A week ago, the audience KickStarter supported the production of one of the most interesting cases for iPhone. zest JuiceTank lies in the fact that in this case is built to charge the phone.
The problem, when the iPhone is about to be discharged, and there is no power adapter, faced many handy. Including JuiceTank authors. They offered an interesting design solution: Integrated Charging directly for iPhone. Durable case will not only protect the device from damage, but will charge the phone just about anywhere where there is a simple socket.
Paste iPhone into the socket is possible in both positions - in horizontal and vertical. Please note that the plug is in the normal state is hidden, it will only appear when the phone user presses the dedicated button cover.
The main "flaw" is that JuiceTank supports only standard socket NEMA 1 (USA, Canada, Japan). The developers are currently working hard to add support for other standards. In future versions of the cover may appear and built-in battery. And then JuiceTank will be a real "Masthev" for travelers.
