Define "fast charging".

The best you can get via USB BC1.2 is 1.5A at 5V. This doesn't rely on anything special in the cable aside of requiring it to be able to carry USB 1.0/2.0 data, since it's signaled over D-/D+ pins.

You can get more than that, but then you're entering a proprietary mess territory where all bets are off.
