Yes you use with an AC outlet that you plug into is when you can use it.

This is an AC to DC power supply so it does the conversion for you.

Best and cheapest place is to buy it from Victor_inox here on the forum. PM him for details and pricing. I recommend getting the mounting feet for it as well for it's well worth it.
