Haha so controversial :-p I did not say it was a good idea, just a neat trick. I actually _had_ to do this once, when I forgot a 220v to 110v adapter for a wireless microphone, for a wedding, in an hard to access location [1], and there was just no time to go get a transformer from anywhere else :-) Luckily, the whole "setup" did not turn into fire for the 30 minutes or so that the mic was needed and the wedding speech could actually happen without anyone needing to scream :-) 1: https://en.wikipedia.org/wiki/Tigre,_Buenos_Aires https://en.wikipedia.org/wiki/Tigre,_Buenos_Aires
