How to create an usb power adapter for your nintendo ds out of an usb cable & your nintendo ds charger.
Step 1: Analyzing
I noticed that my ndsl charger supplies almost 6v, so i decided to use a normal usb port to charge my ds, also because my pc can supply 5.1 volts that are perfect for charging it (and also because it is always turned on during the day).
1) Take apart your nds charger.
2) Look inside it & search for the power cord.
3) Using your tester(V), check & write down the position of the tiny cables inside the cord.
4) Close your charger, plug it on an outlet & write down the + & the - on the connector.
