What is the lowest voltage you have seen?
For me, 97 volts.

The thing about low voltages and electrioncs.
THough in days of old when folks were bold there were Radios and the like that actually operated on 120 volts rectified direcr. NO TRANSFORMNER actual line power and if you plugged the plug in and touched the chassis.. Depending on which way the plug (2 blade) was turned.. ZAPP... (you got bit) thankfully you don't see those any more save in vintage stuff. I mean very vintage .
Toay most everything runs on much lower voltages. and a Power supply converts 120 volt AC down to 4 or 12 or something DC. (Those are very common voltages One brand I know uses 14 volt)
THere are basically 3 types of power supplies.
Switching supplies.. If you fed one of those oh say 20 vols AC.. i should be able to deliver 12 VDC all day at full output and not overheat... OR you can feed it 250 volts. . And it will still output 12 VDC and not overheat.. It truly does not care so long as you are feeding it at least about 8 volts AC or more .
Transformer supplies There are types
Regulated SHUNT.. A lower supply voltagte they run cooler
Regulated PASS Same thing
Non Regulated or ferroresonant These may not deliver full output if the voltage drops. Many wal wart are of this type (Low power like phone chargers)
They also will not oveheat.
