| 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 PREDATOR® 6500 Watt Portable Generator is designed for home backup during emergencies and powering tools at jobsites. It features a 301cc gas engine, GFCI outlets, and CO SECURE® carbon monoxide shutdown for safety. |
