Product Description:
TekCharge MP1550 takes advantage of AA batteries to provide emergency power to popular mobile phones, plus many more small portable devices. Because TekCharge uses alkaline or rechargeable AA batteries, you'll never be without power again--even on the road. TekCharge also doubles as a battery charger for your rechargeable AA batteries, so you can stay green while staying charged.
TekCharge charges and powers portable devices--anywhere, anytime--making it a versatile solution for the power needs of most of your mobile products, on the road, and at home. Often, portable devices are in need of recharging after a few hours of use. With TekCharge, you can enjoy hours of extended play time on your mobile phones, smart phones, PDAs, iPhone, iPods and MP3 players, portable CD players, Bluetooth headsets, and other small portable electronic products.

TekCharge connects to your device in two ways: First, you can use an adapter to connect to your device; or second, you can use your USB device cable, bypassing the need for an extra adapter. The device also features a voltage regulator so it won't harm your device or its battery. TekCharge comes with a handy tote, plus seven adapter tips for connection to:

-Blackberry (mini USB)
