In this tutorial, we are developing a project of a “50,000mAh power bank” from scrap. Power banks are common because of the expanding utilization of “battery-powered hardware”. Everything from cell phones to the “wireless earphones”, “speakers”, “MP3 players”, etc. can be charged utilizing a power bank. They are viably a versatile charger. All they need is a “USB charging interface”. There are different types of power banks in terms of sizes and shapes.

Nowadays, people use power banks more significantly as they provide the easiest and very simple method of charging “smartphones”, “MP3 players” and other devices when you are away from your “home” or “main power source”. “Wireless power banks” have additionally been introduced for those devices that can be “charged wirelessly”.

Hardware Components

The required hardware components for making a 50,000 mAh power bank from scrap are listed below:

CIrcuit Construction

Step# 01

Buy a power bank from the local market.

Step# 02

Disassembled the power bank and take out all the cells and destroy them.

Step# 03

Take an old laptop battery.

Step# 04

Take out all the cells from the laptop battery.

Step# 05

Join 3 connected batteries and 2 connected batteries together through the wire and remove the resistor.

Step# 06

Join the wire at another end of cells.

Step# 07

Join USB port circuit with the cells

Step# 08

Connect the cells from the circuit through the wire.

Step# 09

Connect the circuit from the cells from another point.

Step# 10

Now the 50,000mAh Power bank is ready.

Step# 11

Then cover the Power bank from Power bank cover and your Power bank is ready.

Circuit Operation

The circuit of the “50,000mAh Power Bank” is not so difficult to make. Only you need an old laptop battery, a local power bank and some wires. We take out all the cells from a local power bank and replace it with the cells of laptop battery. The “cells of a laptop battery” have much higher capacity than the “local power bank”. As a result, you will get an efficient and high-quality power bank. This power bank has the capacity of 50,000mAh. 

Applications and Uses

The power bank is used to charge

  • Smartphones
  • MP3 Players and other devices etc.
