    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!

  3. 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.
