The pinout is fine. You can charge a Switch with random adapters fine, powering docked mode is trickier because older PD adapters don't support it but newer ones do. The Switch adapter will happily charge my phone, tablet, eReader, etc and I have used it as my only charger on trips where I don't bring a laptop. Perhaps the problem here is OnePlus and whatever THEY do to get their fast charging spec? Nintendo did more non-standard stuff with the dock port dimensions. Not so much pinouts. 3rd party docks fried Switches because of shit power management sending more voltage than the Switch needed. EDIT: The problem seems to actually be that the Switch charger only supports 5V 1.5A whereas some phones require 2 or 3A and are not compatible.
