Ranked #5 in Best Thunderbolt 4 Docks

Plugable TBT4-UDZ

4.0

2 sources$290as of Sep 25

The TBT4-UDZ is the do-everything alternative: a 16-in-1 dock with HDMI, DisplayPort 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, two of each
— 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 HDMI outputs 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.
