Champion 4000-Watt RV Ready Inverter Generator | Quiet Technology & 3-Year Warranty

Lightweight, RV-Ready Power On the Go

Meet the Champion Power Equipment 100809 4000-Watt Portable Inverter Generator with CO Shield. Weighing under 49 pounds, it is one of the lightest 4000-watt inverters, designed for campers, tailgaters, and RV enthusiasts who want dependable power without the bulk. The 149cc Champion engine delivers 4000 starting watts and 3000 running watts, while the 1.54-gallon tank supports up to 10 hours of operation at 25 percent load, depending on conditions.

Quiet operation matters. This inverter runs at 64 dBA from 23 feet, a level that blends into outdoor settings while keeping conversations and coffee pots undisturbed. You also get clean power with less than 3 percent total harmonic distortion, which helps protect sensitive electronics during charging or powering essentials.
