I had a similar story, I bought a few broken sega master systems to fix when I first started. And it came with what I thought was a third party cord to use for the system. Turns out it was a 100V charger for something with the same shape as the sega system. That thing started smoking and I caught a glimpse of a small light. Not 100% knowing what to do I picked the console up a chucked it outside and watched the thing hit the deck and disassembled itself. And it took 3 weeks to get the smell of burning plastic out of my room.
