| 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 Honda EB6500X is a 5500-watt gasoline generator built for job sites and extended outages. Its 6500-watt peak output handles large equipment startups, while a 6.2-gallon tank delivers 9.8 hours of runtime at half load. The recoil start and included wheel kit make it mobile, though at 215.8 lbs it requires planning for transport. |
