USB-C Dock with 100W PD

The StarTech DKT31CDHPD3 is a USB-C multiport docking station that adds video, data, network and charging through a single host connection. It targets professionals who need a compact desk hub for a USB-C, USB4 or Thunderbolt laptop or tablet.

Replaces separate video dongles and USB hubs

This dock consolidates an HDMI 2.0b or DisplayPort 1.4 output, a three-port USB 3.2 Gen 2 hub and Gigabit Ethernet into one device. The upgrade is worthwhile when you regularly connect a 4K 60Hz display, multiple 10Gbps peripherals and a wired network while keeping the laptop charged.

Plug-and-play with strain-relief cable

The 12.6in attached USB-C host cable includes a wrap-around manager to prevent tangles and reduce port strain on raised ports. Installation requires an available USB-C port with DP Alt Mode and a separate USB-C power supply for 100W pass-through charging; laptops without video-capable USB-C cannot use the display output.

Questions about this item

How much desk clearance does the 12.6in attached USB-C host cable need?

The 32cm cable reaches from a laptop on a riser stand or a raised Surface port to the dock without pulling on the connector, and the built-in wrap-around manager keeps the slack tidy for storage.

What host port must the laptop provide for video and 100W charging to work together?

A single USB-C, USB4 or Thunderbolt 3/4 port that supports DP Alt Mode and USB Power Delivery 3.0 is required; plug the laptop’s own charger into the dock’s dedicated PD port to pass 100W through.

When should the TPE-jacketed host cable be replaced?

Replace the cable if the jacket shows cuts, the connectors become loose, or video drops to below 4K 60Hz on a known-good display, as the cable is permanently attached and not user-serviceable.
