Bicycle dynamo charger for your smartphone

There are many cycling-related apps, but very few ways of recharging smartphones and tablets while on the move.

ipad bicycle chargerThe £100 Cycle Charger from Convergence Tech looks like a conventional bicycle dynamo, but has been designed to charge any mobile phone, iPod, iPhone, Blackberry, GPS or other similar device.

Cycle Charger specifications:

• Female cigarette lighter socket (just like in a car)
• Runs and charges your device as you ride
• Includes a voltage regulator to ensure that your device is never damaged no matter how fast you are riding your bicycle
• Produces up to 15 watts, which is far more than most devices will ever need

    A dynamo charger would be the perfect gift for myself since I spend long hours at work and I cycle to and from it. Being able to charge it along the way will ensure I stay connected to my family and the rest of the world. 🙂

    I would like one so that I can always be reached by phone on the go. It’s very annoying to go out for the day and worry about your phone’s declining power levels after a few hours.

    I love cycle touring but when you are out in the middle of nowhere on a winding road miles away from a town and sleeping in a tent, it’s awfully hard to charge a phone. This would be perfect, using the power of my legs to charge the phone by day and send text message updates and instagrams of the trip by night 🙂

    As I struggled up the most difficult hills, I would know that my muscles and sweat were their most useful yet, charging my phone as well as getting me up the hill.
    And on the easy downhill rides, well, how could anything be more free than wheeling and charging and knowing no dirty volts had to be inserted to make this little gadget come to life?

    That’s a brilliant gadget, would love to have this charger! Often go away camping with the bike and obviously charging phones off grid can be problematic in this less than sunny climate and this would be a great (and very green) solution! I’m guessing if it’s a standard cigarette lighter style socket, you could charge other USB devices like bike lights?! Ingenious!

    Like so many great ideas this is so obvious when someone else has thought of it. I too can never track a full bike ride (let alone a cycle camping tour), because my iPhone doesn’t last any time when tracking or navigating. I have thought about fitting a little motorcycle battery to the back of the bike with a car power socket adapter attached, but one of these would be much better.

    I would really like to win this prize, last year I converted to a recumbent trike, bought through social funding, because I had been unwell for many years.

    Since then, I have gone from strength to strength. But I still have the issue, I cannot fit a dynamo hub to my trike, because I have two front wheels, I need to keep them both very balanced.

    This restricts me from doing long rides, because my lights, phone and other things always need charged. But being disabled, I cannot go exploring the wilds on my own without having a means of contacting someone, just incase anything should happen to me while out cycling.

    Great idea for keeping the Garmin Sat Nav and Mobile phone batteries going on a long ride. I rely on both so this device provides the extra confidence that my gadgets wont fail through lack of power. I am looking at some long Audax routes next year, this looks ideal companion.

I’ll be honest, I LOVE my phone and it goes everywhere with me. But that also means my charger has to come as well! These little gadgets use so much juice, being able to go out on long rides and NOT have to worry about being stranded without power on my phone would be amazing. On a more serious note: I commute to work, with it being dark when I leave for work and when I leave to come home, knowing my phone will always have battery would make me feel better, safer in fact. Plus I can use all my cycling apps till my heart’s content without worrying about that dreading battery drain beeping…. Bliss! 🙂

    The cycle charger is a really good idea which is likely to be a ‘must have’ gift for cycling enthusiasts, cycling commuters and busy, cycling travellers who need to have long periods of their journeys away from a regular power supply. It’s looks and price may currently be a bit off-putting – but healthy sales will perhaps help further design refinement and perhaps get make the price more attractive.

    This would be great to win! No more running out of battery because my gps sucks all the battery from my phone. My brother in law and myself trade he maps the first half of the ride i map the second and we hope the batteries last otherwise we have to wing it at the end! Not to mention the obvious ‘save the planet’ implications of less regularly using the home plug sockets!

    I went on a diy grassroots bike tour around Europe this summer and charging phones was a real issue for most people – as we were using our phones for all sorts – taking photos, blogging, gps and mapping as well as keeping in contact with others ahead/behind on the road. Wild-camping meant we often wouldn’t be able to charge for days and the solar powered charger we tried couldn’t keep up! I would donate this charger to the group as this would make such a difference, and everyone gets to benefit from it, especially as the price would be unfortunately out of most people’s grasp on the (yearly) bike tour. The tour is self-funded, runs for around 3 months + and aims to have as little an impact on the environment as possible – so of course a pedal powered charger would fit perfectly as we wouldn’t have to use the resource of grid electricity. Great idea!

    I didn’t even know that something like this existed until clicking on this page. It would be amazing.

    My husband has just bought a bike and loves to listen t his music. He’s going to start cycling to work in the new year and its a 40 mile round trip so he would make good use of this charger

    I hate cycling home late at night on days when my phone has ran out of battery so this would be a bit of a life-saver and make me feel a lot safer 🙂

    I cycle to work, and work in a hotel. My manager is so miserable that she wont let me charge my phone at work. This would help

    This would be awesome for those long rides – particularly when in the middle of nowhere; love fact that it is charged by peddle power 🙂

    We are opening a bike cafe in Norwich in 2014. We’d love to have this charger for our customers to come in and use. We plan to have a few seats hooked up to pedal driven dynamos, so people can pedal while they have a coffee. Up to now we were just thinking of the dynamos lighting up table lamps, but charging a smartphone or tablet would be awesome! Cake-powered phones, how sustainable is that!

    It’s very nice in gathering of energy to charge my phone no need of house electric current. It’s very perfect.

    This device is exactly what we as a family were looking for, my son who is 11 sometimes gets so engrossed with looking up things on the iPad that he misses out on physical activity, we would use the charger on our exercise bike to remind him that if he wants to use the iPad he needs to stay active to get it charged up!
