These are extremely handy to have. The crank generator super capacitor flashlight that I made years ago on my channel, I still have and use it. Great job, I really like how everything fit nicely inside the crank gen unit, and the long run time.
The shot where you took your small flashlight to a wooded-area, my brain went like "Oh no no no... it's bad enough when horror games make you choose between a flashlight and a weapon at once (think Doom 3). Imagine if you also had to worry about cranking it..."
Awesome, glad to see you're doing good. I'm not sure if enough people realize the use of such a device. In the right circumstance I can imagine some people begging for an opportunity to receive some kind of power even if they have to crank their arms off. These dynamos and supercaps are def the way to go.
It's been a while! Your voice brings back the memories I have during engineering school. 7 years later still referring to your videos for ideas. Thanks inspiring us. I'm currently working on your idea of water activated battery, thinking of what else I can do about the technology. Welcome back!
Thanks for the video .I bought one of those and took the hand crank off and attached a sprocket that is belt driven and attached it to a wind mill and as long as the wind was blowing I was able to generate power and do use it to charge my deep cell batteries .😀
I wonder if this objects or something like it could be hooked up to your vehicle and some place. Basically charge up something besides the main battery so that you have emergency lighting besides just using the main car battery. And on another note, I wonder if any car companies out there possibly created and tire battery for an hood on a vehicle.
You can also use an old cordless drill with dead batteries as a cheaper/free alternative, just zip tie the trigger down and wire up what you want to power to where the battery terminals would make contact in the handle, I really like the old drill technique because it’s easy to put a hand crank or a pulley onto the chuck of the drill plus often drills have some gearing you can play around with - love your stubble field content by the way!
LaserSaber, you have given the world a gift. We’ll take the salad dressing, just getting thru to 110v is so impressive I’m speechless. Of course we’ll be on 5v but Cheeziz man, you show the way) Cheers
Welcome back lasersaber! 👏👏👏👏👏👏 so good to see you back here! Thank you so much for this video, I have the exact same little generator, so I’m really looking forward to doing this mod to mine .
The efficiency with which humans are now capable of creating usable bright light is incredible. A 1994 paper by economist William Nordhaus lays out the case meticulously. From the camp fire, to the oil lamp, to gas lighting, to the incandescent bulb, to fluorescent light, to the LED, there has been a roughly MILLION-fold decrease in the cost of lighting in terms of energy and time required to create light since antiquity. There is probably nearly a factor of another 2X efficiency gains still remaining in electroluminescent lighting before theoretical limits become dominant.
That's really cool, it's nice and decent of you to tell everyone that the contest and selections were already over also. I thought you had started using the large electrolytic caps instead of the super caps because they charged faster. I wasn't aware you had uploaded a video until I watched Lidmotors' latest video, he's making one too, thanks.

Hi Lasersaber I have the same hand crank gnerator and I am considering adding capacitors to it as you did. Question: How has the generator been working given there is not capacitor charging/protection board?
Does this thing use a low dropout voltage regulator, .... a buck converter or just a resistor to regulate the voltages? It might be possible to squeeze out some extra efficiency using a buck converter & smoothing capacitors for the 5V regulation?
Got one now...but the small capacitor is now soldered to the board. I was able to get the board out with a little bit of gentle wiggling. Will solder the wires, then put the back the PCB and then solder the super capacitors.
Hi Mr. lasersaber, I’ve been following your incredible videos on supercapacitors and truly admire your expertise. My client is exploring large-scale supercapacitor manufacturing, and your insights could be invaluable. Specifically, we’re curious about scalability (large units vs. clusters), real-world performance vs. traditional batteries, and challenges in production. Would you be open to a quick discussion? Looking forward to your response!
Neat video Lasersaber, I ordered all the parts you listed to recreate the experiment minus the 250W inverters. I am adding 2 more 100F supercaps and am adding 2 banks of 5 in parallel for the increased current capacity at 15vdc max. Any chance of overcharging the caps in this configuration? I may add some over charging prevention circuitry. Can you list your inverter sources Lasersaber?
