Tekkeon TekCharge MP1580 Mobile Power Pack & Battery Charger

The Tekkeon TekCharge MP1580 Mobile Power Pack & Battery Charger uses either two or four AA batteries to provide an extra boost of juice for pretty much any USB powered mobile device on the market including iPod, iPhone, eReaders, smartphones, GPS devices, MP3 players, mobile phones and even digital cameras and camcorders. The TekCharge works by connecting to your device with the USB cable that came with it, or by using the TekCharge's included micro and mini USB adapters to plug directly into your device. Plus, there's a voltage regulator, so the TekCharge won't ruin your USB device or its battery. If the extra adapter you need for your device isn't included, Tekkeon offers plenty of additional adapters (sold separately). The TekCharge even works as a battery charger, so if you use rechargeable NiMH or lithium AA batteries, the MP1580 will charge them for you.
