What is a Power Bank?
A portable rechargeable battery that allows you to connect to an external charging source when you don’t have access to a wall charger is known as a power bank.
The demand for power banks has exploded, resulting in one of the most prominent electronic products available. However, such a fantastic device comes with an equally unbelievable price tag.
Fortunately, in this article, we will take you through the step-by-step approach to creating your rechargeable power bank.
It will be pushing 1000mAH with the use of a 4V DC battery.
The typical market-generated power bank can be broken down into three primary components. A rechargeable Lithium-Ion (Li-ion) or Lithium Polymer(LIPO) battery, a battery charger module (typically based on the TP4056 IC), and a DC to DC converter module are all required. To attach the power bank to an exterior tool, you’ll also require a Micro USB cable.
How Does a Power Bank Work
A power bank must be charged to store energy to, in turn, charge devices that are connected to it. To charge the power bank with a wall outlet, first, use the adapter cable that came with it.
The power bank can be utilized for charging electronic devices once you see the indicator light on it come on, which indicates that the accessory is fully charged.
The energy stored in a power bank is transmitted to the device via a charging wire from a USB port.
How to Make a Portable Power Bank
Now that we’ve looked at power banks and how they can be costly, let’s look at how you can easily make one or a few at home. First, you’ll need to obtain all the necessary components.
Hardware Components
You will require the following components to create your portable power bank.
- A smartphone
- Scissors
- Wires for connection
- One 4V/Lead Acid DC Battery
- One 3.7V/5V DC converter module charger circuit board
- A USB to mini b/2A micro USB charging cord
- A two-sided tape
- A 45-60 Watt soldering iron
- Wire and Flux for soldering
Steps For Making A Power Bank
1) Take the scissors and use them to cut a piece of double-sided tape and make sure to stick it to the battery’s surface. Once you’ve done that, fasten the battery charger module to the next side of the tape.
2) Next, solder the battery’s +ve and -ve terminals to the charger board circuit’s terminals. Make sure to pay attention to the sequence of the terminals. This is critical for the project to work.
3) It’s now time to test the charger board module. This is done by using the test switch.
4) Charge your smartphone with a micro USB cable.
5) Once the battery is drained, charge it with a 5V/2A charger.
How it Works
This circuit’s operation is straightforward. The 4V battery provides a DC power pool because the battery provides a standard of 3.7V DC.
What the charge controller module does is make sure that the battery is adequately charged while also protecting it from overcharging.
The charger circuit board’s inbuilt DC to DC converter module produces a reliable output of 5V/2A.
The charge control circuit board has the Surface Mounted Device LED situated on top of it to indicate what the charging status is when the circuit is linked to any exterior output tool or in a wall plug to be charged.
Applications
They’re commonly used to charge electronics like smartphones, game controllers, and lamps, among other things.
Power Bank Lifetime
A power bank’s usual working life is between 200 and 1000 cycles. A cycle is defined as one charge and one use of a device, either wholly or partly charged. After a certain number of charging cycles, the typical lithium-ion battery in a power bank will lose capacity. Because bigger power banks compel fewer charging cycles than their smaller counterparts, they will last longer.
Although there is no assurance as to the length of time that your power bank will endure, lowering how frequently you utilize it can help it last longer.
Final Thoughts
Now that you know how to make your power bank and how simple the process is, we hope that you’ll proudly use and show off your newly acquired skill.