Very impressive, one question though... i remember when u used supercaps in series, you always had some diodes or similar stuff to avoid overcharging a single cap, or at least to balance the charge... ist this still needed? (that was years ago) and would a balancing circuit for all caps use more electricity than you can crank? Thanx for the video Luc
Good question. I have done long term tests with and without balancing. My thought is that the closer you come to the full charge state equaling the max voltage of the pack the more important balancing becomes. In this unit the full charge state is around 15 volts. The 8 super caps full charge is around 21 volts. It probably would have been better to go with 6 super caps. This was my first build and after testing the no load generator output voltage and seeing that it was around 20 Volts I decided to go with 8 caps. After testing If I was building this over again I would probably go with 6 caps and no balancing.
this is excellent for emergencies even for a small air compressor and adding a small air tank to inflate your cars tire back up when running low on air. will have short run time but very use full even for radio equipment use like for ham radios hand held ones.
Okay noob question, so go easy. I know that the total capacity goes down as you add capacitors is serials to get higher voltage. So, if your goal is using the 5v USB port, do you have more storage with 6 capacitors instead of 8? Thanks for coming back!
No you would have less run time. Instead of 20 minutes plus you'd have probably 15 minutes. Adding more in parallel 8 + 8 would give you more run time, probably 40 minutes plus run time. Not sure if you would need to reduce the 100f to 50f though.
If you put two 100F (3V) capacitors in parallel, you would have 200F (3V). If you put two 3V 100F capacitors in series, you get 6V 50F. So 100F divided by 6 is 16.67F (18V). LaserSaber might do better to use a 3S2P arrangement of 3 serial groups of 2 caps each, 200F/3 = 66.67F (9V). If he had a buck-boost converter bringing the energy back out, he could use 2S3P, at 300F/2 = 150F (6V). All this math assumes the new 3V Tecate supercapacitors (at Digikey) are used.

@@lasersaber Probably keep the 8 caps so if ever u feel like charging it for longer, you get to have more power stored. If you go with 6 caps in the future, you would be charging near the full caps voltage right? And would have issues or need for balancing.
Why is this better than plugging in a powerbank into the USB port and charging it up, then using that for the light bulb? Also I saw this advertised as brands Vobor, Regun, Nisorpa, YaeTek, Banggood etc etc. Why?
I hacked together a charger from the lower part of an exercise bike ( base and crank) and a 100V DC treadmill motor. The poly-V belt from the bike fit perfectly on the poly-V wheel on the motor. 15 RPM on the pedals charges a phone completely effortless through a car USB adaptor, so this can be done while sitting on a desk or in a recliner. I too added 6*350F super caps + diode and a "%" LCD battery meter to have a buffer, so I could pedal in bursts. The USB adaptor worked from 16V down to 7V on the caps. I also tried charging a laptop at 19V directly by holding the RPM constant , but without regulation, it was too sketchy for the survivability of the laptop, but still doable at 60-100 RPM, like a brisk walk. Not very portable, but excellent as a blackout generator for home use, just to keep the basics running.
Thank you for this video! Really cool idea for emergencies. I just finished my first one and it is really cool! Got the stuff to make a second one. The handle did break on me, so I'm open for any ideas on how to make a new handle for this... Lol. Think you can somewhat safely jump start a car with this?
Gearing & a flywheel, like a bike + super capacitor bank should improve efficiency and ease of cranking. Also I buy those little motors for small cnc machines for a lot less than these units do
"The supercapacitors, under standard testing at ambient and rated temperatures, and application testing at ambient temperature, have undergone approximately ten million, 11 million, and one million cycles, respectively, over two years. The supercapacitors did not experience end-of-life failures but remained within specified operational tolerances. The study was terminated after successfully completing 11 million cycles at approximately 75% DOD at rated temperature. The results demonstrate cycle lifetimes significantly in excess of manufacturer specifications and potential for deployment in long-life robust applications."

