Hi, Paul. The eliminator I have goes up to 6 AA batteries (they have 2 and 4 cell versions, too), so any device that takes up to 6 AA cells can be powered off this particular unit. They have something for 9 volt batteries, too, but there are better ones sold by Radio Shack and other electronics stores. The one from QCAvionix plugs into a lighter socket, and I had to get a converter to get it working on house current. The one RS and other stores sells works on house current directly. As for AAA, C, D, and so on, I haven't seen anything that serves an equivalent function, though I don't see why such a thing couldn't be made. HTH.

How cool is that! What the thing you are using needs more than two batteries or batteries of a different size like c or d?
