How to make rechargeable power bank at home -latest tips & tricks
Powerbank is an electronic device with lithium batteries that are charged "
The demand of power bank has become very high in today's time, because most people use internet in their smart phones and it also drastically reduces the battery of the phone so that the mobile is not able to run properly even for half a day and then when In the metro, charging socket is not available everywhere in the office when it comes to charging mobile, that's why people keep power bank with them so that they can charge mobile in emergency. Power bank is such an electronic device that has lithium batteries which are charged and then later they charge their mobile. So today we are talking here how to make rechargeable power bank in Hindi. If the article looks good then please comment.
Step required to make power bank
Many people search on the internet about the power bank and they get different types of circuits which cause them to become quite confused and if you use local circuit design in your circuit then soon either power bank The battery will be damaged or your mobile may be defective, as lithium battery is used in the power bank, which is very important to maintain both protection and quality.
So I am not giving you any local circuit, I am giving you reference circuit design which module you can either design yourself or buy directly from the market or online.
Required components to make power bank:
1. Lithium cell 18650
2.TP4056 Module
3. 3V to 5V converter board(1 Amp.)
1-Lithium cell 18650:
The lithium battery cell is shaped like a cylinder and the special thing is that it keeps the output voltage and current constant. These cells can be charged again like a battery and their capacity to store power is also very high, whose output is typically 3.7 volt.
2-TP4056 Module:
This reference module is a very good circuit to charge any single Li-on battery and this circuit is used in most power bank industries. This circuit has two LEDs, the blue LED burns when the charging is complete and the red LED burns in the charging operation.
Specifications:-
Specifications:-
- Charging mode:linear charge
- Charging current:1 amp
- Charging voltage-4.5-5.5v
- Full charge voltage-4.2v
3V to 5V boost converter:
As we have already said that we get 3.7 volts from lithium batteries but we need up to 5 volts to charge the mobile phone battery, so we need this circuit to make 3 volts to 5 volts. . There is also a RED color LED in it whenever it is powered on by the battery, it becomes LED ON.

Connections :

According to the connection diagram you have to design the circuit which is very simple. Now to mount these two modules in a box properly, you can use glue to mount so that the module sticks well and does not shorten. If you want, you can also use a switch between the module, the battery and the converter, so that when you charge the power bank, turn the charger switch ON and when the mobile charge, switch to another. The usb of TP4056 Module has to be connected to the charging unit (charger adopter) and the mobile to the usb of 5 volt converter.