@@lasersaber Thank you so much for the info. It means it can sit for years waiting for emergency or when needed will be useful for as long as needed without the need to replace crucial component.
It took me 3-4 minutes to reach 15 volts. That is pretty much a full charge for this unit. In theory it could go up to just over 20 volts but that would take way too long at this gear ratio.
Instead of turning it by hand can u hook it up to a cordless drill to spin it that would be cool ! Love your videos your actually creative and experimenting 🧪
I kinda feel like just using a 10w foldable solar panel, small power bank, and usb flashlight would be easier, cheaper, and the light would last for hours without any effort. Maybe I'm wrong tho. I really love your innovative ideas, keep them up!
Hi @ lasersaber, thanks for the video. I like to build it one for emergency purposes, but wondering if I do need to attach a diode so that no current flows backward. One more thing, is possible for the supercapacitors to explode if the crank is rotated continuously like when attach to a bicycle or make is a generator from a water paddle wheel?
The link provided for the Super Capacitor is a 3V but the original in the device is rated 35V and measuring the voltage output by the motor can spike over 12V is there something I am missing or is it the wrong part?
You show charging a phone without the supercaps, but not with them. Phones won't draw too much current at 5V (slow charging), but are still a relatively heavy USB load. Could a drained smartphone be charged enough from 1 minute of cranking to boot up and make a phone call?
@ lasersaber Have you got a chance to test these new age supercaps called zoxcell rated at 3000f 2.7 volts .and 21000F 4.2 volts , looks very promising as they are very small for the density they hold.Can you make a video using those cells if you can .
i have the same dimensions of super capacitors from ZOXCELL (1 cm more in lenght ) and 3000F 2.7Volts i dont know if this capacity is real or fake and in their website they have also 10000F and more so is the dimension important, i dont know
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.
Hello 🎉 Thank-you thank you for your video shared for us all .. was wondering what the difference is between the 500f super capacitors and would these work better or worse on this mod for this dynamo, generator cheers 🍻
it would be more interesting if it were applied to a gravitation system: a clock that by letting a weight go down, for 10 minutes, recharges the battery. Anyway congratulations.
try aluminium-foil separator-paper spiral roll with ethanol-koh electrolyte to make aluminium-air battery, soaked in a standard lead-acid plastic container, with a separate carbon air-electrode, just make sure the separator paper lets the electrolyte flow between the foil layers
try dry supercaps, aluminium foil, anodize super physical aluminium dioxide dielectric layer, coat with water or liquid conductive paint, ie, dry actual capacitor with super thin oxide layer, and the liquid conductive paint drying super close to the oxide layer
energy density will be the metal itself without the air and count the supporting pieces as engine weight, not the metal weight itself, even if you could calculate the total specific energy based on the total weight to energy ratio, with the pieces included, aluminium should be 3-4 kWh/kg easily, keep the air electrode around separate to the paper-metal layers, and the ethanol-koh (non-aqueous essential) reasonable, also around the paper-metal layers, you can even arrange so that the metal-oxide drops down to the bottom of the container after it has formed, if you have enough space between the layers
if you dont make the fixed primary cells of the spiral metals, you can feed in the fuel metal foil or mesh-wish (for high surface area), and even filter the electrolyte to remove the oxides, even iron wire or iron foil will work, as iron-air continuous feed fuel cell
These are extremely handy to have. The crank generator super capacitor flashlight that I made years ago on my channel, I still have and use it. Great job, I really like how everything fit nicely inside the crank gen unit, and the long run time.

what about capacitor voltage balancing ?
Is there a way to charge up like an ecoflow solar generator battery bank by using super capacitors paired with an inverter?
Did you consider connecting them in parallel?
connecting them in parallel would increase storage power capacity but would reduce the charge voltage tolerance

The link provided for the Super Capacitor is a 3V but the original in the device is rated 35V and measuring the voltage output by the motor can spike over 12V is there something I am missing or is it the wrong part?
