The USB 3.1 spec isn't restricted to 5V. The charger can deliver up to 100W and the voltage can be negotiated between the charger and device.

- jhugg 10y agoRight, that's the USB Power Delivery (PD) spec and to get more than 5V, both sides (charger & device) need to support it. I'm guessing (no real idea) that the switch is vanilla 5V like most phones and tablets. Wouldn't mind being wrong.
