The iPhone 15 can be charged via an in-car charger. First, you need to prepare a USB-C car charger, and then plug the charger into the 12V power port of the car. Then, connect the Apple 15's USB-C charging cable to the USB-C port of the charger to start charging. It should be noted that the output voltage and current of the car charger need to meet the charging needs of the Apple 15, and generally the output power needs to be 30W and above. In addition, when using the car charger to charge, it is recommended not to use the mobile phone during the vehicle, so as not to affect the safety of driving.
