The USB-C Digital AV Multiport Adapter allows you to connect your USB-C-enabled Mac or iPad Pro to an HDMI display, even as also connecting an ordinary USB device and a USB-C charging cable.
This adapter permits you to mirror your Mac display in your HDMI-enabled TV or display.
Simply connect the adapter to a USB-C or Thunderbolt 3 (USB-C) port for your Mac or iPad Pro and then in your TV or projector by the use of an HDMI cable (sold one at a time).
Use the usual USB port to connect devices such as your flash drive or camera or a USB cable for syncing and charging your iOS devices.
You’ll be able to also connect a charging cable to the USB-C port to charge your Mac or iPad Pro.
