Battery running low? Just add water to charge it up


Wouldn’t it be cool if you could recharge your Android phone with water? Powertrekk by myFC is a new fuel cell charger that does just that. This innovate charging system uses Powerpukks that contain sodium silicide which produce hydrogen gas when combined with any kind of water.

“PowerTrekk Water Charger gives your mobile phone power anywhere at any time,” says Björn Westerholm, CEO at myFC. “From now on, you do not have to rely on having an electricity grid nearby.”

The Powertrekk charging system was first introduced last year at Mobile World Congress, but it should be available soon at retailers across the US, as myFC will showcase the product at CES next week.

Overseas, the Powertrekk charging system has a suggested retail price of €199 and the Powerpukks go for €1.99 apiece. That means you can recharge your smartphone for less than the cost of a 4-pack of AA batteries.

The Powertrekk system might not be for everyone with its bulky size, but it should appeal to outdoor enthusiasts and people who spend time away from the electricity grid. Check out the teaser video below and then come back next week for some hands on time.

    This is fantastic!

    I want one of these, i can stop worrying that i might need to turn data off to get thru the day…

    Now thats what i call innovation

      If you are in a desert, and you are about to pass out from dehydration and you have a bottle of water, but you also have this battery that can juice up your phone to call for help, but to do so it will require all your water. Would you consume your supply of water to stay alive or would you fill up your battery to make that S.O.S. call but run the risk of becoming unconscious and dying? What would you do? What would you do?!!!

      • Tim Vacca

        One small sip of water for me and the rest for the powertrekk!

      • K1ngcor3y

        Drink the water.. Piss in the battery

          awesome reply dude :D

        I would make the SOS call several hours before I get dehydrated.

        Reply available a couple of posts down : Drink the water, pee in the battery

      • HReality

        I use Latitude.. they know where I am :P

  • http://clarklab.net Clark Wimberly

    wait, so the device itself costs over $200?

    • http://androidandme.com Taylor Wimberly

      No US pricing has been announced, but yeah looks like it could be around $200 USD for the whole system. Pucks could be like $1.99, but they will come in packs of 5, 10, and 24 so they could be even cheaper in bulk.

      • http://clarklab.net Clark Wimberly

        No matter how cheap the Pukk, a $200 upfront investment isnt going to fly woth most folks.

        • http://www.healthytiger.com Healthy

          also, call me crazy, but this kind of just sounds like a battery pack that you need to water. (and probably can’t take on planes.) Website says the fuel pack is about 1000mAh. (that is like 1 battery. i must be missing something here.)

          that and a upfront cost of $200 means they have a long way to go.

    • bemymonkey

      And I can’t find the power specs anywhere on the site – meaning that each “puck” will likely only provide a miniscule amount of power… a device of this size needs to be able to charge, say, a laptop battery (50-100Wh) in one shot. They’re talking about smartphones (~5Wh)…

      A AAA=>USB charger would probably cost about the same in the long run, with up-front costs of about $10 for the charger… $30 up front if you use rechargeable batteries.

      • kazahani

        The big draw here is not needing to have access to the power grid. I don’t think this is marketed towards the everyday consumer.

  • zyphbear

    This is pretty great, but I really hope that the pucks lasts more than once or then you end up having to carry around so many pucks you might have to have several methods of recharging.

  • spazby

    Too expensive…but great idea!

  • stenzor

    Now if they can integrate this into phones themselves, dropping your phone in the toilet would seem like a good idea.

    • http://androidandme.com Taylor Wimberly

      Yep or take the desert scenario above. Drink the bottle of water and then piss on your phone.

      • stenzor

        Bear Grylls would not want to waste that precious piss on his phone

        • Olliedcy

          So in reality this is just a scheme to steal our “precious bodily fluids”, right?

        • kazahani

          Damn you I made a Bear Grylls comment too!

  • classic_hero

    This is the future I tell ya!

  • Stella

    Awesome idea! Once the cost goes down, I’ll buy it.

  • Crístian Deives

    “which produce hydrogen gas when combined with any kind of water.”

    does _any kind of water_ also mean piss?

  • adam

    I don’t think you do much hiking. I know hikers with water bottles that cost more then that. When you have a tent worth $2000 this is trivial.

  • kungpaodragon

    AWESOME! May not be for me, but what an idea!

  • YNWA

    Hmm.. I just paid $155 for my new Galaxy Nexus, and now I am supposed to pay over $200 for a charger?

    Great idea, but way too expensive unless you are backpacking in the mountains. Oh wait, then there is no service. Hmm… Very limited appeal.

    • stenzor

      You don’t need to buy it man. Plus, it’s a new technology so it’s obviously going to cost a lot. Once economies of scale kicks in, these will be a lot cheaper… that is, if they catch on and people buy them.

      • DroidPower

        yea, definitely will be cheaper when more people start making these. Wonder if anyone’ll ever invent something to charge phones with just air.

    • honourbound68

      Ya. Very limited but might be useful enough for some.

  • z10m

    and the battery cell is only 1000mah which means that it wont charge iPhone 100%

  • lokidokie

    This wouldn’t be for everybody. But it is for me… Gimme gimme!!!

  • http://justinpulsifer.com/ ferman

    As awesome as this is they need to add a crank on one end so that if water isn’t available you are able to crank yourself some electricity.

  • sylar

    Cool but thats expensive for a charger that has one use tablets. Still very cool.

  • Chuxter

    And after you’re done chargine your phone you can drink the water as an energy drink!

  • droilfade

    Man…too many piss jokes! After auto mobiles going green…it’s your turn, Mr.’Smart’ Phone!

  • Ryan Phatbowler

    Great idea, wonder how long the discs last.

  • danielmkim

    Wow! This is cool.

  • nivekkev

    Sounded great at first but it is just to new, price for full unit too much right now. But I still love the idea and will keep an open ear for when the price drops to a more reasonable amount…

  • josegb2011

    Now my piss has a meaning in life…

  • z10m

    useless as the disc is only 1000mah
    and that wouldn’t charge your phone 100%

  • _Diego

    Cool, but expensive… especially if the disks are only usable once…

  • http://theinternet-allofit.blogspot.com Jorge Branco

    Not sure if it’s been mentioned but I just wanted to point out that’s possibly the worst ad I’ve ever seen.

  • druie

    this is awesome! i want!

  • Waspdroid


  • khanji

    great, i want it now for 10 dollars, thanks


  • vid500

    Great, what a incradible idea.

  • rzentz

    Sweet! Now how many do I need to buy to run a car?

  • aranea

    Because of its nature I don’t think you’ll be able to take this one into planes or other mass transportation vehicles. Think about it. Some one can rig it and blow up the H2 coming out of it.

  • smithey253

    If they can get that upfront cost down to a reasonable amount, I could see this really taking off.

    For those that are away from the grid for long periods of time, the 200 dollars is well worth it in my view. Beautiful piece of technology.

  • Hall Lo

    The concept itself is awesome, but the price…. :/

  • Thomas MacDougall

    if your carrying around the pukks you might as well be carrying around batteries so there is no convenience advantage

  • http://www.focuszonedevelopment.com Homncruse

    Oh come on, I can’t be the only one who read the diagram and saw “PowerPukk” and pronounced it “puke” instead of “puck”!

    Yay for power puke! Linda Blair would be proud.

    so nice, i like it

    so beautiful. i will so happy if i have a pair.http://www.battery-uk.co.uk

    I have a project to test a gadget that provides power to other gadgets using hydrogen. Visit the project and if possible help me!
