Plugable TBT-UDM Thunderbolt 4 Dock
Part numberTBT-UDM
The short answer
Plugable's TBT-UDM Thunderbolt 4 Dock is a docking station for a mini PC owner whose machine has a Thunderbolt or USB4 port. It connects to the computer over Thunderbolt 4 and offers power delivery of 100 W.

Specifications
The part number is TBT-UDM. The host connection is Thunderbolt 4, so everything on the dock reaches your mini PC through a single cable to one port. A plain USB-C port without Thunderbolt or USB4 is not enough. Power delivery is 100 W, a figure worth weighing against your machine's own power needs if you plan to run it through the dock.

Which mini PCs it fits
The rule is simple: the dock connects over Thunderbolt 4, so the mini PC needs a USB4 or Thunderbolt port. It fits the ASUS ROG NUC 16 Edition 20, the Apple Mac Studio (M5 Max), the BOSGAME M5 and the Beelink SER8. It does not fit the ACEMAGIC K1 (Intel), the ASUS ExpertCenter PN65 or the Beelink EQ14, because none of them has a USB4 or Thunderbolt port. For the Beelink GTi14 Ultra and the GMKtec NucBox G10, we have not confirmed it fits, because their USB4 ports are not confirmed.

Before you buy
Before you buy, confirm that your mini PC has a USB4 or Thunderbolt port, because a machine without one cannot use this dock. Plugable does not state the dock's port selection or whether it has a network port, so check those before you plan around specific connections or wired networking.
Common questions
Will it work on a mini PC with only a regular USB-C port?
It needs a USB4 or Thunderbolt port. The ACEMAGIC K1 (Intel), the ASUS ExpertCenter PN65 and the Beelink EQ14 have neither, so the dock does not fit them.
Does the dock have an Ethernet port?
Plugable does not state whether the dock has a network port, and it does not state the port selection either, so check before relying on it for wired networking.
Which mini PCs does it fit?
It fits the BOSGAME M5 and the Beelink SER8, among others. For the Beelink GTi14 Ultra, we have not confirmed that it fits.
