Why Choose UGREEN CM639 Multifunction Adapter

Comprehensive Connectivity in One Hub

The CM639 combines essential ports in one convenient accessory. Its USB-A and USB-C data ports support compatible peripherals, storage devices, and accessories. HDMI and VGA offer display connections for different generations of equipment. This integrated design reduces the need to carry several separate adapters.

High-Resolution Display Support

The HDMI port supports high-resolution video output on compatible systems. Depending on the variant and host device, supported configurations can reach 4K at 60Hz. VGA provides an additional option for compatible older monitors and projectors. Display performance depends on the computer’s graphics capabilities and the display’s supported modes.

Fast USB Data Transfers

The USB-A 3.2 and USB-C 3.2 ports support data speeds up to 10Gbps under suitable conditions. The USB-A 3.0 port supports speeds up to 5Gbps. These connections help transfer files, connect external storage, and use compatible peripherals. Actual speeds vary according to the devices, cables, and shared bandwidth.

Stable Gigabit Ethernet Connectivity

The RJ45 port supports wired network speeds up to 1000Mbps. Ethernet can provide a consistent connection for video meetings, large downloads, and online collaboration.

The 3.5mm AUX port connects compatible headphones or speakers. Separate SD and TF slots make accessing memory cards more convenient for photographers and content creators.
