There are no fast charging USB C to A cables?

USB-A port doesn't have extra pins required for USB-PD fast charging.

USB C->A by the standards maxes out at 5V and 2.4A.

Ah, thanks! Was confused by the OnePlus' "Dash chargers" which don't go by the standard and do more.

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.

Maybe not by USB standards, yet plenty of chargers have no problem using other protocols to negotiate e.g. 9V charging. My Pixel 6 Pro for example negotiates 9V charging from USB-A ports that support it.
