Portable Mini Car Refrigerator/Warmer.

Dual Functionality: It can both cool items down to a certain temperature below ambient room temperature and warm them up (e.g., up to \(60^{\circ }\mathrm{C}\) \(\pm 5^{\circ }\mathrm{C}\)). Power Source: The unit typically operates using a vehicle's 12V cigarette lighter socket, but some models also work with standard indoor AC adapters (100-120V).
