Make an Emergency Phone Charger – MacGyver Style!


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. www.thekingofrandom.com Music by Jason Shaw (RP-ThinkTank) http 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. 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

    USB always supplies around 5.0V, the only thing that changes is the mA output. USB 3.0 for example can supply more amps than 2.0.

    But only insufferable bores know such things. History is as much about the story as it is the facts. And my point was a good one. Learn to see the big picture.

    It was kind of pointless of him to sit there and crank for 3 hours, he already knew it was outputting the same voltage as the actual phone charger (as shown by the volt meter), so logically it would take the same amount of time to charge as when you plug it in the wall.

    Could you do this with a drill that plugs into the wall with the same setup?Using the “prongs” on the wall plug.

    Will this work with a larger smart phone or an ipod? Maybe a laptop?

    Edison didnt invent the lightbulb, Tesla and like 10 other people did before him. I hate when people say that. Edison bought their patents and sold the lightbulbs

    Try to attach some nice condensators to make power more stable. This way you dont really help your phone battery to have long life :D Btw nice vid ;)

    Short the green wire and it’ll charge faster (fools the phone to think it’s plugged in ac instead of usbs rubbish 500ma max).
