Hand-Crank iPhone Case Ensures You Always Have Power

No matter how long you charge your iPhone before leaving for the day, it seems to always die right when you need it – but this fantastic case will make sure that you never have to hunt wildly for an outlet ever again. The Gridcase Reactor is just a prototype at this stage, but it has the potential to be the case that everyone has on their iPhone 5 in the future.

The Reactor looks a lot like a regular iPhone 5 case, but it hides a cool little secret. On its back is a pop-up crank that you can use to give your smartphone a little power boost when it’s needed. You can crank it briefly for a small power boost or keep going until the battery is fully charged. Since arm power doesn’t generate a ton of energy, you’ll probably be cranking for a very long time…but if you absolutely have to charge your phone, all of that work might be worth it.

Although the idea is a pretty cool one, there are some obvious drawbacks. The case will make your iPhone significantly larger and heavier, and cranking a hand crank in public is something that most iPhone users won’t be super-thrilled about. But if your iPhone is your life and you don’t want to go even a second without it, the Gridcase Reactor might be the perfect solution.
