9-in-1 USB-C Dock with Dual 4K@120Hz

The BFKK 9-in-1 USB-C Docking Station adds two HDMI outputs, gigabit ethernet, three USB-A ports and SD/TF card readers through a single USB-C connection. It delivers up to 85W power delivery to the host laptop while driving two external displays at 4K resolution and 120Hz refresh rate. The compact hub suits mobile professionals who need a full desktop I/O setup from one portable device.

Upgrade from single-port dongles

Basic USB-C adapters typically offer only one video output and lack wired networking or high-speed card slots. This dock replaces that clutter by combining dual 4K@120Hz video, 1000Mbps LAN and 5Gbps USB 3.0 ports in one unit. The jump is worth it when you regularly connect two monitors, need reliable ethernet and want fast photo ingest from SD cards without carrying multiple dongles.

Build integration and power budget

The dock draws 15W for its own operation, so a 100W charger yields 85W to the laptop — plan your power supply accordingly. It requires a host USB-C port that supports video alt mode and power delivery to enable all functions. The two USB 3.0 ports and one USB 2.0 port free up laptop sockets for peripherals, while the SD/TF slots let photographers and editors offload footage directly.

Questions about this item

What physical connection does the dock need on my laptop?

It connects through a single USB-C port on the laptop. The dock itself draws 15W, so with a 100W charger the laptop receives up to 85W.

Which driver step is often missed when setting up the dual 4K displays?

After plugging both HDMI cables, open the display settings and choose extend or mirror mode; the dock does not install a separate driver, the OS handles it.

What future replacement might the SD card slot need?

The slot reads SD and TF cards at up to 104MB/s. If the spring mechanism wears out, the whole dock would need replacing as the reader is not user-serviceable.
