The UGREEN CM639 is a premium docking solution designed for users who need maximum connectivity and performance from a single USB-C port. It transforms your laptop into a fully equipped workstation by adding multiple USB ports, high-resolution display outputs, and charging capability in one device.

Unlike basic hubs, this adapter is built for heavy use. It supports multiple monitors, high-speed data transfer, and continuous power delivery, which makes it suitable for professionals, developers, designers, and business environments.

Because it is plug-and-play, you can connect it instantly without installing drivers. Therefore, it is easy to deploy in offices, retail setups, and IT environments.

Performance and Functionality

The UGREEN CM639 delivers excellent performance across all functions. It supports ultra-fast data transfer speeds of up to 10Gbps, allowing you to move large files such as videos, backups, and design files quickly.

In addition, the Power Delivery feature (up to 100W) ensures your laptop remains charged while using all ports. This makes it ideal for continuous work without interruptions.
