Thunderbolt 4 Dock

The full 40Gbps Thunderbolt 4 host connection provides the bandwidth backbone, with three USB-A ports running at USB 3.2 Gen 2 (10Gbps) rates and a Gigabit Ethernet port covering wired networking.

The single Thunderbolt 4 downstream port is the primary gap vs. the CalDigit TS4, which provides two TB4 downstream ports. Users who need to daisy-chain TB4 devices or run two simultaneously TB4-connected displays should look at the TS4. For the majority of single-monitor home office setups with one TB4 device, the single downstream port is sufficient.

Bottom line: Full TB4 40Gbps host link with 10Gbps USB-A. The single TB4 downstream port is the main limitation vs. the CalDigit TS4.

Dual 4K at 60Hz simultaneous via the TB4 downstream port and HDMI 2.0 port covers the standard two-monitor home office configuration. The HDMI 2.0 port limits output to 4K at 60Hz — users running 5K or 5K2K displays must connect those directly to the laptop’s TB4 port rather than through the dock's HDMI.

Bottom line: Dual 4K at 60Hz covers most home office setups. 5K display users need a direct laptop TB connection.

60W USB Power Delivery covers the standard charging requirement for most thin-and-light laptops. MacBook Air, MacBook Pro 14", and most Windows ultrabooks receive adequate charge rates during typical home office workloads.

MacBook Pro 16" users under heavy CPU and GPU load may see the battery replenish at idle but not fully maintain charge rate at peak draw. For document and communication work on a 16", 60W is adequate. The 135W external adapter provides sufficient headroom for the dock's USB ports alongside the 60W laptop allocation.

Bottom line: 60W covers most laptops. MacBook Pro 16" users under heavy GPU load may see slower charge rates.

Eleven total ports gives the OWC TB4 Dock one of the fuller port rosters in our rankings. Three USB-A 3.2 Gen 2 ports directly accommodate legacy peripherals — USB drives, printers, audio interfaces — without additional hubs. The SD 4.0 card reader handles UHS-II cards and works as a primary photo transfer workflow, and a 3.5mm combo jack rounds out the selection.

Bottom line: Strong 11-port selection with three USB-A and UHS-II SD — one of the fuller port rosters in our rankings.

The OWC TB4 Dock sits in the competitive mid-tier of the TB4 dock market below the CalDigit TS4. For users who don’t need the TS4’s second TB4 downstream port, the OWC represents a meaningful cost reduction for a functionally equivalent setup in most home office configurations.

Bottom line: Good value for single-monitor home offices. Multi-TB4-device users should evaluate the CalDigit TS4.

OWC has built Thunderbolt accessories since the TB1 era and its TB4 implementation is among the most reliable in the Mac ecosystem. Compact aluminum chassis with active cooling adds a low hum that is perceptible in a completely silent environment.

OWC’s Mac-first development means macOS compatibility issues that occasionally affect third-party docks — driver conflicts, wake-from-sleep failures — are less common than with competitors. Windows TB4 support is certified and functional, though Mac-side documentation and community resources are more mature.

Bottom line: Among the most reliable TB4 implementations for Mac. Windows support is solid but Mac-first development shows.
