Apple USB-C Digital AV Multiport Adapter
The USB-C digital AV multiport adapter lets you connect your USB-C enabled Mac or iPad Pro to an HDMI display, while also connecting a standard USB device and a USB-C charging cable.
This adapter allows you to mirror your Mac Display to your HDMI-enabled TV or display.
Simply connect the adapter to a USB-C or Thunderbolt 3 (USB-C) port on your Mac or iPad Pro and then to your TV or projector via an HDMI cable (sold separately).
Use the standard USB port to connect devices such as your flash drive or camera or a USB cable for syncing and charging your iOS devices.
You can also connect a charging cable to the USB-C port to charge your Mac or iPad Pro.
