I have the new Droid3 and it charges just fine in the house. It will not, however, charge in my car using the charger that connects to the cigarette lighter. I have tried several chargers with no luck. It shows the charging lightening bolt but does not charge. Is there any special charger that I need to purchase. The chargers that I have work just find with the Droid Pro in the same car. The car is a 2002 PT Cruiser.
