I use the iGO Charger both in the car and at home.
www.igo.com . The tip required for the HTC Touch Pro is (A53). In my oppinion, this charger takes better care of the battery than the OEM that came with the phone. Before I got the Touch Pro, I had the 6700, and used the iGO with it for three years never having to replace the battery. Try for yourselves. I'm already sold, and will be using this charger for all future devices as well.
