The OWC Thunderbolt Dock can use Thunderbolt 4 to connect to and rapidly charge recent Mac's and Windows PC's that support Thunderbolt, enabling 40 Gb/s, USB4 (20 Gb/s) or 3.1 Gen 2 (10 Gb/s), USB Power Delivery and DisplayPort links between your computer and other Thunderbolt peripherals.

When connected to its own AC power supply, the OWC Thunderbolt Dock allows up to 90W power into its Thunderbolt 4 host port for charging the computer attached to the dock through USB Power Delivery 3.0. The other three Thunderbolt 4 ports can be used to link up multiple daisy chain connections while supplying 15W power for Thunderbolt / USB-C devices and drives. Each of these Thunderbolt 4 ports also enables up to two 4K displays or a single 5K, 6K or 8K display to be connected.

Let's have a closer look at the OWC Thunderbolt Dock upon purchase.

OWC shares a lot of technical detail about the features of each interface connector available on the dock.

The OWC Thunderbolt Dock comes with a Thunderbolt 4 cable, AC power adapter with power cord and instruction sheet. The Thunderbolt 4  cable should be used to connect the dock to the computer.

The 135W AC power adapter that came with the OWC Thunderbolt Dock connects to the DC power inlet on the dock. This power adapter provides power to the dock's electronics but also through the Thunderbolt and USB ports to the computer and peripherals.

The front of the OWC Thunderbolt Dock has a single Thunderbolt 4 port which is marked with a computer logo that should be used to connect to the computer for charging. There are also one USB 2.0 Type-A port, a 3.5mm headphone jack and a SD card slot.

The back of the OWC Thunderbolt Dock has three Thunderbolt 4 ports which are clearly labeled. There are also three USB 3.2 Gen 2 Type-A ports, a Gigabit Ethernet port and DC power inlet.
