[vc_row][vc_column][vc_column_text bordered=””]A lot of iPhone cases promise to extend your phone’s battery by 50%, 100%, 200%…
But that’s pretty lame. How about indefinitely?
Crankcase extends your phone’s life using an onboard ‘power generator‘. Basically, it lets you wind up your phone to get extra juice when you’re running low. And because this is built right into the phone, it means you’ll literally never be unable to get more life out of your phone.
So instead of searching around in pubs to find one with a power socket because you’re stranded and you need to make an urgent call… you can just crank it!
