Meet the CrankCase: an iPhone 5/5s/6 case with a built-in hand crank to enable you to charge your phone anywhere. This is a lightweight, durable case with a quiet generator and a USB port to charge your smart devices. The crank arm can be used as a kickstand for your smartphone.
Don’t need a new case? You could always get a CrankBox, which happens to be an emergency charger compatible with iOS, Android, and Windows smartphones. These products are getting funded on Indiegogo at this time.
