10Gbps USB-C Dock with 4K 30Hz HDMI

The STARTECH DKT31CHPDL is a compact 5-in-1 docking station that adds HDMI video, two USB-A ports, a USB-C data or power port and Gigabit Ethernet over a single USB-C 10Gbps host link. It targets mobile professionals using Ultrabooks, tablets or Thunderbolt 3 laptops who need extra connectivity without a bulky desktop dock. The 25cm attached cable reduces strain on the host port when the device sits on a riser or in a cramped workspace. Bus-powered operation means no separate adapter is required for data and video functions.

Upgrade from single-port dongles

This dock replaces basic USB-C to HDMI or USB-A adapters that offer only one extra port and no wired networking. The jump is worth it when you need simultaneous 4K 30Hz display output, two 10Gbps USB-A peripherals and a stable Ethernet link while keeping the host port free for 100W PD 3.0 pass-through charging. If your workflow only needs a single extra USB port or does not require wired networking, a simpler adapter remains sufficient.

Fits thin-and-light setups with 100W PD pass-through

The dock draws up to 15W for its own operation and passes up to 85W to the host, so a compatible 100W USB-C charger can power both the laptop and the hub through one cable. It works with Windows, macOS, Chrome OS, iPadOS and Android devices that support USB-C video and data. The USB-C port on the dock handles data or power delivery but not video, so a second display requires a separate adapter on another host port.

Questions about this item

How much desk space does the 14.40" long dock need?

The unit measures 14.40 inches long, 1.80 inches wide and 0.60 inches high, so it fits in a narrow strip alongside a laptop or monitor stand.

What is the correct order to connect the 100W PD pass-through so the host receives up to 85W?

Plug the laptop's USB-C charger into the dock's USB-C PD port first, then connect the dock's attached 10" cable to the host; reversing the order can limit power delivery.

When should the 10" attached cable be replaced if the strain relief cracks?

The cable is permanently fixed to the dock; if the strain relief or connector fails the whole unit must be replaced.
