Smartlinx Thunderbolt 4 Dock – 21-Port Docking Station for MacBook Air/Pro (M1–M4), Windows & Chrome

Elevate your workstation with the Smartlinx Thunderbolt 4 Dock

The Smartlinx Thunderbolt 4 Dock is a 21-port docking station designed to transform a single laptop into a complete, easy-to-manage workspace. It pairs speed with versatility, giving you robust display options, fast data transfer, and reliable charging without the clutter of multiple adapters.

Compatibility and charging versatility

Built for machines with 8th Gen Intel processors or newer, this dock delivers a practical balance of power and connectivity. On older systems, some features may not be fully accessible due to hardware constraints. The dock provides USB-C power delivery with up to 90W for compatible laptops, while phones and tablets can benefit from 20W fast charging. For devices above 90W, charging behavior may vary, so it’s best paired with supported hardware.

Display options and performance

Designed for busy workflows, the dock offers 40Gbps bandwidth to support rich visuals and responsive peripherals. For display setups, macOS users (excluding M1 Macs) can run dual 4K at 60Hz, while Windows users can push up to 8K at 60Hz plus an additional 4K at 60Hz. This combination helps create expansive workspaces for editing, design, or coding tasks without sacrificing speed.

• Dual 4K@60Hz on macOS (excluding M1 Macs) for crisp, detailed screens
• Up to 8K@60Hz + 4K@60Hz on Windows for immersive multi-monitor setups
• 40Gbps data bandwidth supports fast transfers and broad peripheral compatibility

Power, data, and everyday use

Beyond video, a broad array of USB-C and USB-A ports, Ethernet, audio, and other essentials help you connect peripherals, storage devices, and accessories with ease. The included power path keeps compatible laptops charged while you work, and the hub remains a dependable anchor for a tidy, efficient desk setup.

• 60W base charging with up to 90W for supported laptops
• 20W fast charging for phones, tablets, and power banks
• 12-month warranty with accessible support via Amazon

Real-world benefits

Imagine a clean, organized desk where a single connection hub handles your laptop, two displays, external drives, and a keyboard.

While results vary by hardware, you may experience fewer cable tangles, more screen real estate, and flexible charging options as you switch between tasks.
