The USB-C Power Delivery (PD) port on the OntheGo™ 7-in-1 Multiport Adapter is for charging only. It supports up to 100W of input and up to 80W of pass-through charging output, with about 20W used to power the hub itself. This port does not support video output, data transfer, CD/DVD drives, or the Apple SuperDrive. Avoid daisy-chaining this adapter with other hubs while it is connected.
