Portable USB-C multiport adapter

The StarTech DKT31CMDPHPD adds seven ports through a single USB-C connection with a 12-inch attached cable. It delivers 4K 60 Hz video over HDMI 2.0 or Mini DisplayPort 1.4 Alt Mode and falls back to 4K 30 Hz with DisplayPort 1.2. The hub includes three USB-A ports and two USB-C ports running at 10 Gbps. One USB-C port handles up to 100 W Power Delivery pass-through with 15 W reserved for the adapter.

Upgrade from single-port dongles

This replaces basic adapters that only mirror a screen or add one USB socket. The jump is worth it when you need simultaneous 4K output, gigabit Ethernet, multiple 10 Gbps peripherals and laptop charging from one compact device. It also supersedes older 5 Gbps hubs that cannot saturate modern external SSDs. Buyers who only need a second monitor or a few low-speed ports will not use the bandwidth or power headroom.

Fits thin-and-light workflows

The 6.3 by 1.8 inch footprint and 0.19 lb weight slip into a laptop sleeve without bulk. It draws bus power when no charger is connected and works with Windows 8.1 through 11, macOS 10.13 onward, Chrome OS, Ubuntu 18.04 and 20.04, iPadOS and Android. The single host cable carries video, data and charging so no extra power brick is required for the dock itself. Builds that demand dual-display output or Thunderbolt-certified bandwidth need a larger station.

Questions about this item

How much desk space does the 6.30" x 1.80" x 16.70" dock occupy?

The unit measures 6.30 inches long, 1.80 inches wide and 16.70 inches deep, so it fits in a compact footprint beside a laptop.

Which USB-C port must I use to deliver up to 85W of pass-through charging to my laptop?

Connect the host USB-C cable to the single port labelled for Power Delivery; the other USB-C port is for data only.

When should I expect to replace the attached 12-inch host cable?

Replace the cable if the USB-C connector becomes loose, the sheath frays, or intermittent video or data errors appear.
