Are Car Chargers Harmful to Phone Batteries?

[Rebecca]

Car chargers can be harmful to phone batteries and may affect their lifespan. Here are the relevant details: 1. Voltage differences: Phone chargers require different voltages. For example, Apple phones typically use 5V1A, while other brands may use 5V2A. If a car charger is not labeled, it may provide 6V or 12V, which are different from the required voltage. 2. Battery capacity loss: Prolonged use can easily lead to battery capacity loss, meaning the battery won't hold a charge as well. Car chargers are mainly intended for emergency charging of electronic devices like phones, and should be unplugged promptly after use. If the car charger's voltage is abnormal, repeated charging can also impact the car battery.
