Just in case you haven't checked this simple option, are you sure it is charging (orange light & battery indicator with lightening bolt remain) during the ENTIRE time? I bought a "The Phone House" (French telecom accessories & phone store) brand micro USB car adapter that came with a standard PC USB to micro USB cord. Depending on the tilt of the micro USB within my HTC Desire (I tested it by using the cord alone in the HTC wall adapter after I couldn't figure out why it wouldn't charge with the car adapter it came with), it either lights up and work or doesn't. I periodically check to see if it is still connected properly (as a slight change in position can terminate the connection) and as long as it remains properly positioned, it works (and I periodically disconnected it to see if the battery indicator on the phone advanced (green battery indicator fills up).
Now I'll try the same thing in the car! I now this means the cord isn't reliable, but at least for now I have a backup cord. What I really wanted was the USB PC car adapter without a cord, so that was extra for me. Hope this can help someone.
I have a question though, does anyone know where I could find a micro USB tip that I can connect to a solar dynamo charger? I bought my charger before iPhone and HTC existed and though I have LG, NOKIA, etc, tips, I now need a micro USB 5-pin tip. Thanks in advance for any help!
