Run or charge a DVD player, laptop computer, digital camera, small power tool, or any mobile device that uses up to 160 watts of power in your vehicle or boat with the CPS160SU-DC Power Inverter by CyberPower. Plugged into your car's DC outlet/cigarette lighter socket, the inverter converts your car battery's 10.5-15.5 VDC output to 120 VAC, producing a steady 120W of power and peak surge power of 160W. Along with the three-pronged AC outlet, the inverter features a 5 VDC, 2.1A USB port and a cigarette-lighter style DC power socket. Surge protection guards your device's circuitry, and the unit will shut down automatically if the voltage of your car battery falls below 10.5 VDC.
