Can a KitchenAid mixer travel from US to Europe?
I burned out a food processor, a wand mixer, a stereo, and a fan, all using 220V–>110V transformers that were rated at or above what they were supposed to be. Anything with a motor in it is a massive gamble, especially anything that encounters any kind of physical resistance and strains a bit (i.e. my poor food processor that began emitting smoke from its underside before it simply stopped working forever). We had friends who used a shoebox-sized transformer to operate their North American blender, but the transformer was a gift from someone who evidently used it to test out aviation parts. Good luck finding something similar. If I were you, I’d get the machine fixed/replaced and sell it on eBay.
