Is there a third-party charger that can deliver that wattage?
Edit:
It is a power supply that came with an XPS 15
The text on the brick claims 5V 1A and 20 V 6.5 A, missing 9V and 15V levels and the current on 20V seems not to be standard. It does charge everything I have plugged it into, but they might all be falling back to 5V1A. The back text could also just not be telling the truth.

RavPower sells some dual-port models that will do 90W PD if you use one port or 45/45W or 60/30W using both ports. I ran my i9 MBP on the single port and it regularly drew 90W.
It's cheaper than the 96w charger that came with my Macbook.
