Does charging a phone in the car affect the battery?

Charging a phone in the car has basically no impact on the battery. Here are specific details about charging a phone in the car: 1. Impact: Most USB ports in cars are designed for audio data transmission, so the current is only 5V/0.5A, which is not suitable for directly charging a phone. In fact, it may damage the device due to insufficient current. When charging a phone in the car, be careful not to use the car charger in a humid environment, keep it away from children, avoid lightning strikes, and unplug the charger promptly after charging. 2. Precautions: To avoid forgetting a power bank or running out of phone battery, it's best to keep a car charger in your vehicle. Although cars have USB ports, if the current is too low, it may damage the phone. Plug the car charger into the USB port to regulate the current, ensuring it remains stable and reduces damage to the phone. Simply plug the phone into the car charger, but remember to turn it off when getting in and out of the car.
