200W Inverter Generator
I’m a big advocate for inverter generators over traditional gas models because they have many practical advantages over traditional gas models, unless you need to power your entire house, in that case you might need a powerful 12,000W generator, but inverter generators are getting more powerful ever year, like the DuroMax XP9000iH (9000W).
In a nutshell, an inverter generator takes standard AC current, converts it to DC, then converts it back again to stable AC power. In the last phase, the AC power is digitally converted to true sine wave clean power, capable of safely powering sensitive electronic devices.
The term “inverter” comes from this process of inverting AC to DC to AC. A traditional gas generator creates “dirty” electricity, producing voltage spikes, which can damage sensitive electronics, like laptops and advanced power tools.
How Does a Generator Work?
Technology keeps moving forward, and ultimately you, the consumer, benefits by getting more for your money.
I have one important point I want to make before you spend your hard-earned money on an inverter generator — don’t buy a no-name brand model. No-name brands are great for a lot of products like toilet paper, USB cables, towels, etc., but I don’t recommend a generic brand inverter generator.
You’ll probably find a lot of cheap inverters from brands you’ve never heard of, but I’d advise you stay away from them for several key reasons.
