USB-C multiport adapter

The StarTech DKT30CHD adds HDMI, Gigabit Ethernet, USB-A and USB-C ports to a laptop through a single USB-C connection. It suits mobile professionals who need a compact dock for external displays and wired networking. Thunderbolt 3 ports are also compatible. The adapter draws power from the host device.

Thermals noise and power

The unit has no fan and operates silently during typical office workloads. Power is supplied entirely by the host USB-C port so no external brick is required. Heat remains low because the adapter only bridges signals rather than driving heavy compute tasks. Extended 4K video output may warm the enclosure slightly.

Build fit and freedoms

One USB-C cable carries video, data and network traffic, freeing the other side of the laptop for chargers or peripherals. The HDMI port drives a single display at 4096 x 2160p 24 Hz or 3860 x 2160p 30 Hz. Gigabit Ethernet uses the RTL8153 controller with Auto MDIX. Buyers who need multiple simultaneous monitors or powered USB-C charging cannot use this adapter alone.

Questions about this item

How do I connect the DKT30CHD to my laptop and which step is often missed?

Plug the USB-C cable into a Thunderbolt 3 or USB-C port that supports video output; the step often missed is confirming the port carries DisplayPort Alt Mode before connecting.

What part of the adapter will need replacement first with daily use?

The USB-C cable and its 24-pin connector endure the most insertions; the GL3523 hub and RTL8153 LAN chips are solid-state and do not wear out.

What resolution limit appears first when I drive an external display continuously?

The PS176 HDMI chipset caps output at 4096 x 2160p @ 24Hz or 3860 x 2160p @ 30Hz; sustained use cannot exceed these rates.
