But I do have a couple of wall-wart powered devices

making inner conductor negative?) or voltage/current required.
It's a good thing that I've labeled them as such. Very often, the
"wart" bears some manufacturer ID (if any) that isn't related to the
brand of equipment that it's powering.
That's what a Brother P-Touch is good for.
Every wall wart should be labelled with the device that it is intended
for, to reunite when separated.
Also, every one should be labelled with voltage, amperage, AC/DC,
polarity, and even plug dimensions (5.5 x 2.5 looks a lot like 5.5 x 2.1!)
"Connectable" P-touch can be sent an icon for polarity, if anybody doesn't
understand "tip"/"ring"
There was a New Yorker cartoon, where the man with massive shelving units
full of wall warts tells his son that someday they will all be his.
I've got my "big box o' warts"
that range from 3VDC to 24VAC. I'm not
sure of what many of them were intended
to power at this point.
