This dock contains two bi-directional 40 Gb/s Thunderbolt 3 ports, each of which utilizes the reversible USB Type-C connector and also supports 10 Gb/s USB 3.1 and dual-bandwidth DisplayPort 1.2, allowing you to connect up to two 4K/60 Hz displays simultaneously, or one 5K Thunderbolt 3 display. Additionally, you can daisy chain up to six devices from a single Thunderbolt 3 port.

To maintain compatibility with legacy devices, this dock also has five 5 Gb/s USB 3.0 ports, and one 800 Mb/s FireWire 800 port. The Mini DisplayPort shares the Thunderbolt 3 bus and allows a second display to be connected, while the 3.5mm audio in/out port allows external speakers, mics, and other audio equipment to be connected. Pro-grade digital audio output for a lossless signal transfer is accomplished using the S/PDIF output, network connectivity is achieved using the Gigabit Ethernet port, and the integrated SD card reader lets you download photos and videos from your digital camera or other device. Additionally, a power cable and 1.6' Thunderbolt 3 cable are included.
