A solar power bank is a portable energy storage device that utilizes solar panels to convert sunlight into electrical energy. As the demand for sustainable energy solutions increases, solar power banks provide an eco-friendly alternative to conventional power banks. This research explores the efficiency, feasibility, and limitations of solar power banks, analyzing their practical applications in outdoor activities, emergency backup power, and regions with limited access to electricity. Through careful observation, this research examines the components, working mechanisms, and energy conversion process of a solar power bank, assessing the effectiveness of solar panels, battery technology, and power management modules. Additionally, an experimental analysis was conducted to observe charging efficiency, battery storage performance, and adaptability under varying environmental conditions. Observations indicate that while solar power banks function efficiently under direct sunlight, their charging capability is significantly reduced in cloudy or indoor conditions, making them dependent on hybrid charging solutions. The research highlights key challenges such as long charging duration, energy losses in voltage conversion, and limited battery capacity. Future research could focus on integrating high-efficiency monocrystalline solar cells, AI-driven charge controllers, and graphene-based batteries to improve performance. The adoption of Maximum Power Point Tracking (MPPT) technology, hybrid charging options (solar + wired fast charging), and IoT-based energy monitoring can further enhance their usability. Despite current limitations, solar power banks have the potential to become a sustainable, reliable, and widely adopted energy solution for consumers seeking off-grid power alternatives.
