..Anyone with any Acer model that supports Power Delivery?
I mean, from articles I have found about the USB3.1 and USB-C standards, it looks like also supporting PD is entirely up to the vendor.
The section "USB Type-C information" saying "Delivers up to 3 A at 5 V DC for USB charging", is the only point where the manual is referring to any direction of USB charging. Sad that the marketing department didn't want to be clear about this.
But, has anyone actually tried charging an Acer laptop using USB-C?
Not sure if testing will void warranty.
So I'd better conclude that the Swift 3 SF314-51-56Y4 does not support USB PD, ref http://www.usb.org/developers/powerdelivery/.
