Yesterday I bought a small hot pot to heat water for some hot beverages in the hotel room. It cost around US$9. I plugged it in, let it heat up the water and the area around the electric plug started smoking. I thought it might be just some new material that was not cleaned off when it was put in the box for sale so I tried it again. The second time it started smoking and smelling like some kind of plastic material burning. I looked more closely at it and it was the plastic bottom just above the electric outlet on the pot. The plastic was also starting to bubble which indicates it was getting way too hot.
I took it back to the shop and they pointed to the little sticker on the side of the pot that said that the electric connector to the pot has to be pulled out at a certain time or the pot will start smoking which is not a problem. But another problem was that the pot was making a popping sound as well which indicates that the plastic was burning. So I told him I didn’t want it because it was actually dangerous and after giving them another US$3 I got a more advanced hot pot which doesn’t smoke.
