With 40Gbps bandwidth, it supports single 8K/60Hz or dual 4K/60Hz displays, making it a strong choice for creative workflows and multi-monitor setups. The integrated 96W Power Delivery keeps your laptop charged while powering connected peripherals. This dock packs three downstream Thunderbolt 4 ports, four USB-A ports (one with BC 1.2 fast charging), gigabit Ethernet, an SD card reader, and a 3.5mm audio jack. An 80cm Thunderbolt 4 cable is included, and IT administrators will appreciate the MAC address pass-through and WiFi auto-switching features available through StarTech's Connectivity Tools.

Product Info

Released in 2022, the TB4CDOCK sits at the high end of the docking station market with an MSRP around ¥40,000–¥50,000. It comes with a 2-year warranty, an 80cm Thunderbolt 4 cable, and a 100W AC adapter. Availability is good through Japan and other major retailers. This is a top-tier Thunderbolt 4 dock aimed at professionals who need every feature: 8K output, 96W PD, three downstream TB4 ports, and enterprise-grade management tools. Direct competitors include the CalDigit TS4 and Belkin Connect Pro Thunderbolt 4 Dock.

Best Use Cases

Creative professionals and video editors: The ability to drive an 8K display or dual 4K monitors at 60Hz is ideal for high-resolution timelines and color-critical work. The 40Gbps bandwidth also means fast file transfers from external SSDs. Note that base M-series MacBooks are limited to single display output, so pair this dock with a Pro/Max model for full benefit. IT administrators and enterprise users: MAC address pass-through and WiFi auto-switching simplify network management across multiple laptops. This dock is overkill for home users who only need basic USB expansion; a simpler USB-C hub may be more cost-effective. * Users needing dual monitors plus wired LAN: If your workflow demands two external displays and a stable wired network connection, the TB4CDOCK delivers. Just verify that your host PC supports Thunderbolt 4 or USB4, otherwise video and charging performance may be limited.

Things to Consider

This dock is not compatible with Thunderbolt 3-only PCs in full capacity; while it may work as a USB4 device, video output and charging features could be restricted. The 96W PD is sufficient for most ultrabooks and MacBooks, but high-performance gaming laptops drawing 150W or more may not charge adequately. At around ¥40,000, it's a significant investment — if you don't need Thunderbolt 4's full feature set, a USB-C hub at half the price may serve you just as well. ## Alternatives
CalDigit TS4: The reigning champion of Thunderbolt 4 docks. It offers 98W PD, a built-in DisplayPort 1.4 port, and even more USB ports. It's slightly more expensive than the TB4CDOCK, but the dedicated DisplayPort output is a plus for users who prefer a direct video connection. Belkin Connect Pro Thunderbolt 4 Dock: Priced similarly, with 90W PD and DisplayPort 1.4. It has a sleek design popular among Mac users. The TB4CDOCK lacks DisplayPort but compensates with three downstream TB4 ports and an integrated SD card reader, making it more convenient for photographers and videographers who frequently transfer media.
