| 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 WEN 56877-CA is a 7000-watt gasoline generator built to handle both steady power and high-demand startup surges. The 9000-watt peak capacity means it can start air compressors, well pumps, and air conditioning units that draw 1.5 to 2 times their running wattage on startup, then settle into continuous operation at 7000 watts. This power band covers most household circuits, power tools, and small job site equipment simultaneously. The 6.5-gallon fuel tank runs for 9 hours at 50 percent load, which translates to roughly 18 hours at 25 percent load for lighter duty cycles. A 2-year warranty backs the unit, giving owners a defined service window for defects. |
