Solar Based Power Banks Supporting Affordable and Clean Energy

Today, we all use things like smartphones, smartwatches, and other small gadgets that need power. But sometimes, it's hard to find electricity, especially in villages or places far from cities. So, we need a way to charge our devices even without electricity.That's why we made a solar power bank. It's a small and easy to carry device that uses sunlight to make electricity. This electricity gets stored in a battery inside the power bank, and later we can use it to charge our phones or other devices.We used parts like A solar panel to collect sunlight A TP4056 module to safely charge the battery USB ports to connect phones And some safety parts to protect the batteryThis power bank is good for the environment because it uses sunlight instead of electricity from the grid. It also helps people who don't always have power at home.Our project supports two big global goals Clean Energy SDG 7 – so everyone can have safe and modern energy Climate Action SDG 13 – so we can fight pollution and protect the EarthWe built the power bank, tested it, and it worked We learned a lot about how solar energy works. It shows how we can use the sun to power our everyday devices. This is a small step to help the planet and use clean energy in the future. Devesh Roy | Jigyasa Jaiswal | Dr. Srilatha.
