The (PS-2000) Royal Power 2000 Watt 12 volt dc to 120 volt ac puresine wave power inverter takes direct current from a car, truck, boat or free standing battery system and inverts it into standard 120 volt household alternating current. With under 3 percent of harmonic distortion this pure sine wave dc to ac power inverter can run all different types of sensitive electrical equipment. This inverter includes three outlets that can handle the full load of the 2000 watts through any outlet. The steel reinforced columns inside and outer mounting plate make this inverter ideal for mobile applications.
