> retrofitting usb-c to anything?
Nah, you can retrofit USB-C to things, sort of.
Say you have something that takes a 5.5mm barrel connector and 12V @ 1A.
You can tell this thing to negotiate for 12V @ 1A, and if it can't get it, to give up.
In turn, it can power that device from many USB-C adapters.
You can buy much the same thing pre-assembled into a cable-- https://www.amazon.com/2-Pack-JacobsParts-Type-C-Trigger-Con...
(But the fpx thing makes safer choices, like letting you not connect the "wrong" voltage if the charger is not capable).