How many of those capacitors would you need ?
You show charging a phone without the supercaps, but not with them. Phones won't draw too much current at 5V (slow charging), but are still a relatively heavy USB load. Could a drained smartphone be charged enough from 1 minute of cranking to boot up and make a phone call?
can we get an update on the various long term motor tests and their batteries?
mobile charge, how much time does it take after booster capacitors are installed?
Awsome upgrade, thanks for sharing
Are any of the crystal batterys still going?
Have you tried charging a 10,000 mAh power bank? I wonder how long you will need to crank.
that would take a long time!
Thanks. Great project. I just put one together and it works great!
How many minutes it will last?
Capacitors in series?
Can you greatly boost the range of your EV by adding super-caps in parallel to the EV battery module? Would love this idea coming to life!
We're you able to charge your smartphone?

lasersaber Have you got a chance to test these new age supercaps called zoxcell rated at 3000f 2.7 volts .and 21000F 4.2 volts , looks very promising as they are very small for the density they hold.Can you make a video using those cells if you can .
Thanks for telling me about them. I’m checking them out now.
How many minutes it will last bro
i have the same dimensions of super capacitors from ZOXCELL (1 cm more in lenght ) and 3000F 2.7Volts i dont know if this capacity is real or fake and in their website they have also 10000F and more so is the dimension important, i dont know
Hey man, thanks for the great video. I got the crank generator, i was wondering if i could use 100uF 25V instead of 3V capacitors?
no these are regular capacitor for filtering, we are talking here about super capacitor, and you have to make difference between 100uF and 100F
Just wondering, how much does it cost to make one of these?
can i use it on electric kettle
Hi, lasersaber is there any working links for the sol125?
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.
Capacitors connections series???
yes amigo
Hello 🎉 Thank-you thank you for your video shared for us all .. was wondering what the difference is between the 500f super capacitors and would these work better or worse on this mod for this dynamo, generator cheers 🍻
it would be more interesting if it were applied to a gravitation system: a clock that by letting a weight go down, for 10 minutes, recharges the battery. Anyway congratulations.
Finally, a way to put that hamster to some use!!!
lol..i use cats!
You can use lto battery ,whay not?
I like using a stepper motor as a hand crank generator.
wish I could donate via paypal, without the middleman...any chance of that as a future option?
try aluminium-foil separator-paper spiral roll with ethanol-koh electrolyte to make aluminium-air battery, soaked in a standard lead-acid plastic container, with a separate carbon air-electrode, just make sure the separator paper lets the electrolyte flow between the foil layers
try dry supercaps, aluminium foil, anodize super physical aluminium dioxide dielectric layer, coat with water or liquid conductive paint, ie, dry actual capacitor with super thin oxide layer, and the liquid conductive paint drying super close to the oxide layer
feel free to patron if you find this useful
energy density will be the metal itself without the air and count the supporting pieces as engine weight, not the metal weight itself, even if you could calculate the total specific energy based on the total weight to energy ratio, with the pieces included, aluminium should be 3-4 kWh/kg easily, keep the air electrode around separate to the paper-metal layers, and the ethanol-koh (non-aqueous essential) reasonable, also around the paper-metal layers, you can even arrange so that the metal-oxide drops down to the bottom of the container after it has formed, if you have enough space between the layers
about the dry supercap, the thickness of the oxide should be similar to the double layer of the wet double layer supercaps
if you dont make the fixed primary cells of the spiral metals, you can feed in the fuel metal foil or mesh-wish (for high surface area), and even filter the electrolyte to remove the oxides, even iron wire or iron foil will work, as iron-air continuous feed fuel cell
Wait WHAT??? When did you come back??? I’m subscribing again then.
yes i was shocked to his videos turn up again in my recommendations..i virtually forgot the channel through the few years of absentia!
