| Summary | The Genmax GM9000iE is a 7,600-watt gasoline inverter generator built around a 458cc 4-stroke engine. It delivers 9,000 peak watts for starting large appliances like air conditioners and refrigerators, then sustains 7,600 running watts for simultaneous multi-device operation. The inverter topology keeps total harmonic distortion at 3% or below, protecting laptops, TVs, and other sensitive gear from electrical damage. | The RYOBI RY906522 is a gasoline-powered portable generator delivering 6800 running watts and 8500 starting watts, featuring a 420cc OHV engine and a 6-gallon fuel tank for up to 9 hours of runtime at 50% load. |
