Connectivity hub for USB-C laptops

The DKT30CHVSCPD adds an HDMI port, a VGA port, three USB 3.0 Type-A ports, SD and microSD card slots, and a Gigabit Ethernet jack through a single USB-C connection. It is aimed at professionals who need legacy video outputs and wired networking on modern ultraportables. Power Delivery 3.0 passes up to 85W to the host laptop while the adapter is in use.

Sustained multi-port operation

The aluminium enclosure acts as a heatsink for the VL817 and PS8338B controllers during continuous 4K video output and simultaneous data transfer across three SuperSpeed ports. The Realtek RTL8153 Ethernet controller maintains link stability under load without throttling. The 4.6-inch tether keeps the adapter close to the chassis, reducing cable strain on the host port during extended sessions.

Plug-in deployment with port checks

No driver installation is required on macOS or Windows for video, data, Ethernet or card-reader functions. The adapter draws operating power from the host USB-C port, so the laptop port must support DP Alt Mode and PD 3.0; otherwise video and charging will not activate. The fixed 4.6-inch cable limits placement flexibility on desks with recessed ports.

Questions about this item

How warm does the 4.6 inch adapter get when the 85 W PD 3.0 pass-through and all three USB 3.0 ports are active all day?

The compact aluminium housing dissipates heat from the VL817 and RTL8153 controllers; under full 85 W pass-through and peripheral load it becomes warm but stays within normal operating limits.

Which laptop port must my machine provide so the HDMI, VGA, GbE and card readers all function through this single adapter?

Your host USB-C port must support both USB Power Delivery 3.0 and DisplayPort Alternate Mode; without DP Alt Mode the video outputs will not activate.

Will the HDMI and VGA outputs work simultaneously with a legacy 1080p monitor on the VGA side?

Yes — the ANX9833 controller drives 4K HDMI and analogue VGA at the same time, so an older 1080p display on the VGA port works alongside a 4K screen on HDMI.
