USB-C Gigabit adapter for laptops

The STARTECH US1GC30DB adds a wired 10/100/1000Mbps Ethernet port to any computer with a USB Type-C connector. It draws power from the USB 3.0 bus and requires no external supply. Driver support is native on recent Windows, macOS, Linux and Chrome OS releases.

Suits thin laptops without onboard Ethernet

Travellers and remote workers who need a reliable wired link on ultra-portables will find the cableless design convenient. Buyers whose devices only offer USB 2.0 Type-C ports will not achieve Gigabit speeds. Desktop users with free PCIe slots should consider an internal card instead.

USB 3.0 bus delivers full Gigabit bandwidth

The adapter operates over a USB 3.0 (5 Gbps) connection, providing headroom for 1000Mbps throughput. A USB 2.0 link would restrict the connection to lower rates. The single RJ-45 port and activity LEDs complete the feature set.

Questions about this item

What comes in the box and is a cable required?

The package contains only the adapter itself. No separate cable is needed because the USB-C connector plugs directly into the host port.

Which speed version should I choose for a 1000Mbps network?

This single model handles 10, 100 and 1000Mbps automatically, so there is no separate version to select.

Will I actually see 1000Mbps throughput over the USB 3.0 link?

Yes, the USB 3.0 bus provides 5 Gbps bandwidth, which is enough to deliver full Gigabit Ethernet performance in practice.
