Introduction: How to Make a Mobile Charger

About: Hello Guys, I am techgenie, an Electronics hobbyists, tech tinker and developer. I dedicate my free time in designing and making various creative and innovative projects, RC toys, Incredible Gadgets, Awesome...

Don't have a mobile phone charger and the battery is about to drain..?

Make an Emergency Charger yourself at home to charge your device from nothing but a 9v Battery.

This video shows a simple way to learn how to make a mobile phone charger at home very easily.

Note: A normal zinc carbon battery will not give much backup and will get drained out fast. So, its recommended to use rechargeable batteries.

Step 1: Components Required

  1. General Purpose PCB Board - http://amzn.to/2lkylJH
  2. LM 7805 Voltage Regulator - http://amzn.to/2lYjysF
  3. 100 uF capacitor - http://amzn.to/2nlsokr
  4. 10uF capacitor - http://amzn.to/2lYocGK
  5. Female USB Port - http://amzn.to/2mq9jtg
  6. 9v Battery - http://amzn.to/2nlmK1I
  7. Battery connector clip - http://amzn.to/2mH5Rey

Step 2: Procedure

1. Refer to the circuit diagram of the project.

2. Insert the clip on PCB board and paste it using hot glue.

3. Solder the connector to the base.

4. Solder a 100uF capacitor parallel to the connector clip.

5. Refer to the pin configuration of 7805. Solder the IC on the base such that, input pin is near the capacitor and connect input pin to +ve terminal of capacitor.

6. Take a 10uF capacitor and solder the +ve terminal to the output of 7805 I.C.

7. Refer to the pin configuration of female USB port. We have 4 pins

  • pin 1 - Vcc
  • Pin 2 - Data (-)
  • Pin 3 - Data (+)
  • Pin 4 - Ground

8. Solder the port to the base and connect pin 1 to the +ve terminal of 10uF capacitor.

9. Make all the ground connections.

Step 3: Mobile Charger Is Ready

Our Mobile Charger is now ready.

Note: Use it only in case of emergency, for regular charge, use normal wall charger.

Attach a 9v Battery and connect the mobile phone using a USB cable, we see that, the mobile charges well.

    Yes, you can but then you also need to use a heat sink with 7805 voltage regulator because it will get hot and can burn out.

    No, a mobile adapter works with 220v AC power supply.

    Don't do with regulators like 7805 try other regulators, as in this 7805 burns more energy in bringing 9v to 5v in form of heat and battery is also expensive. Joule's thief is also nice concept you should think about it.

    but neat and clean work nice keep it up :)

    Thank you for appreciating my work..:) Yes, 7805 do get heated up and loses more energy but it is very commonly available and moreover this is only an emergency charger..:-p

    Thanks for suggesting about Joule's thief, will look into it soon. Can you suggest me some nice joule's thief projects or some verified links..?

    The Joule thief circuit isn't overly efficient, what it gets you is it lets you discharge batteries far further. For example, your circuit will stop working after a 9V battery's voltage sags much past 7V, which tends to leave a lot of power in the battery. The Joule thief will drain the battery down to ~1V, using up all power you could reasonably extract from any given battery.

    However, the big downside to Joule thief circuits, is they will destroy rechargable batteries, because the battery will be discharged far past it's minimum voltage; not many rechargable batteries can handle more than a couple deep discharge cycles, and Lithium batteries in particular can detonate when recharged after being over-depleted.

    9V batteries have terrible properties for this circuit, even with a rechargable model, you'll probably only extract maybe 100mAh from the battery before the voltage drops below what the 7805 can regulate. That's barely enough to turn on the "charging" indicator light for more than a few minutes, and wouldn't even charge more than 2% of my cell phone's battery; nowhere near enough to place a call, and barely enough to send more than a handful of SMS messages.

    A better choice would be 5x or 6x AA or AAA batteries; not only are
    those sizes more common and cheaper, but they store FAR more energy, and
    if you use 5x batteries, then the 7805 will waste less power as heat.
