Ok so I have a question about the Nintendo transformer. If I put 120v in the output connectors will that hurt the transformer? I am thinking it will give me 120v and 100v on the other side? Is that correct? Or am I way off? Lol
 
An isolation transformer does not alter the voltage, it is what's called a 1:1 transformer. Putting 120v into it will definitely not hurt it, but unless it's a step down transformer, it's not going to decrease the voltage.

The Nintendo is a step down. 120 in 100 out. I don't know about hooking it up backwards I've never tried it.
