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 or iPad Pro display to your HDMI-enabled TV or display in up to 1080p at 60Hz or UHD (3840 by 2160) at 30Hz. It also outputs video content like movies and captured video. 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 iPhone, iPad, or iPod. You can also connect a charging cable to the USB-C port to charge your Mac or iPad Pro.
