    Hi,

    I need clarification with my understanding of transformers and amp
    requirements. I have a 12V DC fan that i need to cool a light
    fixture. The fan is 100mAmp max. The smallest AC to 12V DC
    transformer I can find is 300mAmp. Is it ok to use the 300mAmp
    transformer with the 100mAmp fan?
    Thanks
    Nate

    Yes; the fan will only use the amount of power that it needs.

    Definitely. The fan will draw only what it needs. That 300mA rating is the
    maximum amount of current you can draw from the transformer so you could
    actually hook up three of those fans to it.
