Crank Up Battery

Re-chargeable batteries are no good when they run out of power and you have no electric point handy to tank them up again. Here’s where the concept of the Wind Up Battery steps in; re-charge these cells via the conventional battery charger OR use the hand-crank to wind up and source-up some juice. Kinda like your hand-crank radios. A simply superb concept!

    the problem is less battery storage and more parts to break.

  • Why, oh WHY would you use RED for full and GREEN for not full???

  • beni says:

    Isn’t red a Chinese thing since the author seems to be from there?

  • Frank says:

    I have to wind it for 20 min to get 100% power? no thanks. Thats just one battery.
    Not to mention the red for full and green for empty

  • steve-e says:

    I don’t think capacity would be such a problem. You look at the latest rechargeables, now 2600mAH, where they were 1500-1800 a couple years back. So in that size you could probably still fit around 1800mAH with technology around now.
    Not sure about the time taken to charge though.

  • CSB says:

    I love this idea, but really, how many cranks would it take get any decent charge into these batteries?

  • No_7 says:

    Rather than hand cranking, I’d prefer a short string (maybe a foot or two) and a small weight. To charge it up, you’d hold onto the battery and swing the weight around while day dreaming you’re David facing down Goliath. Take THAT Duracell!!

  • IslandMisfit says:

    Awesome idea, except, ditch the handle and just make the rotating end rubberized, then hold the battery end and run it across a hard surface (like charging up a wind-up toy car)

    bam! more room for battery power, less parts to break, and you wont look like an overgrown kid with a miniturized jack-in-the-box…

    • Lin says:

      or like a pull string thing like the ones on gas lawn mowers that you have to pull to get it started

    • Kendall Fleming says:

      I like that idea…..but what about devices that use more than one battery? You’d have to do the same thing for each battery…what about charging all of the batteries at once?

      Maybe you could have a docking station and use the concept that No_7 or IslandMisfit stated.

  • Gary_7vn says:

    What this needs is a battery powered winder! LOL

    Seriously this is brilliant. I have a bike light that cranks, 30 seconds will get me about 10 – 15 minutes of useful light. These might not be practical for everyday use, but they would be perfect for survival/camping/military uses.

    And while I am at it, where is my crank powered cell?

  • smirkette says:

    Brilliant & simple design. I would buy it, although 20 min is a bit much. 10 min seems more realistic.

  • Heliophage says:

    Fully charged in 20 minutes of continuous cranking? That seems a bit tedious… but I excuse it for the fact that it’s attractive and surprisingly practical for situations where you need batteries and can’t readily buy new ones or charge more traditional rechargeable AAs.

  • Carl says:

    so battery of the same size to house a crank mechanism and the battery it charges. so after 20mins how long will this battery last compared to regular rechargable batteries? this concept is a wind up

  • Matthew says:

    I’m sorry, but red for full and green for empty is just bad design. It worries me that a design company would even think of reversing a standard like that.

  • Chung Dha says:

    I rather use my solar charger or buy cheapo batteries everywhere at anytime.

  • Chase says:

    Where can I buy them?!

  • magibod says:

    Seems good for a survival situation but I’d much rather use an innovative and easier to recharge battery like the USBCELL which you simply use by recharging in any USB port

  • Mr Realistic says:

    Beautiful concept, but:
    I’m surprised people are whinging about 20 minutes of cranking for full charge.
    That’s not gonna happen, not in a lifetime. 20 Minutes of cranking would get you maybe 4% if you’re lucky.

    The kinetic energy produced by turning a crank is nowhere near the electric energy provided by a wall socket outlet.

    The only way 20 minutes could equal 100% charge is if these batteries hold very little charge.

    And what battery technology is proposed, Alkaline, Lithium, NiMh or Lithium-ion? Or something else?

    Beautiful design and concept but zero practicality.

  • myNEWiPhones says:

    Creative and Innovative design

  • Moises says:

    im sure they could invent some sort of auto twister or a tool that helps you twist it quickly… 20 minutes sounds like a lot

    • Whichever says:

      Yeah and that “auto twister” will be…crank powered?…battery powered?…solar powered (if that is the case make the batteries solar powered)?

  • adam says:

    This is ingenius, I love it. Like a lot of comments though I think I’d get bored or tired to do it for 20 minutes on each battery. Love the thinking though

  • ZXT says:

    But the question is, how much is it?

  • ryan says:

    cool idea, but it would probably break pretty easily, and after 20 minutes of twisting, i think i would just stick to rechargeable batteries.

    • Madrigorne says:

      Modify an ordinary windmill to turn the crank in a survivalist setting and you are good to go – let it wind in the wind for 20 min.

  • will says:

    that would suck for my r/c airplane controller that uses like 8 AA’s

  • scarabeetle101 says:

    they should replace the crank with a small gear on the end of the battery so that you could either slot a crank on or stack lots of them into a larger device with one crank and a high gear ratio which would result in faster charging. Then it’s halfway to steampunk too, which is always a good thing.

  • Rona says:

    Special design. There’s something with unique design here:

  • JDK says:

    It’s amazing what can be accomplished with kinetic energy.

  • Zach says:

    How much does this cost and how can I order them from here?

  • derko says:

    Pointless. Tiny parts will break after first recharge attempt.

  • Dear Qian Jiang,

    Can’t wait for the large (more durable / more winding required / more powerful) version of this.

    20 mins to need a re-crank is excessive. Try 8 hours of power as a target (incorporate bicycle gear based concept for lowering cranking time too), otherwise it will never take off. Half an hour of cranking should be the maximum. Don’t exceed that mechanical ratio.

    Then also consider multiple batteries tied into a modular and detachable system to power larger devices, like mobile air-conditioners and heaters.

    But it looks like you could corner the market if you work fast, and keep production prices low (something China is unbeatable at so far) and quality high enough to last a lifetime. Don’t make things that fall apart, its SHAMEFUL to China.

    Alright, so we’re all waiting for you to free us from being slaves to the energy companies, now hurry !

    If you need investors, please contact my email, am quite interested in the success of your mechanical battery . . .

    Best of luck and don’t let jealous or disparaging remarks affect you, almost saving the world here.

  • So how the hell much does it cost!?

    Why do I keep seeing this everywhere, but nobody is listing the price or where to buy it?

    This should be more developed, but is sure promising and probably good for the environment.
    Batteries can do so much.
    Thanks for your contribution.

  • Tiny Mcfann says:

    You could certainly see your enthusiasm in the paintings you write. The world hopes for even more passionate writers like you who are not afraid to mention how they believe. At all times follow your heart.

  • Dave says:

    A similar product exist in market under the brand- QUECHUA.
    But well thought..

  • Lora says:

    How much doest this cost?

  • Bill says:

    Plus a ridiculous high price and people quickly getting bored with charging for 20 minutes.

  • Hoag says:

    You’re right about the color choices, but more importantly, this is a *battery*. Why would you waste power on a light indicating that it has charge??

  • The whole LED scheme is bass-ackwards. It is steady green when dead, flashes when it’s charging, and red when it’s charged…

    Other than that, it is a pretty decent idea. Maybe not for every day use, but for emergency equipment it may be nice as you never have to worry if the batteries are dead when you need them..

    Hello mates, its impressive post about educationand entirely
    explained, keep it up all the time.
