I like Power Delivery alot. This Panasonic x86 Tablet uses a 16V DC barrel jack plug, but it also works with 15V DC from a USB Power Brick! 馃殌

@christian Agreed, PD was one of the most useful updates to the USB standard IMHO. I'm still looking at how to produce a variable +/- supply from one though.

@ChuckMcManis You mean PPS? Great Video from GreatScott: https://www.youtube.com/watch?v=kcmpGbR6xZc
USB-C Just got Even Better! (PPS)

@christian Nope, I'd like to generate +/- "v" from the source. So for example +15V in => + and - 10V out. There are plenty of circuits that will invert a positive voltage, but if you want to have similar impedance profiles on both the positive and negative side you need to get a bit fancier.
