After conducting extensive research into what our customers really want in a portable generator our conclusions were no surprise. Our extensive research indicated you want more power, bigger fuel tanks, longer run times, and excellent customer support. We engineered our generators with these customer desires in-mind by providing independently certified, industryleading power output. We increased our fuel tank sizes to be over 25% bigger than our competition in every category. Bigger tanks means longer run times; 12-14 hours on every gen without refueling!
