In case you're wondering if you can use the USB Power Delivery based Dell 30-Watt AC Adapter with 3 ft Power Cord - USB Type-C (that came with the Dell XPS 12 9250) to charge your Nintendo Switch Console, we'll see how they perform here.

The Dell 30-Watt AC Adapter is plugged in to the Nintendo Switch Console that has been turned on with gameplay actively running while simultaneously using both the left and right Joy-Con controllers being attached to the Console. 

The Dell charger starts communicating with the Switch Console over USB Power Delivery by showing that it supports 15 watts (5 volts @ 3 amps), 24 watts (12 volts @ 2 amps), and 30 watts (20 volts @ 1.5 amps) power profiles.

With 1% battery charge remaining, the Nintendo Switch Console proceeds to request 6 watts (12 volts @ 0.5 amps) from the Dell 30-Watt AC Adapter.

The Switch Console later goes on to establish the full 24 watts (12 volts @ 2 amps) PDO power contract with the Dell charger allowing it to charge faster.

When the Dell 30-Watt AC Adapter is first plugged in to the Nintendo Switch Console while already being turned on with Joy-Con controllers attached to either side, the Switch Console at 1% battery starts off pulling current resulting in an 8.4 to 12 watts power band. When the game cartridge is played, the power pulled increases to the 15 to 20 watts band as the Console consumes more power used to support both the Joy-Con controllers and active gameplay. 

The Dell 30-Watt AC Adapter can be used to charge the Nintendo Switch Console over USB Power Delivery which performs similarly to the Nintendo Switch AC Adapter as seen in this review.
