A while back I picked up a second hand step up/down transformer to use 240V devices in the US. But it was more than I bargained for to make it safe to use.
So not buy one of these. I will not be recommending any of them here, every single listing online for any model or brand that I could find with a significant number of reviews has some that talk about short, melting, and fires. All the things that would happen if the issues I found here were left unresolved.
I may continue to use it, but I am going to be putting in over current protection to limit it to 1/4 of it's rated power. I would never leave this unattended and will never think of it as safe because there is the potential for the transformer to have quality issues as well.
