Make a Fast Charge USB cable



In this video I show how to modify an existing USB cable to turn it into a fast charge cable, this is especially useful for Android devices using AC or Car charge adapters that are charging in USB mode instead of AC mode.

If the data pins (two middle pins) are shorted together, the Android device will assume it’s connected to an AC adapter and try to pull more power than the usual 450-500ma it pulls when it thinks it’s connected to a regular usb port.

Some people choose to cut their cable in half and then solder the wires, but this is a fiddly process and damages the cable shielding and general strength.
