If you run out of batteries when listening to your MP3 player, you might get frustrated if there is no way of charging it right away. However, if you have a hand crank MP3 player like the one pictured here, you are good to go at any time of the day. 1 minute of cranking will provide you with 10 minutes of play time. Increase that to 60 minutes of cranking then you will get 10 hours as well as a butch arm.
If you get fed up of winding the crank then there are 2 other ways to power the MP3 player. You can power it via a USB port or with the AC adapter.
The Hank Crank MP3 player is fairly standard with 1Gb of internal memory and supports MP3 and WMA files. A flash light is also built in.

This is a great idea
Yes, a great idea, but how to get the product, how to make an order for delivering many product to resell as a commercial company?
let’s develop the idea. Why not a hand crank for all gadgets? turning around the handle you can generate a desired power supply by switching a linear multiswitcher having as output 5V, 4.7V, 5V, 6V, 7.5V and so on. Another thing, it is better a squeeze crank than a rotary crank think about this!
Great idea!
