Hello from Germany,
9V and 1500 mA should be okay as I have seen in some comments.
But a question regarding the polarity of the connector: in the middle + and on the outside ring –
Is this correct?
Yes correct. The jack should be 5.5/2.5 mm center positive.
However, 9V/500ma should be good enough. You don't need 1500mA.
