    Gidday guys

    I have a battery powered pencil sharpener (4x AA) which I'd like to hook up to a power pack instead.

    I'm guessing 6v, but what milliamps would do the trick?

    Thanks for your time and help.

    Hello and welcome to Electronics Point :)

    1A (one amp) should be plenty. You might get away with 500 mA (1/2 amp) but there wouldn't be much cost difference, so I would go for a 1A adapter.
