Data is Beautiful

Velas: perhaps it's a regional thing, but here in Curitiba I hear it all the time, for both volts and watts. e.g. last week someone asking me if the RGB in my computer was "de doze ou cinco vela" (12V or 5V). Or someone else saying a LED lamp was equivalent to an incandescent lamp of "oitenta velas" (80W).

220V is plain better, as in the video OP linked, you aren't losing much from it. Odds are hotels in your city only have 127V for appliances guests might bring with them. (Here in Paraná it's just two cities like this. Everyone else is in the same mess as Curitiba.)

Yep, my dad can’t stand the ground pin in almost every plug. I had to convince him not to destroy them all.

My sister, too. She was in a position to know it better, but... *shrugs*
