A:AnswerNo. All it does is charge the battery pack case which in turn only charges your phone. If you want car play you'll have to plug into the case itself even if it's on the vent mount.
A:AnswerI would not recommended this product for use with the iPhone X without a mophie case. It will not hold the phone to the charger without the Mophie case. The phone will slide off of the charger.
