UGREEN CM639 10-in-1 USB-C Hub

A UGREEN CM639 hub makes it easier to build a connected workspace around your laptop. Instead of repeatedly disconnecting accessories, you can bring displays, storage devices, a wired network and memory cards together through your computer's USB-C connection. The combination of data expansion and power pass-through is especially useful for a desk where gaming accessories, productivity devices and external displays are used throughout the day.

Expand Your Screen Setup Connect external displays to create a more practical workspace for multitasking, editing and entertainment.
Connect Your Accessories Keep external storage, input devices and everyday peripherals connected through a central hub.
Reliable Wired Networking Add an Ethernet connection to a compatible laptop for a stable network link during gaming, meetings or large transfers.
Access Your Media Move photos, recordings and other files from compatible memory cards without relying on a separate card reader.

How the UGREEN CM639 Hub Expands Your Setup

Expansion connections bring display outputs, data peripherals, networking, card access and power input together in one hub.

Connectivity and Power

100W Maximum USB-C Power Delivery Input
1,000 Mbps Gigabit Ethernet Link Speed

Display Compatibility Depends on Your Computer

Windows

On supported Windows laptops, the hub can be used with external monitors for extended desktop arrangements. The available display configuration depends on the computer's graphics capabilities, USB-C video output and connected displays.

macOS

Compatible Mac computers can use the hub for external display connections. UGREEN's documentation for the reviewed variants explains that displays connected through the hub may mirror the same external desktop rather than provide independent extended desktops.

USB-C Video Support

A USB-C connector alone does not guarantee video output. For HDMI functionality, the computer's USB-C connection must support the required video transmission capability, such as DisplayPort Alt Mode.

Build Your Desk Connection in Simple Steps

Connecting the Hub

Connect to Your Computer Connect the hub's host USB-C connector to a compatible USB-C port on your laptop.
