Our take on the Generac GP6500 6500-Watt Gasoline Powered Portable Generator

The Generac GP6500 is a gasoline-powered portable generator that delivers 6,500 running watts and 8,125 starting watts, enough to power a home's essentials during an outage or run power tools on a job site. Its PowerRush technology provides over 40% more starting capacity than comparable generators, helping it start large loads like air conditioners and well pumps. The 7.9-gallon steel fuel tank gives up to 10.5 hours of run time at 50% load, and features like low-oil shutdown and an hour meter add convenience. Owners praise its reliability and easy starting, though some find it heavy and noisy.
