charging mobile phones

  1. heres a curly one...
    would a motorcycle battery/charging system/alternater have enough power to charge my mobile phone while im riding?
    i do long trips, without any access to any power, so i figured i would just wire in a cigarette lighter socket and use my car phone charger....
    my bike sits in the high rev range normally round 10,000 rpm, (100kms hr) :?:



    thanks in advance.... :)

  3. Yes. You fill find that most mobile phones only require a constant 5v to charge, so a modified cigarette mobile phone adaptor will work, alternitavely, wire up a 12v line with a cigarette lighter socket on it, about $3 from DSE.

    Make sure you fuse it with a 5 or 10amp fuse on the +ve terminal!

    If you are unsure about electronics, always check before playing with wires and electricity because you may cause the smoke to get out..... (which is BAD!)

  4. Bunnings have a wind up torch with a mobile phone connection (Nokia, & a couple of others) No batteries.

    1 minutes winding gives you 25 minutes torch use or 2 minutes phone use.
    You can keep winding while you speak for continuous use.

    Cost is about $39. Good for carrying on the bike for emergencies.

  5. i saw this solar panel thing u can buy that uses the sun to charge up your phone battery
    the solar panels do have a sucky things on the bottom so it will stick to most things flat...
    not sure if that was any help though :roll: lol

  7. Stick a fused ciggie lighter socket under the bike somewhere and use the 12v charger you get with most phones.

    Those solar panels work well at keeping a battery topped up on a vehicle not being used often.

    As an example, if your car/bike is only used on weekends and is in a garage or carport that gets sun light all you have to do is connect the panel to the battery and it trickle charges the battery while it's sitting there (just make sure the panel is facing the sun for obvious reasons).

    These panels start around $40 so it's cheap insurance to keep the battery alive.

    A mates got on that sits on the parcel shelf of his "race car" (a 2lt Escort he plays with occasionally) and it has kept the battery alive a lot longer than just leaving it to self discharge over time.

  8. we have that ciggie lighter type of thing on the VTR, we even pumped up our air mattress with it when camping. its fine.

  9. Mobile phone chargers draw ~2 watts typically. At 10,000rpm, I'd guess your alternator would be pumping out somewhere between 150 and 200 watts, so 2 watts wouldn't make any real world difference whatsoever.

    Go for it.

  10. yep, my bike come standard with a 12v ciggie socket, so they can obviously handle it.

  14. Sorry, already done at least once :LOL: I know of a K series BMW (of course) with a small 12 volt fridge mounted as a top box. It's one of the small ones from Kmart. The guy who did it is a diabetic and needs it to keep his insulin cool.

  15. This is being a bit nit picky,.. but with the bugs in modern electronics, I
    would make sure that anything I add to the bikes circuit doesn't introduce
    any ripple on the rail.

    I would say that any power supply (cigarette lighter adaptor) that
    has been designed for a car would be no problem at all in a bike.

    ..But, just be mindful of what you add and if it has been tested
    for EMI and RF emissions.

  18. Errr sorry to drag up an old thread (nearly 1 year old!). :oops: Hey at least you know the search function works! :p


    I'm in the process of making up a removable cigarette lighter plug socket harness thingo.

    What i have is a cigarette lighter socket on a long spring type cord with an inline fuse and a + / - plug on the end that i put on.

    The idea is to install the other side of the connecting + / - plug to the bike so i can just plug and unplug as needed without leaving the bulky lighter socket hanging off the bike somewhere.

    What i want to know is instead of connecting the + / - of the other half of the plug straight to the battery can i wire it into the loom somewhere for example the headlight wires?

    This way it will turn off and stop charging and stop draining my battery when the bike is switched off if i forget to remove the charging device.

    Cheers
