Sometimes you feel like you can't leave the house without needing to charge your phone. Here's an easy solution for you—iBattz's new iPhone 5 case comes complete with an extra battery you just clip onto the back. Voila!

You might like this even if you're a case nudist. The thin $80 2500 mAh Mojo Hi5 Powerbank Case comes in white or black, so you still see the phone first, not a bulky sleeve. It's supposed to double your phone's daily lifespan, and goes on sale tomorrow. You can order it from iBattz or Amazon. And you won't be that asshole at the bar asking if he can plug his phone in for a sec. [iBattz, Amazon]
