How many W car charger is better

Because the car charger is convenient and reasonable, in the car application is very strong, so it is widely loved by many car friends, but at the same time there are many car friends in the choice of car charger W number made difficult, it is not clear how much power the car charger. I strongly recommend that you choose 9V-2A (18W) charger, if there are fast charging requirements can also choose a higher power car charger.

First, the car charger should not be too high or too low. The higher the power of the AC output of the car charger is more easy to electronic equipment or car supplies attached to household appliances caused by damage or burn, harm the car cigarette lighter and even damage to the car battery, the power is too low charger is likely not to meet the requirements of car friends, so should choose suitable power charger.

Huawei 40W car intercept fast charging is not the injury of the car, because the car charger work caused by the working current but several hundred mAh, for the car battery is just fur, as long as the conventional application of car charger, most of it is impossible to have what damage.

There are many current car chargers are embedded fuse tube, when the working current is higher than the overvoltage protection power circuit can bear the category, fuse tube will be fully automatic broken to maintain the power circuit, so car friends do not need to worry too much.
