520			_aThis study focuses on the development of a portable thermoelectric cooler and heater system, designed to provide an efficient solution for maintaining optimal temperatures in various environments. The system utilizes thermoelectric coolers (TECs) to regulate the temperature inside a 5-liter insulated container, allowing it to cool or heat items based on user-defined settings. Unlike conventional cooling and heating devices, the system operates on DC power from a vehicle's power supply, making it suitable for off-grid and portable applications without reliance on refrigerants or external electricity sources. A temperature sensor continuously monitors the internal temperature, while a fan ensures even air distribution to improve efficiency. The system was fabricated using locally available materials, keeping costs low while maintaining durability. Testing was conducted to evaluate the cooling and heating efficiency of the system under real-world conditions. The results showed that the chiller successfully lowered the internal temperature from 25°C to 13°C within a specific time frame, demonstrating its effectiveness in cooling beverages. The heating function utilized waste heat from the TEC module, efficiently maintaining temperatures suitable for warming food or drinks. Performance experiments based on workability, effectiveness, aesthetic safety, economy, durability, and cost- effectiveness. showed that the system met most of this study's objectives. Economics scored lowest 4.36 and aesthetics highest 4.87 in our overall evaluation, which yielded an average score of 4.65 out of 5. Keywords: cooling, heating, portable, sensor, temperature.
