    I have a ZEOS 400 that is missing the power supply. I’m looking at a universal replacement and wondering if you could advice me on the plug polarity and size of the plug.

      I know polarity is CENTER NEGATIVE off hand, so be careful with that, I think it’s 11.5volt, I will double check that and post back. No idea on barrel size, nor do I have anything on hand to accurately measure it.
