Car charger is commonly used for car battery (car 12V, truck 24V) power supply car charger, widely used in a variety of portable, handheld equipment lithium battery charging field, but also to take into account the harsh environment of the car battery (transient peak voltage, system switching noise interference, EMI, etc.), so the power management IC selected by the car charger program must be met at the same time. High voltage resistance, high efficiency, high reliability, low frequency (conducive to EMI design) switching power supply chip.

The car charger is an accessory for the convenience of the owner to charge digital products anytime and anywhere with the car power supply. Some high-end car chargers generally include 2 USB interfaces, which can charge two digital products at the same time. 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, but also home, to achieve car charging, direct charging, USB charging three-in-one multi-functional use.

The principle of the car charger is to charge the mobile phone after the voltage of 12 volts is reduced to 5 volts, due to the price limit of the charger, the circuit has many defects, the protection function of the circuit is almost no, if the buck and current limiting circuit fails, it will lead to 12 volts directly into the mobile phone, the mobile phone will die.

Use the car inverter up to 220 volts, and then use the original charger to charge, which is safe for the phone battery. Where the car charger is inserted above the car, the output voltage is DC point, which is the voltage between 12v and 24v. If the quality of the car charger is not very poor, it will not affect the charging of the phone, but it is recommended not to use it often
