Before I played XBOX360, I was worried about the amount of voltage.  The amount of volt and watt of XBOX360 is 100 ~ 127V–3.7A, 47 ~ 63Hz Input AC 135W 12V 10.83A, 5Vsb 1A Output DC.  But the transformer is 750W input AC 220V output DC 110V.  so, it is okay to connect the xbox 360 adapter to that voltage transformer?

@justagamer24596 not if your transformer puts out “output DC 110V “! It should be AC voltage that your Xbox power supply plugs into. If it was AC voltage then yes, you can use is.

You are using a step down transformer, if you wish to plug more items into it, probably via a multi plug extension cord, you can add more items up to 750 watts, just don’t plug the toaster and the microwave in and use them at the same time LOL.
