What USB Power Delivery Charging Profiles are Supported on the Targus 45W USB Type-C Laptop AC Wall Charger

At a visit to a local Target in March 2017, the only third party USB Power Delivery they were selling were those from Targus.

The Targus 45W USB Type-C Laptop AC Wall Charger supports the following charging profiles over USB Power Delivery: 15 watts (5 volts @ 3 amps), 36 watts (12 volts @ 3amps), 37.5 watts (15 volts @ 2.5 amps), and 45 watts (20 volts @ 2.25 amps).

Here's a closer look at the Targus 45W USB Type-C Laptop AC Wall Charger's packaging and charger itself.

One annoying thing at Target is its use of security devices.  These security devices require you to find a store associate to buy something as simple as a charger so they can unlock the device.  Even after they unlock the device, a piece of the security mechanism is still on the packaging making it hard to open.

The Targus 45W USB Type-C Laptop AC Wall Charger provides charging using 15 watts (5 volts @ 3 amps), 36 watts (12 volts @ 3 amps), 37.5 watts (15 volts @ 2.5 amps), and 45 watts (20 volts @ 2.25 amps)  PDO's, which we verified through 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. Note some compliance failures were observed.
