Hand cranked Emergency Generator

[@nicksanto882]

If we could put one on a street corner next to an elementary school with a “do not crank” sign on it....... we probably wouldn’t need power plants any more.....

[@learnelectronics]

haha for sure!

True i probably would be there every day

[@chadwarren9677]

I have this fantasy that cities could build human power generators where you walk up and push on a horizontal handle connected to a generator. It would be a functional symbol for what people can do when they choose to co-operate like a new kind of electric church.

[@Chastity_Belt]

OH MY GOD I JUST LAUGHED MY ASS OFF 😂

[@lindabarcelo5952]

You might want that longer handle once you put an actual load on the generator beecause more force will be needed in turning it to counter the back-EMF generated Also, since it requires one hand to turn the crank while the other hand holds the unit, it can be easily operated on the edge of a table or countertop.

[@goshgosh9422]

[@valveman12]

Be aware the USB port is not separate from the output connectors which means if you select any voltage, that will also show up on the USB port. Ensure you have the voltage set for 5V or you may destroy the USB devices you wish to change.

[@gg-gn3re]

yea he says that..

[@christopherleubner6633]

Yikes! That is a very serious design flaw.😮

[@deskmat9874]

To be fair it's your fault if you kill your phone by charging it with 12V instead of switching the limit to 5V which is what they're meant to take

[@object77b81]

[@kristafoster7190]

How about putting a model p.m.r live steam boiler and steam engine on it from pmr research .com to get a one research live steam engines and minature gas engines it be cool to hook a steam engine to it pmr research .com can have a belt pulley custom made for your generator and it be continuous small compact off grid power generation system with a miniature live steam engine that be cool to run it about a 1000pm

[@Rick88888888]

You forgot to test the most important part, i.e. how it performs with a load attached. I'd like to see how long you can sustain turning the handle while loading someting with 20 Watts...

[@GadgetAddict]

Is the gearbox using metal or plastic gears?

[@somethingabstract3735]

Plastic

[@diegoalonsomunozramirez8188]

It´s plastic, have two planetary gears

[@DavidWatts]

Nice, I have been searching for a little hand crank generator (just not one of those plastic ones) for ages. Looking forward to your current tests.

[@learnelectronics]

Thanks David. This thing is quite well built, but the output is not quite smooth. You will see in the next video, but the ripple as around 400mV.

[@ExplorerOffgrid]

my first thought was to use it as a inexpensive windmill

[@Athrunwong]

Patrick Luke Spend more money on weather proof that thing than the generator it self.

[@slicksticky7298]

Same.. lol.. looks like a standard fan blade would mount up pretty easy.

[@kaoshavoc]

As you put more load on it, it should get much harder to spin, that is probably why they put the longer crank on it. Love your videos mate. :D

[@learnelectronics]

Thanks!

[@illygotbeats]

******Maybe someone here can help me*****. I bought this for emergencies. I tested it out the box due to a coincidental power outtage when it arrived. I wanted to charge my phone. I set it to 5 as it says everywhere to do. I cranked for 30mins desperate to charge my phone and all it did was continue to lose power. The phone said it was charging but just kept dying. I've tried it on several devices since then and it's the same story and there's like no info online about this issue. Any ideas? Or ideas for a fix?? Side note. On devices with more than 50% power there is more resistance, but its not consistent!! Sometimes it slips like it's charging a dead battery then goes back to stiff again. Thank you for any potential advice!!!

[@Sertao2013]

You don't have to worry about the voltage setting on the usb ports. That setting has nothing to do with the usb ports . it has a regulator that keeps it at 5 volts .

[@theirisheditor]

I'm surprised there are not any exercise bikes on the market that use a generator for resistance instead of magnetic or friction based resistance, at least not around here in Ireland (or UK). With a generator that could power a TV or recharge a laptop, I'm sure it would work well to encourage working out, even if the electric bill savings is negligible. Like this hand cranked generator, it would provide power during a power cut. Being pedal powered would also provide a lot more power, probably around 100 to 150 watts based on one KZbin video showing a DIY pedal powered bike powering an old CRT TV along with a few incandescent light bulbs.

[@dennisyoung4631]

I have thought of doing something like that for my own use. Thanks for telling me I’m not totally full of

This very much interests me. I was looking at getting one of these for our winter power outages.

[@tkoll6268]

Very affordable lol

[@ApO__]

Aghhh, It hurts me to say it, but this review was kinda sloppy and in general, not very useful. Why there was no actual test with a load?? Can this thing keep the voltage stable, when you power something? Also, when you connect a load, the force needed to spin that motor, would be much greater and you will appreciate the long handle. :) Cheers

[@learnelectronics]

You must have missed the part where I said we would do further testing tomorrow.

Perchè si limitano sempre ad una manovella per generate energia? che fine hanno fatto i giocattoli che si caricavano a molla?

[@Inkling777]

I have an older version of the K-Tor "Power Socket" hand-crank generator. It is U.S.-made and rugged, but it unfortunately illustrates the problem with hand generators. It's a lot of effort for a little result-1 amp USB output cranking like mad. The makers are right. Fifteen minutes of cranking will charge an iPhone well enough to make a quick call. But I did some calculations. Fully charging it would take almost an entire day of cranking. There's also a core problem with hand generators. You can't do much of anything else while hand-cranking. A bicycle-like generator is better. It leaves your hands free for other tasks and legs can generate more power than arms while getting less tired. The company that made my hand generator does make a sturdy pedal generator called the Power Box 50, but at $395 it is a bit costly.

[@hellrazor117]

3:22 what does he mean by having the switch in the right place? If I wanted to charge a 5v phone does it mean I would need to set it up for 5v and no more?

[@andychow5509]

Yup. That's exactly what that mean. If you set it to 6v or higher, you'd fry your phone, potentially damage or make the battery explode.

[@hellrazor117]

[@oplkfdhgk]

but wouldn't the torgue needed to spin the handle change with the power usage? so maybe it needs that big handle when you are using the max power this outputs?

[@robertcalkjr.8325]

Thanks Paul.

[@gigiachaddicus2424]

what size screw do you need?

[@Trac3r.]

What do you think is the biggest appliance you could get away with? Is it possible to give 240v? I know probably not but if it’s only good for usb definitely what else would we apply this to

[@walterbrown8694]

Just remember, boys and girls, - 745 watts (0.745 kw) is the maximum power available from the input of 1 horsepower to a generator. The maximum power that a human can provide is well under 1 one horsepower. Keep this in mind when you consider and plan for your Emergency Survival.

[@1mulekicker]

You might try a fire starter bow drill since there is no negative current going backwards. Like sawing a log, longer the bow easier to use. Try a oversized rubber grommet on crankshaft.

[@PabloAgustinjr]

How much that little machine generator sr where you buy. 😊

[@coondogtheman]

You should get one of those little mini steam engines and make a charger out of that. Exactly how much torque does it need to spin to charge something?

[@aberdeencompassionsociety]

Were could I purchase this item

[@mikeoliver3254]

I love new scope days. Looking forward to seeing some current testing. I wonder if adding a current requirement will make that longer crank handle make sense? That looks like a fun box to play with. I wonder how hard it would be to 3d print a gear set and box to make one of these things at home? Well at the library for me when I can get some printer time (when it is working 😒). Thanks for another great video Paul.

[@christopherleubner6633]

You can build one of these from a stepper motor salvaged from an old copier or laser printer, 6 diodes, a crank and a capacitor. Add a car usb charger to get 5V for your devices. ❤

Make sure you put it on top of a cardboard box or a roll of toilet paper and never at the edge of a table. They void the warranty if you use your head even a little.
