The TBT4-UDZ is the do-everything alternative: a 16-in-1 dock with HDMI, DisplayPort, multiple Thunderbolt ports and a generous USB charging spread that earned Laptop Mag's 2025 Dock of the Year. Laptop Mag said it lands just shy of a 5-star score and is one of the best docks it has tested. It is pricier and bulkier than the UD5 sibling, but for a decked-out workstation it rivals the flagships.

Strengths
  • Huge 16-in-1 port selection rivaling the most loaded docks
  • Both HDMI and DisplayPort outputs plus multiple Thunderbolt ports
  • Many powered USB ports for charging accessories at the dock
Watch-outs
  • Falls just short of a 5-star score in expert testing
  • Larger footprint than slim docks like the Plugable TBT4-UD5
  • Pricier than the value TBT4-UD5 sibling

How they stack up

Plugable TBT4-UD5

The value alternative to the CalDigit TS4: it gives up some of the TS4's 18-port count and downstream Thunderbolt ports but adds dual HDMI the TS4 lacks, for roughly half the price. It is simpler than the Plugable TBT4-UDZ and Kensington SD5780T but covers the essentials most users need, undercutting the OWC Thunderbolt 4 Dock on price too.

Plugable TBT4-UDZ

The maximalist value play: it nearly matches the CalDigit TS4 on port count while adding both HDMI and DisplayPort the TS4 lacks, for less money. It is more loaded than its Plugable TBT4-UD5 sibling and the OWC Thunderbolt 4 Dock, and offers more total ports than the Kensington SD5780T, though it is bulkier and pricier than the UD5.
