The OWC 11-Port Thunderbolt 4 Dock (OWCTB4DOCK) is a compact Thunderbolt 4 dock with an unusually large downstream Thunderbolt 4 port count — three TB4 ports for peripherals or display expansion alongside the host connection. It delivers 96W of charging to the connected laptop and supports single 8K, dual 5K, or dual 4K display configurations. The front-panel UHS-II SD card reader hits 312 MB/s and a 3.5mm audio combo jack handles both input and output. The four USB ports (3x USB-A Gen 2 + 1x USB-A 2.0) offer wide compatibility, though there are no dedicated HDMI or DisplayPort outputs — video requires a Thunderbolt or USB-C to display adapter.
OWC’s 11-port Thunderbolt 4 dock with 96W PD, 3x TB4 downstream, UHS-II SD card reader, 4x USB-A, and Gigabit Ethernet. No HDMI or DP ports.
