    First please forgive my very limited knowledge of electronics.

    I live in Canada and am looking for a universal converter/adapter/
    transformer (not sure of the term) to replace all the adapters for my
    electric stuff (electronic scale, spotlight, rechargeable tools,
    etc.). I am wondering what I should buy.

    I am very confused about the numbers I see in the Input and Output
    sections of the different adapters that I use.

    - For the Input section, some of the adapters show only Voltage
    while others show Voltage AND Watts.

    - For the Output section, Voltage and Amps seem to always there.

    Is there a universal adapter that can handle every possible
    combination? A good place to buy it?

    Is it important to have a universal adapter that can handle different
    wattages, os are the Voltage and the Amps the only important numbers?

    Thank you.

    ** No such animal exists or could ever be made.

    The variety of technical requirements is HUGE so it is essential the
    dedicated AC supplies be made and employed in each case.

    I live in Canada and am looking for a universal converter/adapter/
    Try Kensington's travel adapter (not sure of trade mark and/or shelf-name)
    but you can find it in any computer store, laptop batteries/mobile
    accessories section.

    ** Huh ??

    Did you read the question at all ??

  5. For each device, you need an AC power adaptor that will supply the
    correct voltage, and _at least_ the required current (amps).

    Since various devices require various different voltages, it is not
    possible to make a simple universal do-everything AC adaptor. Any
    such adaptor would require a voltage selection switch to allow the
    user to set the voltage as needed (with a considerable chance of
    serious damage to the device being powered if the voltage is set

    It is not just the voltage there is the question of power. There is i have one small transformer that can be switched from 120v to 240v ac and the output range is 1.5. 4.5, 9. and 18v ac so what it all means. can it naybe used for all those voltage range absolutely not. The only way can it be valid is if the power of the device is much larger then the load.

    Thank you everyone for your input. I will stop looking for that beast
    which does not exist !
