Abstract The increasing demand for compact, mobile, and efficient electronic devices has led to significant advancements in portable power solutions. Portable mobile charging systems, commonly referred to as power banks, have become essential, particularly for individuals in regions with unreliable electricity supply. This project focuses on the development of a portable solar-powered mobile charging system designed to meet the growing needs of mobile device users. The proposed system is equipped with a 11,400mAH battery, capable of charging mobile phones and laptops, and is designed for easy transport and efficient charging. By utilizing a combination of solar energy and conventional charging methods, the system offers an environmentally friendly, cost-effective solution for users in both urban and remote areas. Key features of the system include multiple charging ports with varying power outputs, smart decision-making algorithms for optimal energy management, and a compact, lightweight design. This project aims to provide a solution to the limitations of traditional charging methods, offering enhanced convenience, efficiency, and accessibility, while ensuring compatibility with a wide range of devices. The system's effectiveness will be evaluated through rigorous testing to verify its reliability, speed, and energy efficiency.
