ABSTRACT:

 This mini-project addresses the growing demand for accessible and durable mobile charging solutions in public spaces by developing a novel plastic-based mobile charging station. The ubiquitous use of smart phones and other portable electronic devices highlights the critical need for reliable charging infrastructure outside of private settings. Current commercial public charging stations often rely on heavy, expensive metal enclosures, which are prone to corrosion and increase manufacturing complexity, presenting a barrier to widespread, cost-effective deployment.

The core innovation of this project lies in utilizing engineering plastics such as high-impact ABS or fire-retardant polycarbonate for the structural housing and key components of the charging station. This material shift was driven by the objectives of significantly reducing the Bill of Materials (BOM) cost and overall weight while ensuring comparable durability and weather resistance. The design focused on creating a modular, aesthetically pleasing, and tamper-resistant enclosure that can be easily mass-produced using common plastic fabrication methods like injection molding the station was engineered with a focus on sustainability and circular economy principles. The selected plastic materials are readily recyclable, minimizing the environmental impact at the product's end-of-life cycle. This approach not only provides a cheaper solution but also promotes an environmentally conscious infrastructure choice for municipalities and facility managers.

A critical phase of the project involved rigorous testing to validate both the mechanical and electrical performance. The plastic housing underwent tests for impact resistance, UV degradation, and water ingress (IP rating) to guarantee reliable operation in varied outdoor and indoor public environments, thermal management, and compliance with international safety standards, confirming that the plastic enclosure does not compromise the electrical integrity or user safety.

In conclusion, the development of this plastic-based mobile charger offers a lightweight, cost-effective, and scalable alternative to conventional metal designs. This innovation makes public charging infrastructure more economically viable for wide-scale implementation,   thereby enhancing user convenience and supporting the continuous operation of mobile devices in shared public environments.
