Product information

Description

The StarTech USB-C to Gigabit Ethernet adapter US1GC30B provides a wired Ethernet port via a USB-C host interface. Designed to add a stable LAN connection to laptops, tablets and other USB-C or Thunderbolt 3 devices, the adapter supports up to 5000 Mbit/s (USB 3.2 Gen 1) host bandwidth and delivers 10/100/1000 Mbps network connectivity using an integrated Realtek chipset. The compact, black, USB-powered design offers a portable option for machines that lack a built-in Ethernet jack and enables large file transfers and reliable network access for work or home environments.

Advantages

This USB-C to Gigabit Ethernet adapter provides full Gigabit network speeds through a USB-C or Thunderbolt 3 port without installing an internal Ethernet card. Native driver support for major operating systems simplifies setup: plug the adapter into a compatible USB-C port and connect to a wired LAN. The adapter uses checksum offload and large-send offload to help improve network throughput and reduce host CPU overhead. Its small, lightweight, USB-powered form factor makes it easy to carry and use with portable devices.

Suitable for

Connecting laptops or tablets to wired office or campus networks
Streaming or transferring large files over a reliable Ethernet link
Using wired networks where Wi‑Fi is unavailable or unstable
Temporary wired connections for presentations, meetings or travel

Key specifications

Interface to host: USB Type-C (USB 3.2 Gen 1 / 5 Gbit/s)
Network speeds: 10/100/1000 Mbps (Gigabit Ethernet)
Maximum host transfer rate: up to 5000 Mbit/s
Chipset: Realtek RTL8153 (native driver support on major OS)
Power: USB-powered (no external power adapter required)
Color and finish: black, compact form factor

How to use

Connect the adapter’s USB-C plug to a compatible USB-C or Thunderbolt 3 port on your computer. Plug an Ethernet cable from your network into the adapter’s RJ45 port. Most systems with native driver support will detect the adapter automatically and configure network settings; if manual configuration is required, use the operating system’s network settings to select wired LAN and set IP configuration as needed. No external power supply is required because the adapter draws power from the host USB-C port.

Usage recommendations

For optimal performance, use a Cat5e or higher-rated Ethernet cable and ensure the host device’s USB-C port supports USB 3.2 Gen 1 (5 Gbit/s) or Thunderbolt 3. When transferring very large files or running bandwidth-intensive tasks, confirm that network infrastructure (switches, routers) supports Gigabit speeds to avoid bottlenecks.
