Are car chargers bad for phone batteries?

Car phone holder chargers are not harmful to cell phone batteries. A car phone hold charger is an accessory for car owners to use car power supply to charge digital products anytime and anywhere. Some high-end car chargers generally include two USB ports, which can charge two digital products at the same time. Such products generally have four safety protection functions of overload protection, short circuit protection, high voltage input protection, and high temperature protection to ensure that the mobile phone can be used safely.

A car phone holder charger greatly solves the problem of car owners and passengers charging their mobile phones anytime and anywhere in a car to prevent the mobile phone from running out of power, but many car owners find the same problem, that is, when the car is driving on a flat road or uphill, the accelerator is slightly larger. It will cause a car phone holder charger to burn out or the mobile phone to shut down. In fact, this is caused by the lack of safety protection functions of inferior car chargers.

It is recommended to use the car inverter to increase to 220 volts, and then use the original or high-end charger to charge, so that it is safe for the mobile phone battery. In the place where the car is plugged into the car, the output voltage is between 12v-24v.
