[0002] Keeping food and drinks fresh and at the right temperature is crucial during outdoor activities such as camping, hiking, fishing or long-distance driving. However, in an environment far away from power, traditional refrigerators cannot be used, and ice packs and coolants have limited effectiveness and gradually lose their effectiveness over time. Therefore, there is a strong demand in the market for a portable refrigeration device that can maintain a low temperature for a long time in an environment without electricity.

[0003] Existing portable refrigerators usually rely on the car cigarette lighter interface for power supply, which limits their use scenarios. Although some designs try to solve the power supply problem through built-in batteries or solar panels, when the battery is built-in and there is no charging power source nearby and the battery needs to be replaced to extend the cooling time, such a design requires disassembling the box to replace the battery, which is very inconvenient.

[0004] The utility model is made based on the above situation. Utility Model Content
