I tried charging a samsung s24 using both the normal ports and the qc3 port and in both cases the charge current was about 0.5a and the charging voltage was 5.0v. Admitedly it was a cheap cable. Anyway for now i am not sure whether the fast charging actually works. The other issue i had is that i dropped the charger on a carpeted floor and the big pin snapped off. I will have to glue it back on but it is ridiculously weak.
