The Battery Boost is a portable battery pack that will charge your handset, Bluetooth headset, mobile hotspot, mp3 player, and just about any other device that has a micro USB port.
It can give you up to an hour of additional talk time,* the Battery Boost also doubles as a micro SD card reader.**
It lets you access to all kinds of digital media for access whenever you need it most.
When the Battery Boost is placed within ANY USB port such as a computer, home or car charger, it will automatically charge its internal battery.
It will even charge the internal back up battery AND your handset at the same time!
All pretty cool, if only the iPhone and iPad came ith a micro USB port we'd be sold. What we need is a move to standardize electronic device chargers like is going on in the EU.
