Best Inverter Generators: Compared by Use

An inverter generator produces power that is cleaner and steadier than a conventional open-frame unit, and most are quieter and lighter for their output. The trade is price and, on larger machines, weight. This guide compares the inverter generators in our comparison tool using manufacturer figures retrieved on 2 November 2026. We rank by use rather than naming a single winner, because the right one depends on what you plug in.

Best by use

Lightest for camping and tailgating

The Honda EU2200i (46.5 lb) and the Champion 100809 (48.1 lb) are the lightest in our list, and the Champion carries a higher rating at 3,000 running watts. The EU2200i and Yamaha EF2200iS are rated at 1,800 W and both support parallel connection to combine two units. The Champion 100809 lists a CO sensor shutdown and parallel capability.

Best for RV and essential circuits

The 3,000 to 3,900 W class covers a fridge, lights, a furnace fan and many RV loads. The Champion 201050, Generac GP3500iO, Predator 3500 and Westinghouse iGen5000DF sit here. The 201050 and the iGen5000DF run on two fuels. The Predator lists electric start and CO shutdown. The iGen5000DF adds remote start. Add up your loads first with the generator load calculator.

Best for the quietest running

Among the figures makers state, the Westinghouse iGen5000DF is listed at 52 dBA and the Honda EU7000iS at 52 dB at 1/4 load. The Honda EU2200i lists 53 dB at 1/4 load. Makers measure at different distances and loads, so treat these as a guide and read the footnotes on the manufacturer page.

Largest inverter in our list

The Honda EU7000iS is rated at 5,500 running watts and weighs 263.2 lb. Honda’s page did not state its start type, engine size or warranty in the sources we reviewed, so those cells show Not stated.

What to look for in an inverter generator

• Running watts, not peak. Peak lasts seconds. Size to running watts plus your largest starting surge.
• Total harmonic distortion (THD). Low THD matters for laptops and other electronics. Most makers do not publish a THD figure, so the row in the tool often says Not stated.
• Parallel capability. Lets you link two small units to double the output.
• CO shutdown. A sensor that shuts the engine down if carbon monoxide builds up. It adds a margin of safety but does not replace running the generator outdoors.
• Runtime on a tank. Compare runtimes at the same load. The tool shows each maker’s stated load.

What we could not verify

Only the Predator and Westinghouse listings show a price. The Predator weight of 102 lb came from a listing summary and was not confirmed against the manual. Honda blocked our automated fetch, so check its page for the latest EU2200i and EU7000iS figures.
