wind-powered hand-held charger

But do you know wind-powered hand-held charger? :-) It's not so popular. And I think someone know this cool gadget firstly. HYmini offers such cool gadget. It's palm-sized, comes in three colors (comes in black, white, and green), and can charge your gadgets with just a stiff breeze. It sounds cool, don't you think so?
                 All this wind-powered charger takes is a breeze of between 9 and 30 mph to keep the battery charging. Meanwhile, the translucent wind turbine glows green while in use, and the cool gadget contains an LED night light.
