Satechi Thunderbolt 4 Dock — 100W Charging, Dual 4K/60Hz HDMI, 40Gbps Data

Meet the Satechi Thunderbolt 4 Dock, a versatile hub built for modern workspaces. It balances speed with flexibility, letting you power your laptop and connect multiple displays and peripherals from a single, tidy connection.

Power and speed are at the core of this dock. A USB-C PD port supplies up to 100W to charge your device while you work, and three Thunderbolt 4 ports push data and video with up to 40Gbps bandwidth. Two USB-A 3.2 ports offer high-speed access to external drives, keyboards, and peripherals. An Ethernet port provides a stable wired network when Wi‑Fi isn’t ideal.

Display, daisy-chain, and expandability

Designed for multi-monitor setups, the dock supports up to four external displays at 4K/60Hz. Two displays can run through Thunderbolt 4, and HDMI outputs can drive additional screens with the help of DisplayLink drivers. Note the Mac M2/M1 family may limit extended displays; in many setups you’ll typically see 1 via TB4 and 2 via HDMI, with DisplayLink enabling extra options.

• DisplayLink drivers unlock additional HDMI output options on supported systems.
• Mac users on M1/M2/M3 may experience a three-display limit depending on hardware.

Real-world workflows

In daily use, the dock helps you maintain a clean desk while expanding what you can work with. Connect a laptop, attach multiple displays, and transfer large files with high speed. The 1,000 Mbps Ethernet port keeps online calls steady, and the 100W USB-C PD turns charging into a seamless part of your setup. For creators and engineers, the ability to span timelines, references, and code across screens can feel practical rather than conceptual.

• Daisy-chain up to six devices for a tidy, scalable workspace.
• Thunderbolt 4 ports offer up to 40Gbps for fast data transfers and external GPU/SSD options.

What you get and durability

Each package includes a 1-meter Thunderbolt 4 cable, an 180W power adapter, a C5 power cord, and clear setup guidance. Satechi backs the product with a two-year limited warranty against manufacturing defects, giving you confidence for long-term use.
