There are about a zillion portable cell phone battery chargers on the market, so what do you do to stand out? The folks over at Technocel have made their very own portable charger extra special by throwing in a MicroSD Card reader. Their new Sprint Battery Boost is a portable recharging solution and Micro SD card reader all-in-one for your mobile phone and other micro-USB devices. It can add up-to 1 hour of additional talk time to a phone and also features a built-in carabineer clip. This accessory is hardly cutting edge, but if you need to carry along a battery boost with you, you might as well get one that has another trick up its sleeve. The Sprint Battery Boost retails for $29.99 and is available at Sprint Stores and online.
