Abstract : The FLEXIBOX is an innovative, portable food storage solution designed to maintain optimal food temperatures, keeping meals warm or cold on the go. Utilizing the power of Peltier thermoelectric modules, the box integrates both heating and cooling functionalities in a compact, energy-efficient design. The system allows users to easily switch between heating and cooling modes, ensuring that food is maintained at the desired temperature for hours, whether it’s a hot lunch or a chilled snack. This project aims to enhance convenience for busy individuals, providing a smart, eco- friendly solution to meal temperature management. The FLEXIBOX is ideal for students, office workers, and travellers, offering a seamless blend of technology and practicality to address the challenges of meal transportation and preservation
