The One-Cable Desk: CalDigit TS4 Thunderbolt 4 Dock, Spec by Spec
Eighteen ports, 98 watts of host charging, and one cable between your laptop and everything else. Here's the complete spec rundown on the dock that wants to end your cable chaos.
Why Docks Win in 2026
Laptops keep getting thinner while desks keep getting hungrier: external monitors, fast storage, wired networking, card readers, audio interfaces. A full-spec Thunderbolt 4 dock folds all of it — plus charging — into a single plug. The CalDigit TS4 is the benchmark everyone else gets measured against.
The 18-Port Map
| Port | Count / Detail |
|---|---|
| Thunderbolt 4 (40Gb/s) | 3x |
| USB-C | 3x |
| USB-A | 5x |
| DisplayPort 1.4 | 1x |
| SD / microSD card slots | UHS-II |
| Ethernet | 2.5GbE |
| Audio | Combo in/out |
That's the full 18-port complement: every peripheral you own plugs in once and stays put.
Power & Charging: 98W on One Cable
- Up to 98W host charging delivered over the single Thunderbolt cable
- Ships with its own 230W power supply, so the dock never starves your peripherals to feed the laptop

- Thunderbolt 4 bandwidth (40Gb/s) keeps high-refresh and high-res panels fed without compression tricks
- Backed by a 2-year warranty
