  • Three downstream Thunderbolt ports each deliver 15W charging for connected devices while supporting daisy-chaining up to five peripherals
  • Front-facing host port includes a 2.6 ft Thunderbolt 4 cable for simple deployment and secure placement

Thunderbolt 4 docking station

The StarTech TB4CDOCK is a Thunderbolt 4 certified docking station that expands a single Thunderbolt 4, Thunderbolt 3, or USB4 port into multiple high-speed connections. It provides 65 W host charging for compatible Windows laptops and MacBooks running macOS 11 or later. The unit includes a 2.6 ft Thunderbolt 4 cable and Kensington-style security slots for physical security.

Suits single-cable setups not multi-host users

This dock suits professionals who need one cable to connect dual 4K displays, high-speed storage, and peripherals while charging their laptop. It works with Thunderbolt 3 M1 or Intel Macs and Thunderbolt 4 or USB4 Windows devices. Buyers whose laptops lack Thunderbolt or USB4 host ports cannot use this dock and should consider USB-C alternatives instead.

65 W host charging decides compatibility

The dock delivers up to 65 W of power to the host computer through the Thunderbolt 4 connection. This single specification determines whether your laptop will charge while docked; systems requiring more than 65 W will not receive full charging performance from this unit. Check your laptop's power requirements before purchasing.

Questions about this item

How do I install the StarTech TB4CDOCK and what step is often missed?

Connect the included 2.6 ft Thunderbolt 4 cable to the front-facing host port on the dock and to your laptop's Thunderbolt 4, Thunderbolt 3 or USB4 port; the step often missed is ensuring the laptop port supports host charging and video output.

What maintenance or replacement will the TB4CDOCK need later?

The dock has no user-serviceable parts or replaceable modules; keep the Thunderbolt 4 cable and front host port free of debris and ensure firmware updates are applied through the host OS when released by StarTech.

What limit appears first on the TB4CDOCK under sustained heavy I/O?

The shared upstream bandwidth of the single Thunderbolt 4 host connection becomes the bottleneck before the downstream 10 Gbps USB 3.2 Gen 2 Type-A ports or the 15 W per Thunderbolt 4 downstream port limits are reached.
