I bought a car kit off eBay the other day, basically just an in car holder and cigarette lighter charger, however with the phone switched on and using sat nav the phone uses power faster than it can charge, so after a 2 hour drive I only had 25% battery left from a full charge, anyone else had this problem? The phone even flashed up a warning telling me to plug in an AC charger.
you got a crappy ebay job.... some of those chargers are duff.. i brought two, one was 99p with free postage and done the same thing.... binned it! try play or the rain forest place... you have to be careful with some of this cheap generic stuff... mate had a usb cable that was fruity and could not root unless he used his default one...
