Technocel has just rolled out its latest device, the Sprint Battery Boost which is actually a portable recharging solution that doubles up as microSD memory card reader, catering for most of the gadgets out there such as cellphones, Bluetooth headsets and devices that come with a micro USB port. The Sprint Battery Boost itself has a 600 mAh lithium ion battery that can offer up to another hour of talk time on your handset on average, while its microSD memory card slot reader lets you store and transfer data files such as photos, documents and music files on-the-go. It can be juiced up when connected to any powered USB port, and thanks to its built-in carabineer clip, you can always keep it close to you wherever you go.
