The 20W Charger is 9V / 2.2A, and the 15W Charging seems to be limited to this ( I am assuming the 5W deduction is due to induction inefficiency )

Having a higher profile such as 9V 3A should have worked, especially with PPS, but testing so far indicate MagSafe fails back to 7.5W.

Ah, right, not USB PD yet, not sure why I thought that.
