The Ugreen CM639 is a versatile 10-in-1 USB-C hub that turns a single USB-C port into an expanded connection hub. It offers two HDMI ports with 4K@60Hz video support, two USB-A and two USB-C ports (both 3.2, up to 10 Gbps), SD and TF card readers, a gigabit RJ45 port and a USB-C PD port for up to 100-watt charging. With its help, you can connect several devices at the same time, perform lightning-fast data transfer and use two high-resolution monitors.
You can instantly access 10 additional ports - from USB-A and USB-C ports to HDMI and memory card readers. With the Ugreen CM639, you can conveniently connect accessories, external drives, monitors, projectors, printers and more.
The two HDMI ports allow you to display 4K resolution video at a 60Hz refresh rate. You can work on two screens at the same time, increasing efficiency and comfort. The hub supports MST mode under Windows and also supports dual 4K@60Hz video under macOS.
With up to 10 Gbps USB-C 3.2 and USB-A 3.2 ports, transferring large files is a snap. USB-A 3.0 ports, on the other hand, provide transfer speeds of up to 5 Gbps for fast copying of documents, photos or videos.
The USB-C PD port supports up to 100-watt charging, so you can charge your laptop, tablet or smartphone in seconds - even while using the hub's other functions at the same time.
The built-in RJ45 Gigabit Ethernet port (10/100/1000 Mbps) provides fast, stable and reliable network access - ideal for office work, streaming or online gaming.
The hub allows you to read SD and TF cards at the same time, so you can quickly download photos and recordings from cameras, drones or sports cameras.
