The Xantrex Technologies XPower Pocket Power Pac 100-watt inverter is the first stand-alone mobile power solution. The Xpower Pocket Power Pack combines a 100-watt inverter with a high capacity, high output battery pack to create a truly mobile power solution. It converts 12-volt DC power from vehicle battery into 115V AC power. So if your laptop battery runs down, or you need five more minutes with your portable DVD player, you can just plug straight into the AC outlet on the inverter and keep working or watching, just like you are at home with the wall plug next to you. In addition to the three-prong AC power outlet, this inverter includes a USB charge port which can power or charge iPod, Blackberry, PalmPilots, and a wide range of other electronic devices. It features a blue LED power indicator; DC cable with a vehicle and airline connector; 3.3 Ah NiMh battery pack; over-temperature shutdown; and low-battery voltage shutdown (10.5V DC and automatic reset). This unit is covered by a 1-year warranty.
