The beverage cooler and warmer is operated by a reversible thermo-electric heat pump, which is automatically regulated by an internal temperature regulator. The internal CPU regulates temperature by comparing the thermistor sensor value with 5 temperature values stored in memory. The device is able to hold cans, bottles up to 500ml, which includes most standard soft drink cans and small wine bottles. By confining the energy source in s small space, the cooling and heating process is mush faster than most mini fridges. And thus it is suitable for maintaining a constant temperature. For example, it can be used to keep the temperature of a bottle of white constant at the ideal temperature of 7°C(45°F) over the course of a long meal.

Features:
Three Functions In One Machine: cooler, warmer and constant temperature.
5 Temperature Settings: 3°C/7°C/12°C/21°C/50°C, good for different needs.
5 Colors LED Indicators: when the selected temperature is reached, the corresponding indicator will begin to blink.
Aluminum Cavity(75mm) Design: hold cans, bottles of up to 500ml, fitting for most standard soft cans and small wine bottles.
By confining the energy source in a small space, the cooling and heating process is much faster than most mini fridges.
Mini Size and Convenient Operation: suitable for household use, parties, in recreational vehicles, office and break room.
Wide Applications: keeping the temperature of wine constant; cooling beer or other beverage; heating milk for babies, even making yogurt, etc.
