The Prong PocketPlug case makes charging your iPhone infinitely more convenient. All you have to do is slide your phone into the case, pull out the prongs, and plug it into an outlet. The case is specially convenient when you’re travelling since there are no more docks, chargers, or wires to deal with.
The disadvantage is that you won’t be able to use your phone comfortably while it’s charging, since it’s attached upright on the socket. If you prefer corded charging, then you can tote along your wire since the case has a micro USB port on the side.
The case doesn’t have a battery built into it, but that might be in the works for future versions, as Prong specifically addresses this in their FAQ: “The current version of the PocketPlug is an AC charger only and does not include an extended battery.” The PocketPlug comes in iPhone 4/4S and iPhone 5 versions, which retail for $59.95 Buy it now
