2.5 Car charging is fast charging. Car charger charging speed is very fast, is fast charging, not flash charging. Fast charge is high voltage fast charge, flash charge is low voltage fast charge. However, the temperature of the high voltage fast charge will be higher than that of the low voltage flash charge, but it will not be hot, and it will be fully charged in less than an hour.
1, the car charger has no automatic power off function, after the car is turned off, the charger is still working, if it has not been unplugged, and for a long time did not start the car, it may consume the power of the car battery, not only affects the service life of the vehicle battery, but also when the car is to be used, it will not fire.
2, the car charger does not belong to the original car, there will be some problems in the degree of adaptation of the vehicle, considering the long-term discharge of the car charger, and there will also be leakage phenomenon at the socket, so it may affect the safety of the car.
3, poor quality car charger there are many security risks, due to the insufficient protection function of the circuit, if the buck and current limiting circuit failure, may lead to 12V voltage directly into the mobile phone, harm the mobile phone products.
Overall, the impact of the car charger on the car is still relatively large, so pay attention to the choice of formal products and the correct use of the method.
