A USB-A port (10Gbps), UHS-II SD and microSD card readers, and the aforementioned 3.5mm audio combo jack round out the front I/O. The front of the TS4 offers another two USB-C ports (10Gbps), one with 20W of charging power and the other with the standard 7.5W.

The dock's AC adapter plugs into the back of the dock, and there's a Kensington lock slot for added security if you're using the dock in an office space. You can quickly plug in a headset for voice and audio as needed, but using the front combo port will disable the rear in and out ports. There is alternatively a 3.5mm audio combination jack on the front of the dock for convenience's sake. A 2.5 Gigabit Ethernet port ensures you're getting the absolute fastest wired internet connection, and 3.5mm audio in and out ports are available for more permanent setups that have separate audio and microphone hardware (or a split headset connection).Ĭertain USB-A and USB-C ports deliver power even when there's no host laptop connected to the dock.

I don't mind this decision at all, and it works perfectly for my setup. Why not three? CalDigit sacrificed one of them to add a DisplayPort 1.4 hookup owing to the fact that it believes most people are going to be using the dock with a monitor anyway. Surrounding it are two more downstream Thunderbolt 4 ports. Like the TS3 Plus, the host port is located on the back of the dock.

There are 18 total connections to work with including the host Thunderbolt 4 port.

And since the TS4 is easily used standing up, it can actually take up less space on your desk than the competition.ĬalDigit has outdone itself when it comes to port selection. Compared to other popular Thunderbolt 4 docks that use a flatter, more rectangular shape, the total area isn't that much greater. The TS4 is taller, wider, and deeper than the TS3 Plus. There is a built-in rubber pad on the vertical "bottom" for better grip on a desk, and the package comes with some extra rubber strips that can be inserted into the side panel's ribbing if you're using the dock horizontally.

The dock works both vertically and horizontally. The TS4's 18 total ports offer the best connectivity of any Thunderbolt 4 dock on the market. Three sides of the dock have ribbed aluminum panels for better heat dissipation they also lend the dock a bit of extra aesthetic appeal. The chassis is made up of three solid pieces of aluminum, held together by four hefty screws on the back panel. The CalDigit TS4 follows the same design of the TS3 Plus, which was released in 2018.
