Why would it? The transformator pretty much dictates the maximal power.<br>

I can understand the logic of that statement. However, once I verified
that the output without load (any load will negate the resistor
anyways) is the same as the reference power supply I'm trying to
mimick, wouldn't that mean that I'm okay with things as they are?<br>

I guess so.<br>
since you device can handle higher voltages anyway, I do not see any
problem.<br>
<br>
one more thing you can do, is to open up the 110V transformer and see
what inside, my guess is that it have no other component then the real
transformer inside, with pa primary coil for 110v and secondary for 12V.<br>
and you replace it with another one when the primary coil is 220V.<br>
BTW, how heavy it is?<br>
