UGREEN CM648 USB-C 2.5GbE Ethernet Adapter in Aluminum

The UGREEN CM648 is a USB-C to Ethernet adapter that adds a 2.5GbE RJ45 port to laptops, tablets and supported phones that have no built-in LAN connector. Plug it into a USB-C data port and you get a stable wired connection for large file transfers, NAS access and network backups.

This UGREEN Ethernet adapter supports 10/100/1000/2500Mbps link speeds, so it works with standard Gigabit routers as well as newer 2.5GbE switches. It is bus-powered and needs no separate power adapter, which makes it easy to carry in a laptop bag or keep on your desk.

Key Features

• 2.5Gbps Ethernet link speed: Supports Multi-Gigabit connections over the RJ45 port, so large files and NAS transfers can move faster on a compatible 2.5GbE network.
• Realtek RTL8156BG controller: Handles USB-to-Ethernet communication and automatic speed negotiation, so it connects at the best rate your network equipment supports.
• USB 3.0 Type-C host interface: Offers up to 5Gbps of host bandwidth, enough for the adapter's maximum 2.5GbE link speed.
• Backward-compatible networking: Works with 10/100/1000Mbps connections, so you can use it with existing Gigabit routers and switches today and keep it when you upgrade.
• Aluminum housing with integrated USB-C cable: A compact silver body that suits laptop bags, office desks and portable workstations, with no loose cable to lose.
• Link and activity LED indicators: Show network connection and data activity at a glance, which helps when checking whether the cable and port are working.
• USB bus-powered: Draws power from the USB-C host connection, so there is no external power supply to carry.

Why Choose the UGREEN CM648 USB-C to Ethernet Adapter

Many modern laptops and tablets have dropped the Ethernet port. A wired connection is still the more reliable choice for video calls, large downloads, remote work and file transfers. The CM648 restores that connection through a single USB-C port.

The 2.5GbE capability gives you room to grow. On a Gigabit network it runs at the lower supported speed. If you later move to a 2.5GbE router, switch or NAS, the same UGREEN adapter can take advantage of it. It combines a durable aluminum body, a trusted Realtek controller and bus-powered convenience in one portable device.
