What is the cheapest way to supply power for anodizing?

Hi
Have not tried to anodize yet but would like to try. I have an automatic battery charger but I have read on the internet that you need to use a manual charger. If this is true what is the cheapest solution that will provide good anodizing results. I'm going to do this as a hobby not a production line so bear this in mind. Thanks.

You can use a 12V car battery. That's probably the cheapest option.

A rectifier is the best way to go if you plan on doing quite a bit of anodizing.
