CalDigit TS4 Thunderbolt Station 4 review

The CalDigit TS4 has the most ports of any dock here: CalDigit lists 18, including three Thunderbolt 4 ports, three 10Gb/s USB-C ports, five 10Gb/s USB-A ports, one DisplayPort 1.4 output, UHS-II SD and microSD readers, three audio jacks and 2.5 Gigabit Ethernet. It sends up to 98W to the laptop and ships with a 230W power supply and a 0.8 m Thunderbolt 4 cable. CalDigit says it drives dual 6K 60Hz displays on M1 Pro and M1 Max Macs and dual 4K 60Hz on Intel Macs, Windows and ChromeOS. Two things keep it from first place. It costs $379.99, $90 more than the Plugable TBT4-UDZ, and it has only one dedicated video port, so a second monitor goes through a Thunderbolt port. CalDigit also notes the 2.5GbE port needs a Thunderbolt host. The warranty is 2 years. We compared documented features and published prices and did not test the dock.
