There is another often overlooked difference. Here in the US we have 60 Hz
in our outlets. The rest of the world has 50. Properly made transformer with
100V 50Hz primary will work without a hitch on 117V 60Hz. It'll be
outputting circa 20% higher voltage that it's supposed to on the secondary
side but this is another question
