Powered by a 20HP Honda GX620 engine, this generator has an output of 12000 watts surge power, and continuous 10.8KW. The 15-gallon fuel tank and fully loaded receptacle panel will keep a work crew busy all day without re-fueling or waiting for a power receptacle to free up. Standard features include switchless full power, automatic idle control, hour meter, and a four wheel all-terrain dolly kit. This model is complete with a 12 volt battery and Roofmaster's Non-Flat Lite(NFL) tires for a flat free job site workhorse. Remember, the NFL tire does not have a "memory" or flat spot after sitting overnight.
