The JuiceTank case for iPhone 4 and 4S A really interesting iPhone case design has just hit KickStarter called JuiceTank. In addition to providing some added protection, the JuiceTank has two wall plug prongs which eject with the press of a button, allowing you to charge your iPhone 4 or 4s without needing to carry around wires. With this case and the advent of wireless syncing, there's really not much reason to use the dock connector for anything, eh? While handy, for that amount of added thickness, I would hope that there would be some additional charge stored within the case, and not just an easy way of charging up the iPhone's battery. Of course, it looks like these guys have crammed in a fair bit to their case as is, and the design is admittedly simple and useful. The JuiceTank guys are aiming to raise $125,000 over the next 60 days, and they're already five grand in towards that amount. Assuming it reaches its funding goal, the case should be shipping this summer. If you pitch in $40 now, you can get one at launch, at which point they'll be retailing for $70. Head on over to their KickStarter page to pitch in.
