Solar powered iPod charger
So I've recently been trying to make my own homemade solar powered iPod charger out of two solar panels taken from solar lawn lights. I've since managed to solder a usb port to the panels and when the iPod is connected it says shows the "charged" sign, though the iPod is not infact charging, and is actually loosing power at the same speed it usually would. I don't have a volt tester which I think might reveal I'm not getting enough power to the usb port. Are there any suggestions?
