Ampware Hand Crank iPhone Case
Ever thinner devices mean ever smaller batteries. You can extend your phone's life with a battery case, but at the end of the day, it's just another gadget to charge. The Ampware Hand Crank iPhone Case gives you an alternative. Using an on-board generator, five minutes of cranking can deliver a full hour of normal use or five hours of standby juice, guaranteeing you'll have power when you need it most while keeping your iPhone 6 or 6S safe from drops and bumps.
