The usage current ( Amp )of your Electronic appliance is also very important
for selecting your step down transformer.

Hello,

I've imported an electronic aplliance from Japan
which comes with a charge-adapter. The adapter is
designed for Japanese power (100V/60Hz) and sockets.

I live in Europe and have 230V/50Hz. The charge-adapter
takes 100V @ 60 or 50 Hz. All AC-AC-transformers I've
seen so far here output 110V @ 60 Hz. Am I right
that I can use such transformers for my Japanese equipment ?

The descriptions of the transformers say all "for US appliances",
but in the US you have 120V/60Hz, don't you ? So the
transformers should be suitable for both US and Japanese
appliances to work with as the 110V are in
tolerance for both 100 and 120V ? (But don't probably
can use Japanese appliances with US power, do you ?).

Are Japanese and US wallsocket mechanically identical ?

Thanks,
Adrian
