Ports and Features

Parts labeled diagram of the USB-C Slim Multi-Port with Ethernet Adapter with 7 labeled components.

1. USB-C Connector: The attached USB-C cable and connector that plugs into the USB-C port on your laptop or tablet. This is the only connection the adapter needs.
2. Ethernet Port: Wired network connection at Gigabit speeds, up to 1 Gbps.
3. LED Indicators for Ethernet Connection: The two small LEDs beside the Ethernet port. They show link and activity status for the wired network connection.

6. 2X USB-A Data Ports (5Gbps): Two USB-A 3.0 ports for data transfer, up to 5 Gbps, with a maximum output of 5V/1A per port. They do not support the Apple SuperDrive, and only one external hard drive should be connected at a time.
