The UD-7400PD can provide up to 140W of power to a computer that supports 140W (28V 5A) charging via standard USB-C Power Delivery. Computers not supporting 140W PD, or requiring proprietary signaling (e.g., Lenovo), will charge at up to 100W.

Please also note, the amount of power provided to charge the host computer can vary depending upon the number and type of peripherals connected to the dock and the amount of power those devices draw.

To put that another way, if several peripheral devices are connected to the dock that draw a significant amount of power, then as a result the amount of power provided to charge the host computer will be lower.
