Universal laptop dock

The Wavlink WL-UG49DK4 docking station adds dual external displays, wired networking and six USB ports through a single USB 3.0 or USB-C host connection. It targets office workers and mobile professionals who need a permanent desk setup for productivity applications.

Bundled adapters and power

The package includes a USB 3.0 A-to-B cable, a USB-A to USB-C adapter, a DVI-to-VGA adapter and a DVI-to-HDMI adapter so the DVI output can drive either legacy or modern monitors. A 36 W (12 V / 3 A) DC power adapter supplies the dock and downstream USB ports but does not charge the host computer.

USB 3.0 bandwidth limits

Dual video runs over the 5 Gbps USB 3.0 link, so the HDMI port reaches 3840×2160 at 30 Hz while the DVI port stops at 1920×1080 at 60 Hz. The two USB 3.0 ports share that same 5 Gbps pool with the video traffic, and the four USB 2.0 ports are limited to 480 Mbps. The dock is not recommended for gaming or video editing.

Questions about this item

Will the included 36 W power adapter ever need replacing, and can I source a standard 12 V 3 A unit?

The dock ships with a 12 V 3 A DC adapter rated at 36 W; any equivalent 12 V 3 A supply with the same barrel plug will work as a replacement.

Which video output hits its resolution ceiling first when I run both monitors all day?

The DVI port caps at 1920×1080@60 Hz, while the HDMI port reaches 3840×2160@30 Hz, so the DVI path is the first limit.

Does the dock get noisy or hot when the Gigabit Ethernet and all six USB ports are active continuously?

The unit has no fan and relies on passive cooling; under full port load it warms slightly but stays silent.
