USB-C Power Delivery (PD) is negotiated between the power-sourcing equipment (e.g., a dock or multiport hub) and the connected host device. During this negotiation, the device offering power communicates its capabilities, and the host determines whether it can accept the power. If the host does not support Power Delivery, no power will be sent to the computer over the USB-C connection. This will allow you to take advantage of other capabilities such as data transfer or video output without risking damage to the computer.
