## Long description

The StarTech.com USB-C to Ethernet Adapter US1GC303APD combines a Gigabit Ethernet port, a 3-port USB 3.0 Type-A hub and Power Delivery in a compact, portable adapter.

The adapter is self-powered from the host and is compatible with Windows, macOS, Linux and Chrome OS.

Its travel-sized design includes a built-in USB‑C cable for easy portability and eliminates the need to carry separate Ethernet and USB hubs. Power Delivery 2.0 pass-through enables charging of the connected laptop while powering the hub and adapter.
