How To Make a mobile Power Bank At Home

In this article, we will discuss how To make a mobile power bank at home. You should have some basic knowledge of electronics For example, what is DC and AC? electronic circuits and systems.

Voltage is measured in volts, and is represented by the symbol V. The voltage at any point in a circuit is determined by the sum of the voltages of all the components in the circuit.

Voltage can be generated by a number of sources, including batteries, power supplies, and solar panels.

What is the difference between DC volt and ac volt?

According to Wikipedia in electrical engineering, a direct current (DC) converter is an electronic circuit or electromechanical device that converts a direct current (DC) source from one voltage level to another.

There are two types of voltage: direct current (DC) and alternating current (AC). DC voltage flows in one direction, while AC voltage alternates between positive and negative voltages.

The type of voltage you use depends on the application. For example, if you’re powering a DC motor, you would use a DC voltage. If you’re powering an AC motor, you would use an AC voltage.

3.7v Li-ion Battery

Li-ion Battery

Li-ion batteries are a popular type of rechargeable battery that uses lithium ions to transfer energy.

They come in a variety of shapes and sizes, but all have one thing in common: they hold a charge much longer than traditional batteries.

This means they can be used for a wider range of applications, from powering small electronics

Switch Slide

Switch Slide

Switch slide is a simple ON and OFF button, Which helps your device to start and stop the function.

Soldering Iron

Soldering Iron

A solder is a metal alloy that is melted and used to join two metals together.

A soldering iron is a tool that is used to heat the solder and make it flow between the two metals.

The soldering iron is heated up by electricity and then the solder is melted and put on the joint where the two metals are to be joined.

When the solder cools, it forms a bond between the two metals.

Hot Glue Gun

Glue Gun

A hot glue gun is a device that uses a thermoplastic adhesive called “hot melt glue” or “hot glue” to bond objects together.

A small amount of molten adhesive is extruded from the nozzle of the gun, which is then quickly cooled to form a solid bond.

TP4056 Charging Module (Lithium Battery Charger)

TP4056 Charging Module

This device is used to charge your power bank.

The TP4056 Charging Module is a small and efficient device that is used to charge Li-ion or LiPo batteries.

It has a USB input and can charge batteries at a rate of up to 1A.

The module also features protection against overcharging, short circuits, and reverse polarity.

Solder Tabs

Solder Tabs

Solder tabs are small metal tabs that are used to hold a component in place while you solder it to a circuit board.

They come in a variety of shapes and sizes, but all do the same job; keeping the component in place so you can solder it without worrying about it moving around.

3.7v to 5v Boost Converter

3.7v to 5v Boost Converter device

A boost converter is a DC to DC converter that steps up (or boosts) the voltage of a power source.

It does this by taking in low voltage and outputting high voltage.

This is a very handy tool to have when you need to step up voltage for a project or device.

Circuit Diagram to better understand for you

Circuit Diagram


Only Android devices may be charged with this PowerBank. D+ = 2.76v and D- = 2.06v for 1A current draw, and 2.0v and D—>2.0v for 500mA.

The current draw requires a particular voltage at the data pins that may be easily created using a voltage divider circuit with a few resistors to charge an IOS device.

However, I didn’t give much thought to providing voltage at data pins because I needed it for android devices.
