Otherwise, this is a versatile power adapter for fast charging PPS available devices, but probably represents a poor value even at this sale price relative to third party adapters (such as Belkin or Insignia). Of course, if you have a very specific need for the wider PPS voltage ranges supported this could be one of the few options (though I personally struggle to recall any devices making use of PPS voltage ranges above 16V).
USB PD 3.1 PPS
PD: 5V/3A, 9V/3A,15V/3A, 20V/2.25A
PPS: up to 11V/3A, 16V/3A, 21V/2.25A max 45W
Good luck!

(2) Best in class for efficiency at idle and at low demand such as with magnetic stands watches and ear buds. (3) Voltage stability (4) Thermal stability, cool running at continuous full load.. (5) reliability and longevity. Users who require all of these characteristics do not have any lower cost options. It's a given that mainstream users will feel that they are better served by dual ports and smaller size even if these lack the above characteristics..
That's why Google engineered a better solution eliminating the need for special high amp cables. By increasing the voltage to 21 volts only a standard 3 amp cable is required. So this is a case of what the product has rather than what it does not have by design.
Apple doesn't sell charges built to Samsung's odd requirements. Calling out Google for doing the same is silly. Samsung users can still charge at SFC 1.0.
If reliability, durability, build quality, stable output and low operating temperature.are factors for me then I will gladly pay $9 more for a 10 year life. That's how long my Google home speaker adapters have been going 24/7 on a grid with daily surges.
For the benefit of other Pixel 9 Pro XL users any PPS charger which does 21 volts @ 2 amps is all that is required to enjoy the maximum 37 watt rate. That's 12 watts faster than Samsung using a standard 3 amp cable. The Otterbox 60 watt Premium Pro with 21V PPS is charging my P9PXL at the full 37 watt rate. Helluva great deal at $10 but only if it lasts three years and doesn't quit when I need it most.
QC is native to Snapdragon SOS used in Galaxy for years. Beginning with S8 or S9 Samsung added compatibility with power delivery but I made sure to use QC4+ and later PPS which has greatly extended battery life for me by keeping the battery temperature down. Feedback allows the device to continually call for precise voltage and amperage adjustments critical for optimal charging of Li-ion instead of leaping from 5 to 9 to 15 volts. Original PD should only be used when a PPS isn't available.
I suspect that 21V PPS is easier on the battery than 15V 3A power delivery however it is possible that flagship phones now have better internal control. The thing is that stepping down volts internally creates heat.
