With power output designed to mirror a pure sine wave . this generator limits total harmonic distortion to under 0.3 percent at no load and under 1.2 percent at full load . making it safe to run laptops . cellphones . monitors . tablets and other sensitive electronics. The ultra-efficient one-gallon tank provides over 6 hours of half-load run time. The fully-packed panel comes equipped with two three-prong 120V 15A NEMA 5-20R receptacles and two 5V USB ports. Maximize fuel economy by engaging the eco-mode switch. This allows the generator’s engine to automatically adjust its fuel consumption as items are plugged into and unplugged from the panel . preventing the unnecessary usage of gasoline.
