One of the reasons I ask is that on my Motorola phone they warned to only use theor charger (yeah I know) or it could damage the phone. When I checked the specs on that it was a little different from a generic charger. Also my phone ran real hot the first day I got it but I think that was due to importing all my settings from google for the Motorola phone and the Sony reacted badly to that. A factory reset and no google restore cured that behavior. I've since used the charger without issues so I think all is well in car charger land now.
