If you happen to be at SxSW 2012 or dropped by for a while, you might have caught the FedEx human power couriers walking around. These folks are not there to help deliver a package or document, but rather, they walk around, giving opportunities to SxSW 2012 attendees who have gadgets that have run low on battery power. Wearing special FedEx jackets and pants that have been outfitted with mophie juice pack powerstation battery packs, you know for sure that you can let your iPhone run out of juice without missing a beat. It would have been nicer if there were Energizer or Duracell representatives there, as a testament to some of their portable power packs that run on either an internal battery, or use AA/AAA batteries inside. Whatever the case is, always make sure you juice up your smartphones and tablets the night before you head out to the showfloor, it would save you a whole lot of heartache and trouble.
