About the docking station USB-C ports
Not all USB-C ports support the full functionality of the USB Type-C standard. Some
ports might only provide data transfer, and might not support video (DP Alt Mode).
This docking station includes a Thunderbolt 3 port with a USB Type-C connector and a
USB 3.0 port with a USB Type-C connector.
The Thunderbolt 3 port can be used as a Thunderbolt 3 port or as a USB-C port.
When used as a USB-C port, you connect peripherals using USB 3.1 Gen 2 (10Gbps)
technology. These ports supports DP Alt Mode and 15W USB Power Delivery.
The USB Type-C Port (USB 3.0 - 5Gbps) is a standard USB 3.0 throughput port and can
only be used for peripherals supporting USB 3.0 (5Gbps) technology.
About the docking station ports
The four USB Type-A (USB 3.0) ports and one USB Type-C port located on the back
of the docking station are standard USB 3.0 throughput ports. When the dock is
connected to a laptop, this port provides a standard USB 3.0 power output to power or
charge your devices.
The front USB-A (USB 3.0) port is compliant with Battery Charging Specication
Revision 1.2 (BC 1.2), which means that you can use the port to charge a device faster
than you can using a standard USB 3.0 port. This front USB 3.0 port can fast-charge a
connected device, even when the dock isn’t connected to a laptop. When the docking
station is connected to a laptop, the front USB 3.0 port functions as a Charging
Downstream Port (CDP), which has simultaneous charge and sync capabilities.
The provided power adapter must always be connected to the dock in order to charge
a device using the Battery Charge 1.2 compatible USB 3.0 Type-A port. It can only fast-
charge devices that comply with USB Battery Charging Specication Revision 1.2.
