I have an adaptor for a DAB digital radio, from Panasonic, that's quite big
and heavy, though its brand new.

Is it ok to use an older adaptor, that's quite small, but has the same
voltage?


Any help appreciated.

Thanks

As long as he voltage and current ratings are the same. You don't want to
use a unit that will not supply the necessary power to correctly operate
your equipment.

If I were you, I'd use the adapter that came with the unit. It's probably
bigger because it draws more current. Art is correct, and make damn sure
that the current rating (given in mA) on your small adapter either meets or
exceeds the rating on the big one. If the unit draws more current than the
little adapter can provide, it probably won't work for very long (if at all)
and you may even have a fire risk. It's OK to exceed the current rating,
but not the voltage. Sometimes you can get away with being off on the supply
voltage by 1 or 2 volts, but that should be a last resort. Finally, pay
close attention to the polarity of the connector, some are center-positive
but others are center-negative. Using the wrong connector to supply the
power could land the unit in the repair shop very quickly unless there is
built-in reverse-polarity protection.
