Oh, an important exception or two. MANY power supplies for computers

the most obvious.

I've found all modern wall warts (so far) are rated 110/220, 60Hz/50Hz
and auto switch. My mill DRO, computers, laptop PS, and a host of other
times, will just need plug adapters.

BTW, I took two computers back last time, an older HP for her folks, and
a fairly nice Dell I built up out of a yard sale score. The one for her
folks, I set to 220 here. But hers, I was installing software and
setting up the night before we left. Yup, forgot to switch the PS to 220.

Let me tell you, that's one HELL of a bang when a 110 PS gets socked
with 220! Needless to say, it died an instantaneous death. Luckily the
PS out of her old computer was a match, and the computer itself was fine.
