| Summary | 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. | The RYOBI RY906522 is a gasoline-powered portable generator delivering 6800 running watts and 8500 starting watts, featuring a 420cc OHV engine and a 6-gallon fuel tank for up to 9 hours of runtime at 50% load. |
