✓ What We Love

  • 18 ports including 3x Thunderbolt 4/USB4, 2.5G Ethernet, 5x USB-A, SD card and more
  • 98W host charging powers most modern MacBook Pros and Dell/HP laptops
  • Thunderbolt 4 certified — reliable, high-bandwidth passthrough for eGPUs and fast storage
  • Vertical orientation saves desk space; DisplayPort 1.4 and HDMI 2.0 display outputs
  • Rock-solid driver support on Mac and Windows

! Worth Knowing

  • Premium price — among the most expensive Thunderbolt 4 docks
  • Requires a Thunderbolt 4 or USB4 port on the host laptop to achieve maximum performance

The CalDigit TS4 has become the reference Thunderbolt 4 dock for a reason: it offers more ports than any competing dock at its tier while maintaining the reliability and build quality that CalDigit is known for.

The port count is genuinely comprehensive: 3× Thunderbolt 4/USB4 (40Gbps each), 1× Thunderbolt 4 host, 5× USB-A (10Gbps), 1× USB-A (7.5W charging), 2× USB-C (10Gbps), 2.5G Ethernet, 1× DisplayPort 1.4, 1× HDMI 2.0, 1× 3.5mm audio in, 1× 3.5mm audio out, SD 4.0 UHS-II, and a DC power barrel. The 2.5G Ethernet is particularly valuable for users with multi-gig NAS or broadband connections.

The 98W host charging handles the majority of modern laptops. Most MacBook Pro models and recent Windows ultrabooks charge at full speed through the Thunderbolt cable, meaning one cable from the dock to the laptop handles power, display output, data to peripherals, and network simultaneously.

Thunderbolt 4 certification matters for reliability. Many cheaper USB-C docks that claim Thunderbolt compatibility have bandwidth limitations or stability issues. The TS4's TB4 certification guarantees consistent 40Gbps throughput to Thunderbolt peripherals and daisychain compatibility.

The vertical orientation is a considered design choice that minimises desk footprint. Build quality is excellent — aluminium chassis, solid connections, no flex or wobble. CalDigit backs it with a 3-year warranty.

For professionals who use a laptop as their primary workstation and want a single-cable docking solution, the TS4 is the definitive choice.

Frequently Asked Questions

Does it work with a MacBook Pro?
Yes — the TS4 is specifically optimised for Apple Silicon and Intel MacBook Pros. macOS driver support is excellent.
Can I connect two 4K monitors?
Yes — the DisplayPort 1.4 and HDMI 2.0 outputs support dual 4K@60Hz displays. Some configurations (MST) require display compatibility.
Does it work with USB-C laptops that aren't Thunderbolt 4?
Yes — with reduced bandwidth. USB-C 3.2 Gen 2 laptops can use most ports but won't achieve full 40Gbps throughput to Thunderbolt peripherals.
Is a power supply included?
Yes — the TS4 includes a 230W power brick. The dock draws power from this to supply 98W charging to the host plus power to all peripherals.
