In the summer, we always want to drink an iced Coke at any time, and then the Coke will soon go out of ice in the car. A large car refrigerator is not only bulky but also wastes electricity. This refrigerating cup holder solves this problem very well.
It's so small that it fits in a 's cup holder and works from the car's 12V power supply. In addition to having a cooling version, we also have a cooling + heating version.
