    I don't know the relationships between the voltages and current in multi-voltage adaptors.

    For example, "Masterplug 1200mA Multi Voltage Adaptor" can output 3, 4, 5, 6, 7.5, 9 or 12V.

    Is the 1200mA for every voltage (3, 4, 5, 6, 7.5, 9 or 12V), or only for the 3v? or 12v? If it is for 3v, then when I use for 6v, does it mean the (maximum?) current will be 600mA. If it is for 12v, does it mean the (maximum?) current is 2400mA on 6v ?

    Yes, it is the maximum current which the adaptor can supply at any of the outputs.

    Otherwise it would state a maximum power rating, rather than a current maximum.
