CalDigit TS4 is a Thunderbolt 4 docking station with 18 ports. It's for Mac laptop users who want one cable to charge their machine and connect displays, storage, networking, and accessories.

**Key features:**

- Charge your laptop with up to 98W of sustained power that doesn't drop as more devices are connected.
- Connect devices to three 40Gb/s Thunderbolt 4/USB4 ports, one of which is a rear host port.
- Plug in accessories via eight 10Gb/s USB-A and USB-C ports, including a front USB-C port with 20W of power.
- Drive a single 8K display or dual 6K 60Hz displays on supported Macs via DisplayPort 1.4 and Thunderbolt.
- Get faster wired networking from the 2.5 Gigabit Ethernet port.
- Read cards in the front UHS-II SD 4.0 and microSD 4.0 slots.
- Charge phones and tablets from several ports even when no computer is connected.

Works with Thunderbolt 3, 4, and 5, USB4, and USB-C computers, including Intel and Apple silicon Macs, and requires macOS 11.4 or later. Dual displays need an M-series Pro, Max, or Ultra chip, an M4 or M5 base chip, or an Intel Mac; base M1, M2, and M3 Macs support only one external display through the dock. It also has audio in and out ports and a security lock slot, and comes with a 2-year warranty.
