UGREEN USB-C to RJ45 2.5G Ethernet Adapter (Space Gray) | 70446
The UGREEN CM275 (item 70446) is a USB-C to RJ45 Ethernet adapter in space gray that supports 2.5 Gbps wired networking. It plugs into the USB-C port of a laptop or tablet and adds an RJ45 port that also works at 10, 100 and 1000 Mbps on ordinary networks.


2.5G Ethernet: The adapter supports network speeds up to 2500 Mbps, faster than a standard Gigabit port. This is useful when your switch, router or NAS has 2.5G ports, for example when copying large files to network storage.
Backward compatible: It also runs at 10/100/1000 Mbps, so it works with the Gigabit and 100 Mbps routers and switches found in most homes and offices today, and is ready for a later upgrade to 2.5G equipment.
USB-C connection: It connects directly to a USB-C port, which makes it a practical way to get wired internet on thin laptops that no longer have a built-in Ethernet port.
Works with
Laptops and computers with a USB-C port running Windows or macOS.
Good to know
2.5 Gbps is reached only when the device at the other end (switch, router or NAS) also has a 2.5G port; with a Gigabit port the link runs at up to 1 Gbps. The real speed is also limited by your internet plan.
