How the USB Power Delivery Profile Looks Like for the Google Pixel 2 XL's 18W USB-C Power Adapter
The 18W USB-C Power Adapter ships with the Google Pixel 2 XL and supports the common USB Power Delivery profiles of 15 watts (5 volts @ 3 amps) and 18 watts (9 volts @ 2 amps). Note this 18W charger is different from the original charger shipped with the original Google Pixel (seen in this review) although still supports the same power profiles.
Using the USB Power Delivery Compliance C2 Tester from Granite River Labs to run just a subset of the full USB Power Delivery compliance test suite, we can verify that the Google 18W USB-C Power Adapter makes use of 15 watts (5 volts @ 3 amps) and 18 watts (9 volts @ 2 amps) PDO's for charging. Note some compliance failures were observed.
