Producing up to 11,400 starting watts and 9,200 running watts on gasoline, this high-capacity generator is built for home backup power, demanding job sites, farms, and large outdoor events.

Electric start ensures quick, effortless operation, while the rugged design and cast iron sleeve provide long-term durability under heavy workloads.
