In today's tech-savvy world, it's become almost impossible to imagine life without smartphones and other electronic devices. But what happens when your phone battery is about to die, and you're nowhere near a power outlet? This is where a portable charger comes in handy. In this guide, we will show you how to make your very own portable charger from scratch. It's easier than you think! Let's get started.

Materials You Will Need

  • 1 small Altoids tin
  • 1 USB power bank module
  • 1 Lithium-ion rechargeable battery
  • 1 female USB connector
  • 1 male USB connector
  • 1 on/off switch
  • 1 small LED light
  • Soldering iron and solder
  • Wire strippers and cutters

Step 1: Prepare the Altoids Tin

Start by thoroughly cleaning the Altoids tin to remove any residues. Then, place the USB power bank module inside the tin and mark the spots where the USB connectors and switch will be placed.

Step 2: Solder the Components

Using your soldering iron, carefully solder the female USB connector to the USB power bank module. Then, solder one end of a wire to the switch and the other end to the positive terminal of the module. Next, solder a wire between the negative terminal of the module and the male USB connector. Finally, solder the LED light to the positive terminal of the module. Make sure all connections are secure.

Step 3: Insert the Battery

Place the Lithium-ion rechargeable battery into the tin, ensuring it sits snugly against the USB power bank module. Double-check that the polarity is correct before proceeding.

Step 4: Secure the Components

Using hot glue or adhesive, carefully secure all the components inside the Altoids tin. Make sure nothing is loose or touching, which could cause a short circuit.

Step 5: Test Your Portable Charger

Before sealing the Altoids tin, connect your charger to a device using a USB cable. Turn on the switch and see if the LED light turns on, indicating that it's working correctly. If everything is functioning as expected, proceed to the next step.

Step 6: Close and Label the Charger

Carefully close the Altoids tin and use adhesive or tape to secure it shut. You can also label it with a creative design or add information about the charger's capacity or output voltage for future reference.

In Conclusion

Building your own portable charger doesn't require advanced technical skills, and it's a great way to have an emergency power source on the go. By following these simple steps outlined above, you can enjoy the convenience of a portable charger whenever you need it. Charge your devices anytime, anywhere!
