Okay so I've seen some threads asking about chargers but they seem to not answer my question 100% clearly. So here it is: Can I use my old LG Dare or Motorola Razr chargers? Both the car and wall adapters? I am well aware that the USB cable works, but is it safe to use either one to charge my Motorola Droid without harming the battery?? I cannot seem to easily find any documentation on this online and I would love to not have to purchase yet another car charger. Any proof would put my mind at ease because I really don't want to damage my incredible new phone. Thanks ahead!
