The purpose of this project is to make a solar charger for any phone or any device that supports USB charging The charger is fully dependable on solar energy as the only power source. The main objective is to create it using affordable materials and make to whole process easy enough to understand and reproduce for other people around the world.

Step 1: What You Need


Black (negative) and Red (positive) wires
4 “AA” Battery Holder (RadioShack) $3
4 AA Batteries
PARALLAX Solar Panel 6V@1W,125x63mm (eBay from China) - $13
Wire terminal 
PLA Filament for 3D Printer (optional)
Altoid Tin (optional)


Soldering Iron
Super Glue
3D Printer (optional)

There are two version that you can make depending on wether you own a 3D home printer such as Maker Bot. If you do, you can either download my design and print it or design you own. If you don't have 3D printer and want to go more low-budget, you can use Altoid Tin or anything else as the main structure for this charger. 
<p>Thanks for the great idea! I was just curious if you need a wire terminal with an On/Off switch to allow manual separation of the time spent charging the battery and the time spent charging the iPhone? Or does the wire terminal do this on its own by incorporating a higher resistivity to the wires that lead to the iPhone, to avoid a trickle charge effect directly from the solar cell?</p>
<p>I decided to build the circuit with only the solar panel, a USB port, and a transformer. It might help you Jaren.peplinksi </p>
<p>Hi Andrea, I have the same question as issa.kawar. What other types of wire terminals could I use? I am new to this, and I am currently shopping online for parts for this project. Please get back to me as soon as possible with some kind of direction for me, if you could! Thank you!</p>
<p>do we need the wire terminal? I don't have one and there is no way i can get it</p>
<p>excellent quite easy to follow and visualise . Just thinking of putting a stick on panel on the back of my I phone. Just to keep it topped up.</p>
<p>that's nice! thanks for sharing!</p>
