Hello everyone. I have a DIY question for anyone who can help. I got the idea from a youtube video...http://www.youtube.com/watch?v=TrSUwZciExE
I'm constructing a USB solar charger using some old solar cells from garden lamps.
Each cell has an output of 2.3 volts.
I connected 4 cells together and I end up with a total output of 4.6 volts.
I connected a female USB port to it, then an iPod. It charged for about 30 seconds then stopped in full sunlight.
I thought maybe there wasn't enough voltage so I connected 2 more cells and I still end up with 4.6 volts and it wont charge.
I checked my connections and looked everything over and I didn't find anything disconnected.
Here's a picture. Anyone with advice?
