CalDigit’s TS4 defines what a Thunderbolt 4 dock should be: 18 ports, 98W upstream power delivery to a connected laptop, and simultaneous support for two 6K displays or four 4K displays from a single Thunderbolt 4 cable. For a MacBook Pro or Dell XPS 15 user who moves between desk and portable use, the TS4 means plugging in exactly one cable to connect to all monitors, storage, audio, and networking simultaneously.

The port selection is genuinely comprehensive: three Thunderbolt 4 ports (one upstream, two downstream for chaining or storage), five USB-A 3.2 Gen 2, three USB-C 3.2 Gen 2, SD 4.0 (UHS-II), microSD, 3.5mm audio I/O (separate headphone and mic), 2.5 Gbps ethernet, and DisplayPort 1.4. The aluminium chassis has a small footprint with the ports arranged so cable management is straightforward in both horizontal and vertical orientations.

98W power delivery is enough to charge a 14″ MacBook Pro at maximum rate and a 16″ MacBook Pro at close to maximum — the highest upstream PD available in a Thunderbolt 4 dock, and a meaningful advantage over competitors that cap at 85W. Setup is plug-and-play on macOS and Windows with no software required.
