Multiport universal solar power bank

Abstract. In an era of ubiquitous electricity dependence, the need for a reliable and portable power source is increasingly vital. This proposal advocates for the development of a solar-powered portable device capable of harnessing solar energy to charge itself and subsequently supply power to various electronic devices. The envisioned solution aims to address critical scenarios such as emergencies, where access to electricity is crucial, as well as recreational activities like camping, especially in remote locations. The proposed portable power bank will be equipped with solar panels for efficient energy absorption, ensuring self-sufficiency and sustainability. The device will feature both DC and AC outputs, catering to a wide range of electronic gadgets, thereby enhancing its versatility. In the event of a disaster, this innovation could prove invaluable by providing a reliable source of electricity when traditional power infrastructure is compromised. Moreover, in recreational settings, such as desert camping in locations like Saudi Arabia, users can harness the power of the sun to charge their devices in the open, offering convenience and environmental friendliness. This solar-powered portable energy hub embodies a step towards fostering energy independence and resilience in the face of unpredictable circumstances, catering to both emergency preparedness and everyday scenarios.
