| 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 Generac #7680 GP6500 is a 6500-watt gasoline generator built for job sites and backup power scenarios where sustained mid-range loads matter. Its 8125-watt peak capacity handles motor startup surges, making it suitable for running air compressors, circular saws, and multiple tools simultaneously on a construction site or powering essential home systems during outages. |
