Yes, the iPhone can be charged using a car charger. When you are driving in the car, the on-board charger will convert electricity from the vehicle's power supply into electricity in the phone's battery, thus providing continuous power to your iPhone. However, please note that the appropriate voltage and current should be selected when using the car charger to avoid damage to the phone or overheating of the battery. It is recommended to use an original or certified car charger to ensure safety and charging effect, and avoid using defective chargers.
