It has electric start and large fuel tank so you can run it many hours at moderate load without constant refueling. Frame is reinforced steel, with lifting eye for easier transport or securing on uneven terrain. It delivers low harmonic distortion, which helps with sensitive electronics or motors. Diesel units are generally more fuel-efficient under heavy loads compared to gasoline.
