Inverter generators are a relatively new type of portable generator, but not all models respond well to high power demands. We found some that fail to deliver the promised amount of power when faced with surges.
As a group, inverter generators do better than regular portable generators in almost every way. They typically cost more than portable generators, but inverter generators run longer and use less energy.
Our ratings of dozens of models include the brands you’ll see whether you’re shopping online or buying at home centers or dealers: Briggs & Stratton, Generac, Honda, Predator, and Ryobi. In addition to inverters, you’ll also find traditional gasoline-powered portable generators and home standby generators. Prices for generators in our ratings range from about $350 for a modest one that can power a few key appliances to more than $4,000 for home standby models that can handle everything in your house.
CR members can read on for ratings and reviews of top-rated inverter generators, one from each of the four size categories, followed by two large inverter models to skip. CR members can also dive into our complete generator ratings for even more options. And read our generator buying guide for shopping tips.
As always—and regardless of whether or not you buy a generator with a CO safety shutoff—use a gasoline generator only outdoors, at least 20 feet from your house, with the exhaust directed away from any windows or doors.
Best Inverter Generators
Each of these highly rated inverter generators has CO safety technology designed to stop the engine if carbon monoxide reaches certain limits in an enclosed space, a feature CR considers very important. Each earns very good or excellent ratings in tests of that function.
