What he said was the "gadgets" today are dual, NOT the electric supply

I have some (newer, IIRC) power adapters that are marked "Input:
100-240VAC".
And I also have some very recent devices that say "input 120 volts
60 hz" which would not work properly even with a trransformer (they
would draw too much current on 50hz)
Virtually all 100-240 devices will work equally well on 50 or 60 hz.
