I have a solar panel and I wanted to know how many volts the iphone uses so I can try to charge it with solar power. Here are the specs for the panel: 3 volts -- 200 mA 6 volts -- 100 mA 9 volts -- 50 mA 12 volts -- 50 mA Which one of the above should I put it on if i want to charge the iphone wit it? any help?
Generally, the output should be: DC 5.5V 400mA. you'd better choose "3 volts -- 200 mA". I used this black iPhone 3G power station not the solar charger. I think it is much easier and more convenient that yours.
