The TBT4-UDX1 can provide up to 96W of power to charge a compatible host computer.

The TBT4-UDX1 has two downstream Thunderbolt ports.  Each time a device is connected to one of these ports, the amount of power provided to the host computer is lowered by 15W.

For example, if there is one device connected to a downstream Thunderbolt port, the total amount of power provided to the host will be 81W.

If there are two devices connected to both downstream Thunderbolt ports, the total amount of power provided to the host will be 66W.
