| 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 Firman P06701 is a 6700-watt gasoline generator built around a 389cc OHV 4-stroke engine with a cast iron sleeve. This wattage class powers essential home appliances, job site tools, and outdoor event equipment simultaneously. The 8-gallon fuel tank stretches runtime to 12 hours at half load, meaning users refuel once per day under moderate use rather than every few hours. At 74 decibels, the noise level matches a vacuum cleaner, loud enough to require distance from neighbors but typical for this power class. The recoil starting system is mechanically simple and reliable, though it demands physical effort on cold mornings or after storage. |
