Docking Station CalDigit CD-TS4-EU — Thunderbolt dock with 4 Thunderbolt ports and 2 USB-C ports

The CalDigit CD-TS4-EU is a Thunderbolt dock that expands a computer's connectivity with four Thunderbolt ports and two additional USB-C ports. Designed for workstations and laptops with Thunderbolt or USB-C support, it centralizes connections for displays, high-speed storage, audio interfaces, and other peripherals. The compact, bus-powered design simplifies cable management by allowing multiple devices to be connected through a single hub while preserving high data transfer rates and support for external monitors.

Advantages

The dock offers multiple Thunderbolt ports to daisy-chain devices and connect high-bandwidth peripherals without sacrificing performance. Integrated USB-C ports add flexibility for devices that use standard USB-C connections. The unit supports simultaneous use of several displays and external drives, reducing the need to swap cables frequently. Its sturdy build and consistent port layout make it suitable for both mobile and stationary setups that require predictable connectivity.

Suitable for

• Creative professionals using external displays and fast NVMe or Thunderbolt storage
• Office users who need multiple USB-C/Thunderbolt ports for docking laptops
• Engineers and developers connecting multiple peripherals such as audio interfaces, external GPUs, and network adapters
• Home offices that require simplified cable management and reliable device expansion

When it may not be suitable

The dock requires a host computer with Thunderbolt or USB-C support to provide full functionality; systems without Thunderbolt may not be able to use all ports at full bandwidth. It may be excessive for users who only need one or two additional USB ports or who do not use high-bandwidth peripherals. Power delivery capabilities depend on the specific laptop and cable used, so on some systems the dock may not provide enough charging power for heavy-duty laptops.

Key specifications

• Number of Thunderbolt ports: four Thunderbolt ports for host and downstream connections
• Number of USB-C ports: two USB-C ports for peripherals and charging-compatible devices
• Display support: supports multiple external displays via Thunderbolt/USB-C with compatible host and cables
• Data transfer: high-bandwidth Thunderbolt connectivity suitable for NVMe and other fast storage
• Form factor: compact desktop dock designed for workstation and laptop setups
• Compatibility: intended for computers with Thunderbolt/USB-C ports; functionality varies by OS and host capabilities

How to use

Connect the dock to a compatible laptop or workstation using a Thunderbolt or USB-C cable. Attach external monitors, storage devices, audio interfaces, and other peripherals to the available Thunderbolt and USB-C ports. If required, connect a power adapter and confirm power delivery negotiation between the dock and the host system. Use the host operating system’s display and device settings to configure multiple monitors, external drives, and network adapters as needed.

What to consider before purchase

• Confirm that your computer supports Thunderbolt or USB-C and verify the version and bandwidth available on your host ports
• Check the dock’s power delivery compatibility with your laptop if you require charging through the dock
• Ensure your monitors and cables support the desired resolutions and refresh rates when connected via Thunderbolt/USB-C
• Review operating system compatibility for functions like display chaining, device drivers, and network interfaces

Usage recommendations

For reliable performance, use certified Thunderbolt cables and keep host firmware and drivers up to date. When connecting multiple high-bandwidth devices (such as external NVMe drives and multiple 4K displays), verify host bandwidth limits and, if necessary, distribute devices across ports or use additional docks to maintain optimal transfer rates.
