Abstract
The increasing dependency on mobile devices has driven a need for sustainable and portable charging solutions. This project presents the design and implementation of a solar-powered power bank with multiple charging ports, providing an eco-friendly alternative to conventional battery chargers. The power bank harnesses solar energy through photovoltaic (PV) panels, converting sunlight into electrical energy stored in rechargeable batteries. The multiple ports allow simultaneous charging of multiple devices, enhancing the utility for users with various gadgets. The project explores key design considerations, including the selection of high-efficiency solar panels, the incorporation of a robust battery management system (BMS), and the optimization of charging circuits for different port configurations (e.g., USB, Type-C). It also addresses challenges such as energy conversion efficiency, power output stability, and adaptability to varying sunlight conditions. To improve performance, the system includes an intelligent control unit to manage power distribution and prevent overcharging, ensuring device safety. Additionally, the portability and versatility of the power bank make it suitable for outdoor activities and emergency situations where conventional power sources may not be available.
