    I’m glad you put a really big cap across it so we could see the results. I was a little surprised it worked even though I suggested it in the first video. I just though that getting a steady output from a hand cranked generator was going to take more work than that.
    Now I want to hook one of those up to an exercise bike or treadmill and try charging some supercaps with it. I may need a good look at the inside of that thing to see if I want to just build my own or buy one eventually, I can’t remember what was inside it so I need to look at the last video again. Great video Paul, thanks for all you do for our electronics community here on you tube.

    How about placing the big cap inside the box, inbetween the motor and de DC to DC board inside? Or in parralel with the small one inside, between the polarity diodes and the DC to DC?

    Hi! I was looking for tests and reviews about this crank generator. Thanks! Now i want to buy one...
    Could the capacitor be installed in the generator case itself, at the output of the DC motor directly?
    Or does it have to be after the circuits to stabilise the voltage?
    I was wondering about the damages that could occure while tryin to charge a USB device...
    I'm not good at electronics,
    Hope this is not a dumb question.
    Thanks again from Belgium!

    I'm not surprised there is not a lot of filtering added circuitry on these coming from China.
    I built my own hand crank generator and included a super capacitor bank that stores the charge. I can run a LED lights for hours with just a 3-5 min cranking session, or partially charge a phone. I added a regulator for the USB voltage.

    It doesn’t really matter about the ripple because you’re going to use it to charge batteries or Supercapacitors anyway.

    About that, once I saw a video where the guy shows how he made a hand crank "box"... The difference is that he put a HUGE ultra capacitor bank inside... When 100% charged he could even start a car with it. LOL
    But, of course, he put a DC input, so he don't need to crank all the way up. 😂

    I want to learn electronics but i'm currently too much of a beginner to understand how the circuit connects, looking at that breadboard. Can you link a picture or sketch of a circuit that shows what connects to what, in what order?

    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.

      10k, as in 10,000.10,000 uF = 10k uFSpacing is key.But to answer you, yes it would be 10 mF. Most of what we see here is marked in uF until you hit a certain value, which, at this point, escapes me since I haven't had to deal with them in a loooooong time.

    Just realized. The sound the generator makes is similar to the sound the engines made on the original NCC1701 when under distress.

      You never know. Foley artists are amazing. When I was a kid, I was messing around in our garage and wacked one of the door springs with a stick. The sound it made was the sound of blasters from Star Wars. I was like "holy cow!, so that's how they do it"?
