When it comes to voltage adaptors, you have to use the same ratings that's on the console or higher. Case in point: I needed an adaptor for my Sega MS. The voltage was like 800Mv or something. It's an unheard of rating now, so I had to get a Genesis one, which is somewhere near 900Mv. You just can't go lower on the voltage or it will mess up the console. But higher is okay.
So the one on the Top Loader can be used on the CDZ, but not the other way around.
