Why don't these have a "volume" that goes to 16 volts?
Just a joke, most climate and media controls in my car go to eleven re "Spinal tap" movie.
On the same note, I repaired HP supplies decades a go, and most will have meters with a grey scale above the ratings.
The published specs are for at worst case situations, maybe 105 volts in, temperature, etc.
You could always go into the "11" area with totally no worries at 120 volts in.
Buy a cheap broken HP, come to the forum for help, If you get GAS.
Miss working on TE. Consumer crap makes me glad I'll die before I get older. If in my 20's now, would go nuts with today's future outlook.
