Spin Or Crank To Charge Your Phone

Wouldn’t it be nice if we could just charge our phones without having to rely on the wall socket? The “Mechanical Mobile” concept is quite simple. In one of the 2 designs, you can just spin the phone around your finger to generate the energy to charge your phone; the other design is for you to crank the phone. That being said, the cranking design does make one wonder if you could accidentally snap the phone in two while cranking.
