I wonder if someone can give me some advice please.
I have a device that needs a 9V DC power source - it can use batteries (6 x 1.5 AA batteries) - but batteries get to be a pain.
It says on the device that it needs 9v then it says 850mA.
I think the one that the manufacturer will proved as an expensive accessory is apparently 500mA.
I tried a Dick Smith adaptor (regulated) that can output 9V - it said it was 500mah and the device worked fine - I dont want to use that adaptor though.
I have found an adaptor that is 9v and says its "OUTPUT:9V 1000mA 9VA"
I would guess the last A probably refers to Adjusted? (ie regulated)
Now assuming I get the polarity correct (Thats my issue of course), am I right thinking that the 1000mA just means it *can* output up to 1000mA if required. So assuming the device uses less it wont hurt it.
