Solar Powered Usb Charger
Here is the solar powered USB charger I made from the directions on Hiker’s Journal. I use it to charge my camera, phone and mp3 player while hiking. Learn how to make one here: http://www.hiker…

hey Rory,i’ve made one of these but my total output is between 6 and 6.5 volts…DAMNDo you think i could use some kind of a voltage regulator?, those things that are like 2 bucks?A? reply would be greatly appreaciated.Thanks
Have you got? a blocking diode in that circuit? Otherwise you could end up with a dead/low battery in the morning if you was to keep it pluged in overnight when the lights are out.
By using the USB port of the phone you would not need a diode. The phone thinks that is is simply unpluged &? it stops the charging cycle. You would only need a block if you were going directly to the phones battery & thus bypassing the phones regulated charging device.
YES! Thank you so much! Ive been wondering this myself and now it makes sense. That the device would have its own diode. Thanks? (even though its been 2 months)
sorry,? thnkx.
You have absolutely no idea what you are talking about…I? know you didn’t connect this..cause if you did I know you would have failed miserably!
Why would I have failed? I flip the thing over over in the video so you can see how simple it is. All it takes is sodering wires in the right places on the back of the panels and wiring it to the negative and positive wires in the female USB plug. And you’re done. For bigger panels you need a charge regulator on there, but these are small panels, so you’re fine as long as nothing is plugged? in when the panels are not in the light (in that case, the panels would drain the batteries).
That rocks boss….who needs those silly solar walkway lights anyway?:)Im building panels from scratch….check out? my vids.
someone want to chati cant watch this video Yx?
Adding batteries and a power regulator is the next step. The batteries will help charge? things better (especially in no light situations) but will take longer to charge with only one of these panels.
