The UGREEN CM639 10-in-1 USB-C Hub is designed for desk setups that need more than basic USB expansion. It combines dual displays, high-speed USB, wired networking, card readers and Power Delivery in one adapter, making it a strong fit for productivity users working from a USB-C laptop. Two HDMI outputs support up to 4K at 60Hz, with multi-display behaviour depending on the connected operating system and host hardware. Windows systems support MST configurations, while macOS follows its own external-display limitations. Gigabit Ethernet provides a stable wired connection for office networks, large downloads and online gaming. On the data side, the hub includes both 10Gbps and 5Gbps USB ports, giving fast external SSDs and other high-speed devices more bandwidth than entry-level hubs. Separate SD and TF card slots support simultaneous media access, useful for photography and video workflows. A USB-C Power Delivery input supports up to 100W charging from a compatible charger. The laptop must support charging through the connected USB-C port, and the final charging rate depends on the host and power source. For users who want one connection for monitors, network, storage and charging, the CM639 is well suited to a permanent or semi-permanent workstation where the extra ports will be used regularly rather than occasionally.
