I quite fancy having the ability to charge my phone while out on my push bike. I've seen a nice little Hub mounted dynamo that outputs 6v @ 3W The phone requires 5v. It would charge on minimum 500mAh, so in theory all that's required is to step down the voltage.
However, I think I would like to make it a bit more complicated than that
To get the most out of the dynamo, for times when I don't have the phone connected, I think I want to charge a bundle of batteries. The batteries could then be used for a camera ect. When the phone is connected, I would like it to be charged from the batteries @ 1A to give a quicker charge if possible. It is kind of like the **broken link removed** Kit but powered by dynamo rather than Solar. Actually I could just get a basic Freeloader kit, and use the dynamo as a secondary usb charger.. No that would be silly!
Do you think this is a feasible project to consider building the advanced idea, or just stick with the basic 500mAh one?
