Thanks for the reply's everyone.

I already have a few nokia micro usb car chargers.
2 work, 1 does sometimes and not others.

I wanted the usb so i could charge other items too, just throwing the cables in the armrest.
Various phones, headsets and anything else you can plug into a usb plug.

I'm going to try and find that post where you modify the usb outets, i'll see if i feel comfort with it.

Paul, you really feel that motorola charges faster?
I notice the phone takes longer on my nokia chargers, i guess that could be an option too.

Thanks.
