The Generac GP3000i is a portable inverter generator rated at 3,000 starting watts on gasoline, with a 1.1-gallon tank and four outlets. It runs quiet enough for campsites and tailgates and is clean enough for sensitive electronics like laptops and phones. The best new price is $749 at Northern Tool as of November 3, 2026, with five stores listing it new. That sits at the low end of what this class of 3,000-watt inverter generator typically sells for.
