Our take on the Champion 4500-Watt Dual-Fuel Inverter

The Champion 4500-Watt Dual-Fuel Inverter is a portable generator that runs on gasoline or propane and produces clean power with less than 3% THD, making it safe for sensitive electronics. It includes a CO Shield carbon monoxide sensor that automatically shuts the unit off, plus electric start and a recoil backup. With 3500 running watts on gasoline and 3285 on propane, it suits RV owners, campers, and tailgaters who need quiet, reliable power. Competing inverter generators often lack dual-fuel capability or CO detection at this power level, but the Champion is heavier and has a smaller fuel tank than some rivals.
