    Just wondering if anyone else has tried using a USB adapter in their car without success, it could be the adapter I bought.

    The Droid will wake up when I plug it in but no charging happens.

    I think I had this happen too, but I attributed it to my adapter being broken, but I know it used to work with my iphone.....strange.

    I bought 3 adapters. 1 I put on my home wall charger, works fine. One I put on my cars charger, works fine. The 3rd Im using on a wall charger I have for work and I dont see it charging. Do I still get the charging icon if the battery is 100%?

    I have a universal charger that works fine with my Storm, iPod and my wifes Omnia. When I plug in the Droid it shows it's charging but doesn't actually charge it. It helps keep it alive but does not charge like it should.

    I checked out the power supply the Droid comes with and it puts out 700ma whereas most chargers go to 500ma.

    I think the Droid wants more power than some of these things put out.

    Well this USB adapter claims to be able to put out 5V at 2A, so power should not be the problem. It also charges my iPod no problem.

    I sense a conspiracy to make me buy the Verizon branded charger.

    wow

    Just a heads up, most PC motherboards only consider giving 1amp out the REAR ports, and only one amp to all front ports, if you have two front ports, then each gets .5 amps. =) Also please note motorola has always had a "conspiracy" where you need to buy one of their authorized chargers/install pc drivers. That was there way of ensuring the right voltage/amps to your phone. Good luck charging!

    No it will look like a full battery charge without the icon at 100%

    My new one doesn't charge with the car charger. The one I had yesterday did. What a shock :icon_cussing:


    My BB charges fine with the same charger.

    Motorola failed miserably rolling out this product.

    Yep I have the same problem. I think that it may have something to do with how the 'approved' chargers are wired. If you look at the forums for a DIY project called mintiboost they do some things to make their charger appear to the device. I dont know if that helps, but its my guess right now.

    Try This

    1. Plug the wallwart portion of the charger into the electric socket or cigarette lighter first.
    2. Plug the micro-usb end of the cable into the droid
    3. ONLY THEN plug the normal-usb end of the cable into the charger.

    I bought a set of chargers, one home and one car that didnt think worked untill I stumbled on this. Reply back if this works for anyone else.

    It seems that it needs reference voltages on the other 2 data pins, just like the Apple products.

    I've been looking into the required voltages. Hopefully I can make a small USB thing that goes between the USB output and cable.
