Portable Gigabit Ethernet Adapter

This USB-C to RJ45 adapter adds a wired Gigabit network port to laptops, Chromebooks and desktops that lack a built-in Ethernet socket. It connects through a USB 3.0 Type-C male plug and supports 10/100/1000Mbps speeds under IEEE 802.3, 802.3u and 802.3ab standards.

Plug-and-Play USB-C Integration

The adapter draws power directly from the USB bus so no external supply is needed. Native driver support in Windows 7 and later, macOS 10.14 and later, Linux kernels 4.11 LTS and Chrome OS means it works immediately without software installation. Thunderbolt 3 and Thunderbolt 4 ports accept the connector for flexible placement.

Sustained Wired Throughput

The Realtek RTL8153 chipset maintains full Gigabit rates during long file transfers and continuous streaming where wireless links can fluctuate. Aluminium housing dissipates heat during extended use, keeping performance stable without throttling. The compact form factor leaves adjacent ports free for other peripherals.
