The JuiceTank is the first iPhone case to feature an integrated wall charger that folds flat to provide maximum portability. The automated plug deploys easily and allows you to plug your phone directly into any outlet. No cords required.
This is a trend: mobile devices will have everything they need to operate independently. Their own plugs, but also being able to download music without a PC, to upload pictures without a PC, and so on. And soon, wireless electricity. Untethered mobility.
