Thermoelectric wine coolers are safe, but there are some hazards that you need to watch out for when using them.
One of the dangers of using thermoelectric wine coolers is that they can create hot spots. This means that certain parts of the cooler can get very hot, while other parts are still cool. If you touch the hot spot, you could get burned.
Another danger of using thermoelectric wine coolers is that they can create sparks. This means that there is a risk of fire if something flammable is near the cooler.
Be sure to read the instructions carefully and follow any safety precautions before using a thermoelectric wine cooler.
