Dell Thunderbolt Dock WD22TB4 - Modular 130W Docking Solution

In this review the Dell Thunderbolt Dock WD22TB4 comes across as a practical, future-focused dock for power users who need a clean single-cable workspace and strong power delivery. The single biggest reason to consider it is the combination of a swappable modular design and up to 130W power delivery, which lets compatible laptops charge quickly while driving multiple high-resolution displays and Thunderbolt peripherals. For anyone upgrading an office setup or centralizing cables, this dock simplifies connectivity without sacrificing speed.

Key Features

• Modular design: The swappable module lets IT teams upgrade connectivity options without replacing the entire dock, extending the product lifecycle.
• Dual Thunderbolt 4 ports: Two Thunderbolt 4 connections provide flexibility for high-speed peripherals and daisy-chaining compatible devices.
• Comprehensive ports: A mix of USB-C, USB-A, DisplayPort, HDMI and Gigabit Ethernet supports a wide range of monitors and accessories for a streamlined desk.
• ExpressCharge technology: Delivers fast charging on Dell systems, reaching up to 80% in about one hour to reduce downtime between meetings.
• High bandwidth: Thunderbolt links support up to 40 Gb/s transfer speeds so external drives and displays perform at their best.
• Included bundle: Ships with two DisplayPort cables, an HDMI cable, wire straps and a cleaning kit to get a multi-monitor setup ready out of the box.

Who It's For

The WD22TB4 is well suited to power users, small office IT teams and professionals who run multiple 4K displays or use bandwidth-hungry Thunderbolt peripherals and want a neat, single-cable docking solution. It is particularly useful when fast charging and a broad set of ports are a priority.

Those who should look elsewhere include users with only basic USB needs and no external displays, since a high-end Thunderbolt dock may be overkill, and owners of laptops incompatible with Dell ExpressCharge or that cannot accept 130W may not get the full benefit.
