Heating temperature: (* The temperature of the hot and cold cup can be reached in about three minutes) About 58 ℃ -60 ℃, and the water temperature is significantly hot after 15-20 minutes. The specific heating effect is different from the temperature of the heating object and the thermal conductivity of the material

Refrigeration temperature: (* The temperature of the hot and cold cup can be reached in about three minutes) -3 ℃ -3 ℃, and the water temperature has a significant cooling effect in 15-20 minutes. The specific refrigeration effect is different from the temperature and material conductivity of the refrigeration object

Function operation: Press the cooling button to turn on the blue light, start cooling, and then press the shutdown button. Press the heating button to turn on the red light, start heating, and then press to turn off.
