★ Instructions for use: This refrigerator belongs to a semiconductor refrigeration refrigerator, and the refrigeration temperature can generally be lower than room temperature by about 20 degrees. If your indoor temperature is 30 degrees, the minimum refrigerator is 10 degrees. The minimum temperature in winter is about 0 degrees, and the minimum in other seasons is about 3 degrees, depending on the ambient temperature. This refrigerator has no freezing function. The heating can be adjusted to 65°C. When it reaches or exceeds the set temperature, the refrigerator stops working for heat preservation, and the heating is not affected by the external ambient temperature. Specification: Product name: Mini refrigerator Rated power: 75W Rated voltage: 12V for car; 220V/110V for home Cooling temperature: Dual core: 25°C (lower than current ambient temperature) Heating temperature: can be heated to 65°C (not affected by ambient temperature) External dimensions: 28.5*35.5*42CM Internal size: 22*23*34.5CM Capacity: 22L (drink 300MLX28; mineral water 550MLX15 bottle) Power cord length: car cable 1.8 meters; household cable 1.5 meters Note: The low power of the small refrigerator cannot be frozen, and the cooling is related to the ambient temperature. The higher the ambient temperature, the longer the cooling time.
