Cell phone solar charger voltage Answered
I am a newbie so sorry for such a basic question. I want to build a solar cell charger with a USB plug. My problem is finding a USB port with the appropriate voltage. Would I be able to take a car lighter USB charger and alter it or use resistors so that it would work for me? I'm not really sure how to go about obtaining or building a USB port for my charger. I appreciate any help!
