It is supposed to support it and it does charge reasonably fast on high watt charge pads but I don't believe I saw any indicator as to how fast.

I have this one. The Samsung Fast Charge model 2072. It tells me it will take 2 hours to charge from 30-40% to 100%. This seems pretty standard to me however I have it plugged into an Anker Charging hub but not in the high power port. I will try it after I get home from work and report back if I see a difference in reported time to charge.
