First, you need to buy 4 resistors with this values: 2 of 50 kΩ, 1 of 100 kΩ and 1 of 150 kΩ.
Ok, you got 4 resistors, now you need a 5V power supply, you guessed it, another USB cable. An USB cable has +5V on pin 1 and -5V (or ground) on pin 4.

If you can handle a cutter, gently cut off the isolation and reveal the wires inside. See what colors the wires have that are connected at pin 1 and 4. Note or remember and then with an soldering gun solder the cables to the iPhone charger circuit like in the schematic. continue reading…
