Hi!
I was horrified that he hadn't checked the voltage the amperage or the
polarity. He knows more than me about computers, but was he right
to not check these things

No! You were *definitely* correct. I'm here to say that substituting laptop
power supplies between different models and makers (as long as the
connectors are completely compatible!) is generally OK as long as you have
checked the voltage (both listed and what is actually being put out when
unloaded), current rating and polarity *first*. The voltage should be exact
and the polarity had better match as well. Current supply can be higher or
equal to what the computer expects.

There is some leeway in most designs for current draw and possibly voltage,
but you can't always count on this and won't find it documented anywhere
short of personal experience.

If you don't check these factors before plugging things in, you're looking
at the possibility of causing anything from instant destruction on up to
slow cumulative damage to the computer.

Hi!
I had a 1960 five -or- six-transistor radio with an optional external
power cord/wire/plug-in device thingy. Matched perfectly with the
input of an immersion coffee re-heater, but that only worked once. :/

Hmm...impressive bang? Lots of smoke? Sudden bright light from within? Sound
output equivalent to a 1,000 watt home theater system but only for a second?

I think I saw geesus, but IIRC the smoke got out. I was probably after
the 1000 watt stereo effect, hell I was only a 9yo kid sniffing glue. [*]
And back then, we thought Mad magazine was an anarchist publication. ;)
