Charging your Mac or iPad Pro

USB-C 

Use the USB-C port of this adapter for charging your Mac notebook or iPad Pro, not for data transfer or video. For example, you can connect one end of the Apple Thunderbolt 3 (USB-C) Cable or Apple USB-C Charge Cable to the USB-C port of this adapter, and connect the other end to an Apple USB-C Power Adapter.

Because this adapter draws power from your Mac or iPad Pro even when your Mac or iPad Pro is asleep, you might want to unplug it when it's not also connected to power for charging.
