How do I make a DC 5.5v 800mA solar charger charge my ipod touch 4th gen?

Output is via usb but when i plug it in it wont charge?
Its solar charger P-1100f and seems to work with every electronic I have except my ipod touch.


There's a couple of extra "magic" resistors needed for Ipods - deliberately done to make it difficult for you.

If you look at the "Mintyboost" and the design there, they explain what's needed.

Is it possible to just switch it out with a USB from my computer because wouldn't it have the resistors too?
I don't think so. Try it.
