look on the front of the plug.it will say input 120v,output ~v.mine are 12V output,so I got a 12v transformer.
 
If you have 2 12v 200ma then you need at least 12v 400ma power supply. You can get about any size you want at radio shack.

If you needed 400ma and you had a 900ma wall wort, would it be a problem? As in too much?
