| Summary | The Briggs & Stratton 30728 Storm Responder is a 6250-watt gasoline generator built for homeowners and job sites that need sustained power for essential appliances and tools. With 8500 peak watts, it can start large loads like air compressors and refrigerators that draw high inrush current. The 7.5-gallon fuel tank delivers 11 hours of runtime at half load, meaning users can run the unit through a full workday or overnight without refueling. This is a stationary-leaning portable unit, not a grab-and-go machine. | The Genmax GM6000XiE is a 5250-watt inverter generator built around a 312cc OHV engine. It delivers 6000 watts at startup, enough to handle the initial surge of refrigerators, air compressors, and power tools. The inverter produces less than 3% THD, meaning laptops and phones charge safely. At 106.9 lbs with wheels included, it sits between grab-and-go portability and serious job-site power. |
