Our take on the Yamaha EF2200iS with CO Sensor

The Yamaha EF2200iS is a portable gas inverter generator with 2,200 watts peak and 1,800 watts continuous output. It stands out for its CO sensor that shuts the unit down when carbon monoxide builds up, plus Smart Throttle fuel savings, a standard RV outlet and a tool-free maintenance panel. At $799.99 at eBay as of November 5, 2026, it sits at the low end of its recent range across six stores.
