Portable 4K workstation adapter

The StarTech DKT30CHCPD turns a USB-C laptop into a compact workstation with 4K HDMI video, Gigabit Ethernet, two USB 3.0 ports and 100W Power Delivery 3.0 charging. A built-in wrap-around USB-C cable keeps the unit tidy when moving between desks. It draws power from the host or an external USB-C supply.

Suits single-display USB-C workflows

This adapter fits users who need one 4K monitor, wired networking and legacy USB-A plus USB-C peripherals from a single port. The USB-A port supports fast charging for phones or tablets. It does not suit buyers who need more than one external display or whose host port lacks DisplayPort alt mode and USB Power Delivery 2.0 or 3.0 support.

One 4K HDMI output decides fit

The adapter drives a single monitor at 4K resolution through its HDMI female connector. If your workflow requires two or more external screens, this device cannot meet that need. Verify that your laptop’s USB-C port provides DP alt mode and PD 2.0 or 3.0 before purchasing.

Questions about this item

Will this adapter run a 4K HDMI monitor from a laptop that only has an older USB-C port without video alt mode?

The adapter requires the host USB-C port to support DP alt mode and USB Power Delivery 2.0 or 3.0; without those the HDMI output will not function.

How can I confirm the Gigabit Ethernet link is running at full speed after I plug it in?

Check the network adapter status in your OS — it should report a 1 Gbps link and the RJ-45 LEDs will show activity when traffic passes.

Does the box include a USB-C power brick for the 100W pass-through charging, or do I need to supply my own?

The package contains only the multiport adapter and an instruction manual; a USB-C PD power adapter must be purchased separately.
