The CalDigit TS4 is a Thunderbolt 4 docking station confirmed to offer an extensive array of 18 ports, providing a comprehensive set of connectivity options to users needing to connect multiple peripherals. One of its notable capabilities is delivering up to 98 watts of charging power to the host device, which supports powering and charging many laptops and Thunderbolt-enabled computers effectively. This level of power delivery often meets or exceeds requirements for many professional laptops, minimizing the need for separate power adapters for the host machine during use. The official CalDigit product page states these specifications, confirming both the number of ports and the host charging capacity: "Thunderbolt 4 dock with 18 ports and up to 98W host charging" and "Ports: 18" alongside "HostCharging: Up to 98W" (Source: https://www.caldigit.com/thunderbolt-station-4/).
In terms of power supply, independent verification from Aztek Computers on October 10, 2026, identifies that the CalDigit TS4 package includes a 230W power supply unit. This corroborates the capability of delivering the stated power to the host and peripherals. The exact model identity of the CalDigit TS4 has been confirmed by linking the ASIN B09GK8LBWS with the model TS4-US and UPC 4711233240793. Additionally, this record distinguishes the TS4 from other CalDigit dock models such as the TS3 Plus or TS5, ensuring users seeking this specific dock have clear validation of the product's identity (Source: https://www.aztekcomputers.com/ts4-us-ts4-thunderbolt-4-dock-with-230w-psu-caldigit/p).
While the number of ports is documented, the product materials reviewed do not specify the exact types or functions of these 18 ports. Without detail on which ports are included—such as USB Type-A, USB-C, DisplayPort, Ethernet, audio jacks, or card readers—shoppers cannot precisely determine the dock’s compatibility with their peripherals or assess the variety of devices it supports. Similarly, there is no explicit information on physical dimensions or weight, which could influence user decisions related to desk space and portability.
Further, the manufacturer and merchant sources do not list supported host operating systems. Users cannot conclusively know if the TS4 is fully compatible with Windows, macOS, or other systems from the available evidence. There is also no mention of compatibility with specific branded devices, which might be relevant for environments standardized on certain laptops or tablets.
Additional advanced features that some docks offer, such as security measures, bundled software utilities, or firmware update options, are not described in the available product information. Buyers interested in such features may need to seek clarifications directly from the manufacturer or authorized dealers.
In summary, the CalDigit TS4 offers a verified high port count with substantial power delivery, making it potentially suitable for users requiring extensive peripheral connectivity with robust charging. However, the absence of detailed port configuration, compatibility data, and feature descriptions means shoppers must inquire further or consult additional reviews and specifications to confirm that this dock meets their exact use cases and environment requirements.
