The Portable Power Extender And Inverter.

When no DC power is available, this lightweight device will continue to power laptops for up to two hours, portable gaming systems for 12 hours, and an MP3 player for up to 72 hours. Smaller than a paperback novel, it serves as a supplementary power supply for portable electronics by inverting 12-volt DC from a vehicle battery or airline seat to 120-volt AC, the same kind of power used in home power outlets, but, unlike typical adapters that only provide power as long as they are plugged into a cars cigarette lighter, this one has a built-in lithium battery pack that provides additional power for your devices, even while unplugged. The inverter has a three-prong AC outlet to accommodate all chargers and adapters for mobile electronics and two USB ports for an iPod or other MP3 player. The inverter uses safety monitoring circuitry, a blue LED battery status indicator, and a silent exhaust fan. 5 1/2" L x 3 1/4" W x 1 1/2" D. (1 lb.)
