Cheap Homeade Solar Powered Phone Charger

  1. Jul 18, 2013 #1
    I would like to build a small solar powered phone charger for when I go up to camp soon, I was planning on using a solar cell and I was wondering what I need to assemble a solar powered phone charger. Can someone help?

    I would google around for a 5W solar panel, nothing bigger than that really otherwise the panels might get to large to camp with. Since solar panels output DC you will need to place in a 5 Volt regulator between the panel and your phone (assuming your battery is rated at 5V). Then the output of that regulator should be enough to charge your phone.
