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.

XDA Developer Cale Hunt emphasized that 'youve found it' when looking for the best Thunderbolt 4 dock, noting that it 'pushes everything to the max' with its port selection. The dock's design allows for both horizontal and vertical orientations, with included rubber bumpers for horizontal use, though MacRumors' Hartley Charlton noted the 'large power brick' that detracts from portability but is necessary for its function.

XDA Developer Cale Hunt highlighted that 'the TS4 is built into a rather compact aluminum case made up of three pieces held tightly together with screws,' and Tech Advisor's Simon Jary noted that 'the TS4 goes three better with a mighty 18' and that 'the dock also frees you from the vagaries of Wi-Fi with a wired Ethernet Internet connection.' The dock's design allows for both horizontal and vertical orientations, with included rubber bumpers for horizontal use, though MacRumors' Hartley Charlton noted the 'large power brick' that detracts from portability but is necessary for its function.
Performance and Real-World Testing
In real-world usage, the TS4 delivers consistent performance across its extensive port selection, with Thunderbolt 4 ports supporting 40Gbps bandwidth and USB ports offering up to 10Gbps transfer speeds. Digital Camera World's Paul Hatton confirmed that 'the TS4 performs well in every way from data transfer, charging of devices, and build quality,' while TechRadar's Collin Probst emphasized that 'it offers all the ports any modern desk may need while providing a reliable user experience.' The dock's Thunderbolt 4 ports support data transfer rates up to 40Gbps, with USB-A and USB-C ports supporting up to 10Gbps. XDA Developer Cale Hunt noted that 'the TS4 is more expensive than a lot of other Thunderbolt 4 docks in the same category, but it really does push everything to the max,' and Tech Advisor's Simon Jary highlighted that 'the TS4 goes three better with a mighty 18' and that 'the dock also frees you from the vagaries of Wi-Fi with a wired Ethernet Internet connection.' The dock's performance was also noted by MacRumors' Hartley Charlton, who stated that 'the Ethernet port provided exceptional performance, delivering the highest speeds observed from the router,' and TechRadar's Collin Probst who noted that 'it feels like something I can rely on for years to come.'
Where It Falls Short
Despite its many strengths, the CalDigit TS4 has several notable drawbacks that may deter some buyers. TechRadar's Collin Probst noted the 'High price' and 'Slightly bulky' nature of the dock, while Digital Camera World's Paul Hatton criticized the 'Large battery adapter' as a drawback. MacRumors' Hartley Charlton pointed out that 'an HDMI port is noticeably absent on the device, which may be a drawback for those who rely on HDMI for their display setup,' and TechAdvisor's Simon Jary noted that 'DisplayPort means just two downstream TB4 ports' as a limitation. Additionally, the dock's warranty is only two years, which is shorter than some competing docks. XDA Developer Cale Hunt noted that 'the TS4 is more expensive than a lot of other Thunderbolt 4 docks in the same category,' and TechRadar's Collin Probst emphasized that 'it has not solved every question from the TS3,' suggesting that while improvements were made, some issues persist. The 'large power brick' was also noted as a drawback by MacRumors' Hartley Charlton, who stated that 'the large power brick that detracts slightly from the portability of the device and is an important consideration in terms of cable management.'
Who It's Best For
The CalDigit TS4 Thunderbolt 4 dock is ideal for professionals who require extensive connectivity options and high-performance data transfer capabilities. TechRadar's Collin Probst stated that 'it offers all the ports any modern desk may need while providing a reliable user experience,' and Digital Camera World's Paul Hatton noted that 'the TS4 handles peripheral connection, device charging, and display extension like an absolute pro.' The dock is particularly suited for creative professionals who work with high-resolution displays, require multiple USB ports for legacy devices, and need robust charging capabilities for various peripherals. MacRumors' Hartley Charlton emphasized that 'the TS4 is a dock with 98W charging power and an impressive array of 18 ports, ideal for Mac setups with a wide range of connection requirements,' and TechAdvisor's Simon Jary noted that 'the TS4 goes three better with a mighty 18' and that 'the dock also frees you from the vagaries of Wi-Fi with a wired Ethernet Internet connection.' The dock's support for dual 6K displays at 60Hz and single 8K displays at 60Hz makes it particularly valuable for video editors, graphic designers, and other professionals who require high-resolution multi-monitor setups. However, the high price point and the absence of an HDMI port may make it less appealing to casual users or those on a budget.
Price and Value Considerations
The CalDigit TS4 Thunderbolt 4 dock retails for approximately $400, making it one of the most expensive Thunderbolt 4 docks on the market. TechRadar's Collin Probst noted that 'the TS4 stands out as an outstanding dock' and that 'it has finally earned a full 5-star review from TechRadar Pro,' despite its 'High price.' Digital Camera World's Paul Hatton called it 'the best Thunderbolt docking station but you definitely pay for it,' and XDA Developer Cale Hunt emphasized that 'the TS4 is more expensive than a lot of other Thunderbolt 4 docks in the same category, but it really does push everything to the max.' The dock's price reflects its comprehensive port selection, robust build quality, and high-performance capabilities, including 98W power delivery and support for up to two 6K displays at 60Hz. However, TechAdvisor's Simon Jary noted that 'the dock also frees you from the vagaries of Wi-Fi with a wired Ethernet Internet connection,' suggesting that the Ethernet support and overall connectivity make the price justifiable for professionals. The dock's two-year warranty is also shorter than some competing products, which may be a consideration for buyers seeking extended coverage. Despite the cost, the TS4's extensive port selection and performance make it a strong choice for users who need maximum connectivity and reliability.
