About the Apple USB-C Digital AV Multiport Adapter

The USB-C Digital AV Multiport Adapter connects a Mac that has a Thunderbolt 3 (USB-C) or USB-C port to a display that uses an HDMI cable. It also connects your Mac to USB-A devices and includes a USB-C port for charging your Mac notebook. All three ports can be used simultaneously.

These Mac models have one or more ports compatible with this adapter:

• iMac Pro
• iMac models from 2017 
• MacBook Pro models from 2016 or later 
• MacBook models from 2015 or later

  Learn about using 4K displays, 5K displays, and Ultra HD TVs with your Mac.

USB-A 

Use the USB-A port of this adapter with flash drives, cameras, and other devices that connect to USB-A for data transfer or charging. It supports data-transfer speeds up to 5Gbps (USB 3.1 Gen 1).

For example, you can connect the Apple Lightning to USB Cable to this port to sync and charge your iPhone, iPad, or iPod.

USB-C 

 

Use the USB-C port of this adapter for charging your Mac, 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.

This port delivers a maximum of 60W power, suitable for MacBook models and 13-inch MacBook Pro models. For the best charging performance on 15-inch MacBook Pro models, connect the power supply directly to your Mac, not through the adapter.

This adapter draws power from your Mac even when your Mac is asleep. To avoid draining the battery of your Mac notebook, unplug the adapter when your Mac is not connected to AC power.
