The Anker 555 USB-C Hub offers a compact solution for creatives needing multiple connections, with Fstoppers praising its 4K 60Hz HDMI output and PC Tech Bits noting its reliable data transfer speeds.

The CalDigit TS4 Thunderbolt Dock earns its reputation as a gold standard in the category, offering exceptional portability and connectivity for demanding Mac users. TechRadar praised its robust aluminum build and 18-port configuration with 98W power delivery, while MacRumors noted its impressive 6K display support and 2.5Gb Ethernet. However, both reviewers acknowledged the $399.99 price tag as a significant drawback. The dock's lack of HDMI output is also a notable limitation for users requiring that connection type. This product is ideal for professionals needing extensive connectivity but may not suit budget-conscious consumers or those without Thunderbolt laptops.

Strengths
  • — Incredible 98W power delivery supporting fast charging for laptops and peripherals
  • — Fantastic port options with 18 total ports including 3x 10Gb/s USB-C, 5x 10Gb/s USB-A, and dual 6K displays support
  • — Extra Thunderbolt 4 ports providing high-speed data transfer and device connectivity
Watch-outs
  • — High price point at $399.99 making it expensive compared to alternatives
  • — No HDMI port which may limit compatibility with some displays

How they stack up

Anker 555 8-in-1 USB-C Hub

The Anker 555 8-in-1 Hub is more compact and affordable than the CalDigit TS4, but lacks the 98W power delivery and 18-port configuration that makes the CalDigit a powerhouse for demanding users. Compared to the Plugable USBC-9IN1E, it offers more ports and better charging capabilities, though the Plugable has a more plug-and-play design and doesn't require a separate power adapter. Unlike the Anker 563, it provides better HDMI output and pass-through charging but is less versatile in terms of port variety.

CalDigit TS4 Thunderbolt 4

The CalDigit TS4 Thunderbolt 4 stands out with its 18-port configuration and 98W power delivery, making it superior to the Anker 563 10-in-1 Docking Station which only offers 100W charging and fewer ports. Unlike the UGREEN Revodok Max, it provides better overall connectivity with dual 6K display support and no HDMI limitations, though it's significantly more expensive at $399.99. Compared to the Dell WD25TB4, it offers more universal compatibility and better port variety, but lacks the modular upgrade system that Dell's dock provides.
