If you happen to lose the charger that went with the Apple MacBook (Early 2016) and have access to the Dell 30-Watt AC Adapter with 3 ft Power Cord - USB Type-C, you might wonder if you can use the same charger with the Apple MacBook (Early 2016).
Using Granite River Labs USB Type-C Test Controller and software, we could confirm that USB Power Delivery is working correctly with the Dell 30-Watt AC Adapter with 3 ft Power Cord - USB Type-C offering 5 volts @ 3 amps (15 watts), 12 volts @ 2 amps (24 watts), and 20 volts @ 1.5 amps (30 watts) to the Apple MacBook (Early 2016)?
The Apple MacBook (Early 2016) then requests 20 volts @ 1.5 amps (30 watts) of power and gets charged properly from the Dell 30-Watt AC Adapter with 3 ft Power Cord - USB Type-C. This is a similar power level that the Apple MacBook (Early 2016) gets from its own Apple 29W USB-C Power Adapter as shown in this review.
