Описание: 🔋 Description: How to Make a Power Bank at Home
In this video, we will show you how to make a homemade power bank using simple electronic components. This DIY power bank is easy to build and can charge your mobile phone or other USB devices anywhere. We will use 18650 lithium-ion batteries, a power bank module (TP4056 or 5V boost converter), and a few wires to assemble it.
You’ll learn step-by-step how to:
Connect the batteries safely in parallel or series.
Attach the charging and output module.
Check voltage output and test with a mobile phone.
This project is perfect for students, science lovers, and DIY creators. It’s a great way to recycle old laptop batteries and make a useful gadget at home.
👉 Disclaimer: Do this experiment carefully and only under adult supervision, as lithium batteries can be dangerous if handled incorrectly.
