The Power Bank Pen is a multifunctional device designed to support students during power outages and daily learning activities. It combines a writing pen, touch-activated LED light, and mini power bank in one compact structure. Using a rechargeable 3.7V lithium-ion battery, charging module, USB output, and touch sensor, the device provides writing capability, emergency lighting, and basic mobile charging. The development involved design planning, component integration, and functional testing to ensure safety and usability. Compared to conventional tools, it improves portability, convenience, and cost efficiency while promoting sustainable energy use aligned with SDG 7 and SDG 11.
