Using 115 volt (60 hertz) Wall Warts on 230 volts (50 hertz)

[Terry]

Moving from North America 115 volt 60 hertz outlets to a country
where voltage is 230v 50 hertz.
Pondering a good way to power some some items that use low
voltage (e.g. 4 to 9 volt 300 to 500 milliamp output) from wall
warts without dragging around a heavy step down transformer or
variac?
Would welcome any suggestions; we presume that a typical WW has a
low VA step down transformer and contains a half wave or full
wave rectifier and some 'smoothing' capacitors?
TIA. Terry.

Don't bother. Just leave the wall warts here and buy new ones in
the 230V country.

Have Fun!

Terry,

I cann imagine some possibilities but all of them are more expensive and/or
dangerous then buying some new wall warts

BTW. Even if you use a step down transformer you may run into trouble.
Transformers designed to run 60Hz may not like 50Hz. Especially cheap ones
may become saturated and very hot.
