The USB-PD standards are interesting.  Upon first reading about
them I was keen to find/design a device to just break out the
outputs and have a mini variable power supply for general use,
even battery powered from one of those power bank devices.  But as
with most things USB3/C it turns out the power supplies that are
actually available only implement the bare minimum range of
voltage outputs that the manufacturers think most people will
need.

 
Mine here are all 5/9/15/20V.  I "think" they're missing only 1 or
2 voltages, but that's enough for my laptops and cell phones.  Not
really sure what'd ask for 9 or 15 volts ...

9V plugpacks are pretty common for stuff I use, it's typical for
devices that reduce that to 5V internally.  Similarly 5V devices
generally use 3.3V internally.  My laptop's power supply is 16V, so
15V might work.

 
Not sure what a "9v plugpack" is -- maybe something leaning a little
more "professional grade", like what photographers tend to carry
about?

I interpreted "plugpack" in this context to be Kev's word for what most
of the rest of us refer to as a "wall-wart".
