Our take

What it's like to live with

The CalDigit TS4 Thunderbolt 4 Dock is a premium docking solution built for professionals who demand serious connectivity from a single cable. With eighteen ports packed into a compact aluminum chassis, it transforms any Thunderbolt 4 or USB4 laptop into a full workstation hub, supporting dual 6K displays or a single 8K monitor depending on your setup. The dock delivers up to 98W of power delivery through its host port, meaning most laptops, including power-hungry MacBook Pro models, can charge fully while connected, eliminating the need for a separate charger on your desk.

Beyond the headline Thunderbolt 4 ports, the TS4 includes five USB-A connections, an additional USB-C port, a 2.5GbE Ethernet jack for fast wired networking, UHS-II SD and CompactFlash card readers for content creators, and both digital and analog audio outputs. This breadth of connectivity makes it especially appealing to photographers, videographers, and developers who juggle external drives, card readers, and peripherals simultaneously. CalDigit also engineered the dock with a locking DC power connector and a sturdy build quality that resists the wobble and heat issues common in cheaper multiport hubs, ensuring stable performance during long work sessions or demanding data transfers.

Setting up a clean, efficient desk becomes simple with the TS4, since a single Thunderbolt 4 cable to your laptop unlocks the entire port array, reducing cable clutter while maximizing throughput. The inclusion of forward and backward compatibility with Thunderbolt 3 and USB4 devices gives it strong versatility across different hardware ecosystems. For remote workers, creative professionals, and anyone running a multi-monitor setup, the CalDigit TS4 earns its reputation as one of the most capable and reliable docking stations currently available, justifying its position as a long-term investment rather than a disposable accessory.
