Plugable specifies USB Battery Charging 1.2 support on the TBT3-UDV's single front USB 3.0 port. That port supplies up to 1.5A at 5V, while the four rear ports supply standard USB 3.0 power. Choosing a port therefore affects charging behavior as well as cable placement.

The dock does not act as an independent charger when its host is disconnected, powered off, or asleep. Plugable recommends a dedicated charger for that use. Include this limitation when planning a desk that needs to charge phones overnight without leaving its laptop active and connected to the docking station.
