The USB-C Digital AV Multiport Adapter lets you connect your MacBook with USB-C port to an HDMI display, while also connecting a standard USB device and a USB-C charging cable. This adapter allows you to mirror your MacBook display to your HDMI-enabled TV or display in up to 1080p HD. It also outputs video content like movies and captured video. Simply connect the adapter to the USB-C port on your MacBook 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 MacBook.
