Abstract	The rapid growth in mobile phone usage has significantly increased the demand for reliable and portable charging solutions. Conventional chargers depend on grid electricity, which is not always available in remote areas or during outdoor activities. This paper presents the design and development of a portable solar-powered mobile charger that utilizes photovoltaic (PV) technology for sustainable energy harvesting. The system integrates a solar panel, lithium-ion battery, TP4056 charging module, voltage regulator, and boost converter to provide stable 5V output suitable for mobile charging. Experimental validation was conducted under real sunlight conditions to evaluate charging performance. The proposed system demonstrates an eco-friendly, cost-effective, and practical solution for small-scale renewable energy applications.
