    G'day Everyone,

    I'm trying to make a phone charger for my bike. I'm doing a long ride in a few months and want to charge my phone along the way. Now I have attached a photo of the setup. It consists of:

    A battery charging plug coming off the battery

    A 12volt cigarette lighter with a battery charging plug on the end

    A USB plug that fits into the 12volt cigarette lighter socket, and

    A usb cable to my phone.

    Now I have tested the power at every stage aswell as complete and the testerd shows its all good. When I plug the phone in its not charging. I have run the bike to see if it required the bike to be running but it still didn't work.

    Am I missing something? Any help would be great.

    Cheers Ryno

    G'day,

    do you have anything else you could plug in? Ipod, gps, laptop  to see if that works. Are the wires connected to the battery the right way around ? Is the USB cable working OK ? I have the same set up, and it works. I'll be back in 10 mins. Just going to make sure. cool

    G'day,

    sorry about the delay. I mislaid the plug, I disconnected about a month ago. Yes it does charge without the bike running.

    Is it a chinese made lightning connector cable and a late model iPhone?

    There were batches of those made that only charge with certain Apple products due to Apple including anti-copy hardware in their OEM cables.

    It's a Samsung galaxy s4 active phone. Everything works in the car. It's got me stumped.

    G'day,

    you are missing something. Is the socket in your hand correctly wired ? Try this, disconnect everything and then reconnect.   As you say, it should work.

    Ok the cigarette lighter has power on the inside of the cylinder walls but not the middle brass looking ring inside or the bottom of the cylinder.

    The inside (walls) of your cigarette lighter power socket shouldn't have power? That part should be "earthed" The post down in the middle should have the power +12v or similar.
    Sounds to me like the connections to your battery are arse about?
    Cheers.

    Ok I'm using a battery charger connection. The piece with the fuse is going to the positive. So I don't know how it could be backward. Ill go and double check everything again.

    Use the continuity setting on your multimeter to check which wire goes to the center of the socket. This should go to the positive terminal of the battery. Also, before connecting check the other goes to the outer wall of the socket. Last thing before you connect is to check there is no continuity between the two as a short between them could lead to problems to your bike wiring or battery.

    if you do this you can wire it up with confidence everything is correct. I take these steps even if I am sure I know what goes where as a few minutes to double check can save a lot of wasted time and heartache.

    hope it works out.

    If I had of seen that earlier I would have just bought that. I guess the polarity must be backwards. The trickle charger doesnt show any dramas when I hook it up. I think I will have to cut anr rewire the cigarette socket itself, otherwise I will stuff up the trickle charger with the same connection shown in chrisos first picture.

    Looks good. I might get one too.

    How/where do you recommend fastening it to the phone when you're riding?

    I've always charged it while in the pub or at coffee shop but no reason why ya can't have the phone in ya jacket pocket charging while riding, the plug is in tight and won't come out.

    I've got a solo bag so mine will be in there, otherwise you would cable tie it to the bike and run the cable into your pocket? maybe invest in a leather phone pouch and attach that to the bike.
