Do car chargers affect phones?

March 29, 2023

Car charger is a must for every traveler, has become a lot of car owners often used equipment, so this time some people consider, car charger has an impact on mobile phone? Will it damage the phone? Let's follow the charger manufacturer to understand it!

Car charger is commonly used for car battery (car 12V, truck 24V) powered car charger, widely used in a variety of portable, handheld equipment lithium battery charging field, such as: mobile phone, PDA, GPS, etc.; Car charging should not only consider the actual demand of lithium battery charging (constant voltage CV, constant current CC, overvoltage protection OVP), but also take into account the harsh environment of vehicle battery (transient peak voltage, system switching noise interference, EMI, etc.); Therefore, the power management IC selected by the car charging scheme must meet the following requirements: high voltage resistance, high efficiency, high reliability, low frequency (conducive to the design of EMI) switching power chip; Popular speaking is the requirement of "real".

Car charger is an accessory for car owners to charge digital products anytime and anywhere with car power. Some high-end car chargers typically include two USB ports to charge two digital devices simultaneously. Such products generally have overload protection, short circuit protection, high voltage input protection, high temperature protection four safety protection functions to ensure safe use. Car charger in the car at the same time, also can be used for home, to achieve car charging, direct charging, USB charging three-in-one multifunctional use.

Can car charger damage your phone?

The principle of car charger is to reduce the voltage of 12 volts to 5 volts after charging the mobile phone, due to the price limit of the charger, there are many defects in the circuit, the protection function of the circuit is almost no, if the voltage reduction and current limiting circuit failure, it will lead to 12 volts directly into the mobile phone, the mobile phone will die. It is recommended to use the vehicle inverter to 220 volts, and then use the original charger to charge, so it is safe for the mobile phone battery. Where the car charger is plugged in, the output voltage is DC point, which is between 12v and 24v. Car charger quality is not very poor, it will not affect the phone charging, but it is recommended not to use often.
