Does the commonly used car charger affect the mobile phone?


The car charger greatly solves the trouble of car owners and passengers charging their mobile phones anytime and anywhere in the car to prevent the mobile phone from running out. However, many car owners find the same problem, that is, when the car is driving on a flat road or uphill, the accelerator will be slightly larger It will cause the car charger to burn out or the phone to shut down. In fact, this is caused by the inferior car charger without safety protection function.


The car charger must be purchased from a regular factory, and the quality is guaranteed. It has overload protection, short circuit protection, high voltage input protection, high temperature protection, and four-fold safety protection to ensure safe use. I dare not say some miscellaneous names.

The principle of the car charger is to convert the voltage of 12 volts to 5 volts and then charge the mobile phone. Due to the price limit of the car charger, the circuit design has many defects, and the circuit protection function is almost lacking, such as voltage reduction and current limit during operation. Failure will cause 12 volts to directly enter the mobile phone, and the mobile phone will undoubtedly die.


It is still recommended to use a car inverter to increase to 220 volts, and then use the original or high-end charger to charge, which is safe and good for the mobile phone battery. Where the car charger is plugged into the car, the output voltage is between 12v-24v. Car chargers of well-known brands will not affect mobile phone charging.
