The Duracell 175W pocket inverter converts 12-volt DC battery power from a vehicle into up to 175 watts of usable AC and USB electricity. This sleek, compact adapter includes a three-prong household AC outlet and a fast 2.1-amp USB charge port, allowing you to operate and recharge a larger range of mobile devices. The pocket inverter is powerful enough to handle higher-output electronics such as a TV/VCR combo or work light, and can simultaneously run and charge both an AC and USB device at once, including iPads/tablet PCs, laptops, netbooks, e-readers, smartphones and many other devices for ultimate charging convenience. The Duracell pocket inverter is ideal for any purpose, from your mobile computing to recreational use. As one of the smallest inverters on the market, it stores easily in your laptop bag, vehicle console or glove box, and its advanced cooling technology ensures a perceived noise level that is up to 50 percent quieter.
