The JuiceTank is the first iPhone case to feature an integrated wall charger built into the case.

The automated plug deploys easily and allows you to plug your iPhone 4 or iPhone 4S directly into any outlet. No cords required.

Designed by Lloyd Gladstone and Jesse Pliner. The JuiceTank’s creators are currently trying to raise $125,000 through Kickstarter to put this clever design into production, and if you are one of the first 400 people to back them you can reserve one for just $40. If you decide to wait until they’re available for sale, expect to pay $70.
