S20 ultra will not 45watt charge

I've tried 2 different chargers capable of 45w but my phone both recognizes them only to fast charge. There's no way 2 charges are malfunctioning. I'm thinking my phone is defective. It does super fast charge with the 25w charger that came with the phone. Not a big deal, just would like my phone to do what it's capable of.

Are they 45 w pd chargers or are they like the Qualcomm fast charge type?

Hmm. I just bought a 12v car charger rated at 45w and it does work. Phone registers super fast charging 2.0,

Must of been a coincidence both wall chargers were defective.

Galaxy phone only super fast charge with Samsung 45 watt wall charge only. The other cannot reach to that 45 watt even though they rated 45 watt. Cause Samsung super fast 45 watt using different voltage 10V and 4.5A and the others used 9V and 5A I believe.

@Samsung_WcwF2vK I know that this post is a couple weeks old, but did you make sure the super fast option is turned on in your phone? Mine was defaulted off when I got mine.  Just thought I would mention it in case you missed it. I stumbled across the option on accident.
