How to Make A Phone Charger with AA Batteries – AA Battery and Working

Rechargeable batteries are quite effective until they run out of juice. At that moment, you will need a good charger and a source of power. But what if you don’t have any of these and you cannot even access them?

You can make your own portable charger and enjoy good power instead of spending too much money to buy one. Well, you will eventually have to invest in one, but for now, you need an emergency option. Most people have never thought about this because there are so many chargers out there. Also, there is a lot of information on how to make a portable charger. Some of which may be quite confusing. Keep reading this guide for the most simplified version.

How to Make a Phone Charger with AA Batteries

This project is probably for those who like trying out some new ideas. It’s all about wanting to do something you have never done before, even if there is no real charging emergency – although it would make much sense if there were.

It is very simple to make this charger, and anyone can do it from their home. The charger operates by reducing the voltage of four 1.5V AA batteries via a voltage regulator. The voltage required by a phone for charging is 5V, and that is why the regulator is an essential piece of this process.

The first requirement is to have that zeal and motivation to do something unique. Even if you have never worked with electronic devices in such a matter, being able to follow instructions can get you anywhere you want to be.

In this guide, we will share three crucial steps you can easily follow to make a portable charger safely. Most of the materials we will use are cheap and readily available. So, don’t worry about spending too much.

Step 1: Gather Your Materials

You will need the following tools for this project:

A battery holder for four 1.5 AA batteries. You can make your own, or buy a cheap one on the internet.

Four 1.5v AA batteries. These are readily available in your local retail store or supermarket.

A voltage regular IC 7805. You constant output voltage, and this is the device that will give you that no matter the output.

A USB A-male to Micro B cable. You will need the micro end for connecting your phone to the portable charger.

Glue gun.

Step 2: Connecting

First, you need to understand how the charger will be working. In this case, when the AA batteries are connected in series, they give a total voltage of 6V, which is over the limit of your phone. It cannot, therefore, be connected directly for charging, which is why we need the IC 7805 – to regulate the voltage and give a constant 5V output.

Follow these steps to make your charger:

Step 1: Cut the micro end of the USB and remove the data cables. We only need the red and black wires.

Step 2: Use a soldering iron to paste the regular on the battery holder. Use the glue gun to secure it on the surface effectively.

Step 3: Insert the four AA batteries into the holder, and make sure they are fully charged.

Step 4: Your charger is not ready for use. You can try it out at this point.

Step 3: Using the Charger

As you can see, making the emergency charger is not very hard. As long you have all the materials ready, it should take you the shortest time to get the job done.

How to Make a Portable Charger Easy

Can you make a portable charger? Yes, and it’s very simple. Unfortunately, there is too much conflicting information about it. In this guide, we are going to make it simple in three easy steps.

You will need:

A small container

A phone car charger

Two gator clips?

or cables

A 9V battery and snap connector

An electrical tape

Scissors

Metal cutters/ snips

Step 1: How it Works

With the materials ready, you can now start wiring. Take the gator clips and connect one end to the positive wire on your snap connect. Take the other end of the gator clips and connect it to the metal contact of the car charger.

Connect one end of the second gator to the negative wire of the snap connector and the other end to the metal contact of the car phone charger. Once that is done, you can now wrap both connectors in the electrical tape to keep the circuit safe.

Step 2: Trimming

Your charger is almost done. All you need to do now is connect the 9V battery to the snap connector and put the wiring in your connector. Mark on the outside of the container where you will connect the USB, and then use metal cutters to create the space for it.

Step 3: Wrapping it Up

Put the wiring, the battery, and the charger into the container. Once don’t, you can connect your phone using the connected USB cable and see if it charges. Congratulations! You have made a portable charger.

How to Make a Charger Work

You can fix a broken charger by first understanding the problem. Some fixes may require some wiring, while others only need a simple touch, and it will be working again. Here are some ideas for making your charger work:

Check the outlet and ensure it’s turned on. Whether it is a homemade charger or the one you bought, the first point should be to check the connection to the outlet.

Ensure the cables are connected well. Try unplugging all the cables in the system and then connect them again.

Check for the status lights.

Reboot the device you are charging. Sometimes it might not even be the charger but the device.

Try another outlet if the one you are using does not seem to work well.

Check if there are any damages on the charger and fix them. Issues like bare wires and stripped insulation can cause problems.

Check the components

Clean the charging ports

Try different cables and power adaptors.

If you have tried everything and the charger still does work, it could be time to buy a new one.?There is nothing much you can do about a broken phone charger.
