I could not find any similar issues, but i bought a Xiaomi power plug with power measurement for my washing machine, and for people from the EU a converter is delivered with the plug.
The xiaomi plug should be able to handle 2500w, but apparently the converter doesn’t. It just melted down, i was lucky that i smelled the burning plastic so i was in time to shut it down.
This hasn’t even to do with Xiaomi. Once I plugged a toaster into a converter socket and while I was making break, the whole converter thingy got up in smoke and melted.
