Crank chargers for your mobile phone

Here is a collection of crank chargers that I found online. They are called crank chargers because there is a crank which you rotate to generate power. They are made by various Chinese manufacturers and are around 10$US. It doesn't generate alot of power...a few minutes cranking can provide a few minutes for your phone. As you can see, there are many variations on the design. Some have built in flashlights, radio (with loudspeaker), alarm clock, compass, and pocket knife. This is good to have around together with those solar panel chargers.
