The CPI 200 CH 200W DC-to-AC Power Inverter takes low voltage DC (direct current) power from your automobile or other low voltage power supply and converts it to standard 110 volt AC (alternating current) power like the electrical current you have in your home. Simply by plugging it into your vehicle's cigarette lighter socket, you can use many of your household appliances and electronic products in automobiles, RVs, boats, tractors, trucks, and virtually anywhere else.
