Make an Emergency Phone Charger – MacGyver Style!

Solar & Wind EBooks



In this video, you’ll learn how to “MacGyver” a 40 Watt Electrical Generator from a cordless drill and a few household items. Here’s how to charge your phone, illuminate small lights, and make electricity in a pinch.

Project Inspired By:

Kipkay’s video charging a phone with a crank flashlight http://youtu.be/Z_JI2Rvdzqs

WARNING:

This project is intended to be a “bare bones” approach to generating electricity in a tight situation. There are no voltage regulators, no diodes and no capacitors to smooth the current. There may a risk in charging lithium-ion batteries without a proper battery charging circuit recommended by the manufacturer. It worked fine for me, but if you try this on your phone, make sure you understand, and are comfortable, with the risks. Back up your data in case your phone is adversely affected and your data or equipment is damaged as a result. Use of this video content is at your own risk.By running an electric motor backwards, you can generate electricity.

Project History & More Info:

When using a cordless drill, remove the battery pack so you’re not fighting the back EMF, and press the trigger button in to allow the electrical connection to be made. Now all you have to do is twist the rotating end of the drill, and you’ll be generating electricity at the contact points where the battery would normally connect. On my drill, a cranking speed of 100 RPM yielded about 5 volts DC.

A few household items will make it practical to use. For example, a crank handle (made from a mixing beater and a salad fork) will give better leverage for cranking. Some aluminum foil that’s been rolled up into a wire will help direct the electricity to the point of use.

The faster and harder you can crank the drill, the higher voltage, and more amperage you can extract.

Ideally, this could be hooked up to a bike, water power, or a windmill to generate effortless energy, and if done carefully, the energy could be stored in a battery for later use.

    How hard is it to just buy a portable charger?

  2. Sorry was that 15minutes to charge the rechargeable AA battery?

  3. You have a old phone

  4. iHYP3RATE says:

    There's no way he did that for 3 hours straight with one hand with the attention span of regular humans….

    HALF LIFE 2.1 CONFIRMED

  5. ItZDeM0N1C says:

    at 4:17 it was 4:17 pm for me ?

  6. That's a lot to make holy crap 

  7. MCgyver phone charger. Thats legit

  8. can you do this with an exercise bicycle?

  9. Dr Dr says:

    Would this work with a corded drill?

  10. how do you run the drill backwards

  11. Lexie Cookie says:

    Or I mean, you could just keep more than one charger with you at all times..but this seems a little more fun

  12. rizwan anwar says:

    Really you are so rich and you only have a blackberry

  13. Xenerlicious says:

    I recommend connecting to the wires coming out of the generator to a multimeter to make sure you are staying at the correct voltage

  14. Is this free power? Not including the items

  15. Does anyone know where can I get the how to build a power generator from machiver

  16. alex white says:

    If I used the motor from my old dishwasher (which is HUGE), would it produce more power?

  17. u should atah that to a bike wheel

  18. Name Mrname says:

    Hey The king of random! I have an idea for a video you might want to consider! How about taking this idea to the text level by making a bycicle-crank generator? Im not talking about destroying it to make it, but if you could lift the back tire and petal it will go REALLY fast and then somehow make that energy into electricity?

  19. could you charge the drill battery by cranking it

  20. Ajax Ashford says:

    won't it charge faster if you put it in fridge first? the phone I mean

  21. I've been binge watching the king of random I love doing that

  22. probably you would love to make a video showing your musceles otherwise you don't have any

  23. TheGamer HQ says:

    Wow I've been with u for 3 years?!?

  24. JTRZ Jtrz says:

    Randomweekendproject?

  25. I had really bad stomach pains and diarrhoea but I watched you and now I feel better

  26. Dark Archer says:

    Or , you could just go buy one from the store . Just sayin' .

  27. Anmol Sidhu says:

    You are so cool ? man

  28. ShadeScale says:

    @King of Random
    Something I would like to see you attempt would be home made solar panels or even a combination of many small solar panels from calculators that could provide a source of power for emergency events.

  29. Well it almost worked
    ?
    ?

  30. Alex G says:

    I got an idea! Use a drill to power it, Then charge the drill at the same time!

  31. this is what makes burning calories important to generate electricity.

  32. ali10163 says:

    If you were to short the green and white wires the phone would draw more current and charge faster.
