Fill her up, more juice for your iPhone

As anyone who uses their iPhone to take, edit and upload photo's in the field will tell you, the iPhone's battery will not last for a full days shoot. The good news is there are a number of solutions out there to fix this problem, from external batteries that with charge your iPhone when its battery has died, to ergonomically designed, form fitting case styles power packs like the MiLi, which I reviewed last month. For me it is this case style battery pack that I find most useful, as the iPhone first powers itself from these battery packs, and then switches to its own internal battery when the power packs had died, and so you can keep shooting, uninterrupted for twice as long as normal.

As this market is growing, I have decided to compile the current case style battery packs, but if I missed any, then please let me know.
