Have you ever wondered if charging your mobile phone in the car can damage your car battery? In this article, we delve into the truth behind this popular rumour.

Your car has a 12V socket for a reason. It doesn’t take a lot of amperage to charge a mobile phone, so it shouldn’t have an adverse effect on the car battery. The amount of electrical power required to charge a mobile phone is relatively low, so there is no need to worry about damaging the car battery. 

So, All’s Good Then?

That being said, it is important to exercise caution regarding the mobile phone battery itself, as the electrical power from the car battery may not always be stable. 

So whilst your car’s electrical circuit may be able to take the load of a phone that needs some power, your device itself may be susceptible to damage from fluctuations in the electrical current. 

To ensure a safe charging experience, here are some precautions to keep in mind:

• Always use standard charger cables to prioritise safety for yourself and your property.
• Start the car before plugging in the mobile charger. Avoid leaving the charger cable plugged in before starting the car, as the electrical current during car start-up may pose a risk to the phone's internal circuitry.
• Before turning off the car's engine, remove the phone from wireless chargers or unplug the charger cable.
