Construction of Portable Chargers Using Components from Electronic Cigarettes

Objective: This study proposes a practical and sustainable process to transform disposable electronic cigarettes into functional portable chargers. The initiative aims to reduce the improper disposal of these devices by reusing viable lithium-ion batteries, offering an ecological and low-cost alternative for electronic waste reuse. Method: An exploratory approach was adopted, including a literature review and a case study. Disposable e-cigarettes were collected and disassembled to evaluate the feasibility of battery reuse. The analysis followed the GQM (Goal-Question-Metric) method, considering efficiency, safety, and sustainability criteria. Results and Discussion: Approximately 90% of the batteries were suitable for reuse. The developed prototype provided a stable 5V output with short-circuit protection. Waste was properly sorted and disposed of, reinforcing environmental responsibility. Research Implications: This study contributes practical solutions in the fields of sustainability and environmental education, highlighting the reuse of electronic components as a viable alternative to improper disposal. Originality/Value: The project is innovative in applying technological reuse to disposable e-cigarettes, generating functional, sustainable, and low-cost products.
