If anyone is interested in the actual technical details, check out the docs here: http://www.usb.org/developers/docs/ http://www.usb.org/developers/docs/ There's a 37.7MB zip and the USB PD specification (328 pages) is packaged within. In order to ensure shit doesn't melt, they'll have detectable cables for >5V and >1.5A operation. I'm reading the spec to find out how they plan to do cable detection. IC based, or electrical connections, or maybe something else?
