Pocket-Sized Connectivity Hub

The Plugable UD-CUBE is a compact docking station that adds an HDMI display output, gigabit Ethernet and three USB ports through a single USB-C connection. Weighing 130g, the cube-shaped unit fits in a palm and is intended for mobile professionals who need quick expansion at a desk or in a meeting room. It supports Windows, Mac and Chromebook hosts that provide DisplayPort Alternate Mode over their USB-C port.

Best for Single-Screen Mobile Work

This dock suits users who need one external monitor up to 4K at 30Hz alongside a wired network link and a mix of USB 2.0 and USB 3.0 peripherals. It does not charge the host laptop, so buyers who require power delivery through the dock should consider a different solution. Systems without Alt Mode video support cannot drive the HDMI output.

Host Port Must Support Alt Mode Video

The single specification that determines compatibility is whether the host USB-C port implements DisplayPort Alternate Mode for video output. Without that capability the HDMI port will remain inactive regardless of the operating system or Thunderbolt 3 support. Check the laptop manual for Alt Mode confirmation before purchase.

Questions about this item

How do I install the UD-CUBE and what step is often missed?

Connect the dock to a USB-C port that supports DisplayPort Alternate Mode, then attach the HDMI monitor and peripherals; the step often missed is confirming the host port supports Alternate Mode video.

What maintenance or replacement will the UD-CUBE need later?

The dock has no user-serviceable parts or consumables; if the USB-C cable or HDMI connector wears out, the entire unit would need replacement.

What limit appears first during sustained use of the UD-CUBE?

The HDMI output is limited to 4K at 30Hz, so extended sessions at that resolution will hit the refresh-rate ceiling before other interfaces saturate.
