How USB Power Delivery Looks Like for the Dell 30-Watt AC Adapter with 3 ft Power Cord - USB Type-C

The Dell 30-Watt AC Adapter with 3 ft Power Cord - USB Type-C ships with the Dell XPS 12 9250 to provide charging through the PC's Thunderbolt 3 ports using the common USB Power Delivery profiles of 15 watts (5 volts @ 3 amps), 24 watts (12 volts @ 2 amps), and 30 watts (20 volts @ 1.5 amps).

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 quickly confirm that the Dell 30-Watt AC Adapter with 3 ft Power Cord - USB Type-C does support the above mentioned PDO's for charging. Note some compliance failures were observed.
