How the BatPower PD6's AC Adapter Uses USB Power Delivery to Charge the Nintendo Switch Dock

Let's see how the Nintendo Switch Dock supports USB Power Delivery charging with an alternative charger like the BatPower PD6's AC Adapter aside from its own 39 watts based Nintendo Switch AC Adapter (that comes with the Switch). Note the BatPower PD6's AC Adapter is supplied with the BatPower PD6 Power Bank which also enables charging using USB Power Delivery over USB Type-C.

Before connecting to the BatPower PD6's AC Adapter, we first slot in the Nintendo Switch Console into the Switch Dock while also attached with both left and right Joy Con Controllers. At the same time we also link up a HDMI TV from the Switch Dock.

We then connect the Dock to the BatPower PD6's AC Adapter through the BatPower round to rectangle connector adapter and BatPower USB Type-C Adapter. The BatPower adapter begins negotiation with the Dock over USB Power Delivery by advertising its source capabilities of 15 watts (5 volts @ 3 amps), 27 watts (9 volts @ 3 amps), 36 watts (12 volts @ 3 amps), 45 watts (15 volts @ 3 amps) and 60 watts (20 volts @ 3 amps). To see that the BatPower adapter only supports max 60W instead of 90W as promised is disappointing.

We can see that the Nintendo Switch Dock initially requests only 7.5 watts (15 volts @ 0.5 amps) from the BatPower PD6's AC Adapter.

After the BatPower PD6's AC Adapter delivers the 7.5W, the Switch Dock follows up to request the max 3 amps current @ 15 volts which the adapter complies.

When we initially connected the BatPower adapter to the Switch Dock (containing the Switch Console with Joy-Con Controllers), the Switch Dock starts off briefly pulling 21 watts (15 volts @ 1.4 amps) before rapidly changing current resulting in a 7.5 to 15.5 watts power band. When HDMI is connected to the TV, the power pulled goes up to the 9 to 17 watts band. The Dock actually consumes more power used to support the HDMI port and Console with Joy-Con Controllers, and is a lot higher during active gameplay. This power is quite similar when compared to using the Dock in another review without using any of its USB ports.

We can confirm that the BatPower PD6's AC Adapter can be used as a replacement power supply for the Nintendo Switch Dock over USB Power Delivery.
