So is there a difference in speed between the two I have seen that my car charger may be a little quicker charging my phone.
Wirelessly posted (Walkguru's: Mozilla/4.0 (compatible; MSIE 6.0; Windows 98; PalmSource/Palm-D062; Blazer/4.5) 16;320x320) my thoughts are the car charger is quicker. I usually use the home charger.
It all depends on what kind of home charger you have. Home chargers are often "trickle" chargers outputting 3.7 volts while quick chargers are usually 5.7 volts and will charge faster. 5.7 volt chargers did not work with earlier handsets. On your home charger it probably says what the output voltage is. It may say that on the car charger as well though not always. A trickle charger though is probably "kinder" to the phone.
