Here is a small and useful tutorial on how to use batteries to charge your phone. In my case I used 3xAA batteries but it also works with only two in series.
This is a expansion of a previous project. Be sure to watch this one first:
Step 1: Watch the Video!
The video shows you how simple it is to use a premade circuit to charge your phone. I think anyone can hook up two wires to a circuit. It is perfect for beginners
Step 2: Order Your Parts!
Here is the small list of parts you will need to make this build happen:
DC DC Converter: http://www.ebay.com/itm/DC-DC-Converter-Step-Up-Bo...
2xAA Battery Case: http://www.ebay.com/itm/AA-Battery-Case-2XAA-2xAA-...
3xAA Battery Case: http://www.ebay.com/itm/AA-Battery-Case-Battery-Ho...
Step 3: Success!
That was a piece of cake! Now it is time to do more difficult projects.
