DIY – USB Solar Gadget Charger (Portable! – Great for OCCUPY!)

DIY – USB Solar Gadget Charger (Portable! – Great for OCCUPY!)

Share your ideas and participate in brainstorming with me for upcoming episodes of “Brian’s Insights”! – (NEW!)


SOLAR is the new GREEN thing these days, and California is a great place to utilize this technology!

I made a cool portable USB solar charger, using two 6v polycrystalline solar panels (the most efficient type), with a 12v car USB charger adapter (both available on eBay – Links below). The solar panels were about $12 each, and the USB car adapter was only about $3. I also bought a 12-foot cigarette lighter extension cord for $3 at Big Lots, that I cut in half, then used half so I can plug in my solar panel to my car, and have the other half to use with this setup, if necessary.

P.S. The case that I used to fit everything in, is an old Computer Tech toolkit pouch (originally held a bunch of screwdrivers and things). You can use one if you want, or you can put them in an old lunchbox, Tupperware container, a hollowed-out book, folding picture frames (with some modifications), a *small* briefcase …or try putting them on your backpack, or on a hat! Get creative, the main components are the solar panels and the USB adapter.


P.S.II Due to the current economy, donations of ANY amount, are always welcome! Contributions will go towards things like a BETTER CAMERA, microphone, editing computer, and even gas, car parts, groceries, etc – Yeah, it’s THAT bad!

hi sir, on the positive wire of your solar panels going towards the car charger, would it be possible to put a diode on the positve wire so that if the the solar panel is not charging due to NO SUNLIGHT, the diode will prevent batteries on your phone to be wasted or consume back to your solar this process right?

Sounds like you're feeding the voltage directly into the USB port, rather than through voltage regulation. I've got the panels wired up to output closer to 12v, then going into a car USB charger, which outputs around 5v. I'm using a bigger 10 watt panel now though – It's as powerful as plugging into the wall.

For 8 dollars at Radio Shack I can get 2 solar panels that will give off 5V .4A
At that rate an iphone 5 will charge fully in 4 to 6 hours. For 25$ I can get it so that it will charge faster than my computer, at around 5 volts, 1.25 amps. Everything but the solar panels you can find around home for free.
