Subscribe by EmailHow to Make a Cheap USB Solar Charger
November 6, 2007 by David |I am a huge fan of solar technology and I love to see it continue to progress, so imagine my surprise when I found a video on how to make a cheap, portable USB solar charger.
I really enjoyed this video, and would love to see more projects like this if anyone knows of any.

Grrr. Am I the only one who really hates it when people say “sodder” instead of solder?
(I’d also have thrown in a cheap 5v regulator just incase the cells were putting out more than 5v on a sunny day, some USB stuff is rather sensitive.)
can any1 teach me how to make one?
The only problem is that you have to have sorar panels that give the exact power that the battery requires to be charged according to its manual or else it will be destroyed after two-three times of being recharged that way.So it can be used only in case of emergency..
Despite that i have to say that it’s a brilliant idea.Keep on!
