Dell Pro Thunderbolt 4 Dock (WD25TB4) review

The Dell Pro Thunderbolt 4 Dock (WD25TB4) replaces the WD22TB4 on Dell's US store and ranks second. Dell lists 130W of power delivery for Dell systems and 96W for other laptops, support for up to four displays at 4K 60Hz, dual 6K 60Hz or a single 8K 60Hz screen, and 2.5 Gigabit Ethernet. The port set is two downstream Thunderbolt 4 ports, four USB-A 3.2 Gen 2 ports, one USB-C 3.2 Gen 2 port and one USB-C DisplayPort port, and every port supplies power whether or not a PC is attached. Business features include MAC address pass-through, PXE boot and Wake-on-LAN, and the warranty runs 3 years. The trade-offs are that non-Dell laptops lose the 130W headroom and the dock has fewer USB ports than the CalDigit TS4. It costs $299.99 on Dell's US store. We compared documented features and published prices and did not test the dock.
