Car charger, this little gadget, is mainly used to power the driving recorder or to temporarily charge the mobile phone. As a worthless gadget on auto parts, few people have to worry about picking them. Some people even pick the cheapest ones, and they get it for ten yuan. However, it is such a small car charger, but many people are troubled. Why is this?
Can't charge the car charger, what to buy?
Although the car charger is not expensive, it is an indispensable accessory on the car, even when the phone is dead, it is a tool for "lifesaving". But if you buy a car to charge the phone at a critical moment, do you have the urge to swear?
In fact, this is not impossible. Many people buy a car charger and only pick a cheap one, but rarely really care about its quality. A careful person, just use a mobile phone line to connect, see the phone charging light lights up and think it's okay.

In order to avoid this embarrassing situation, we still try to choose a reliable and well-respected brand car charger.

In order to avoid the unstable voltage of the car charger, the best way is to choose to buy a car charger with voltage digital display function. This type of car charger not only displays the voltage at the time of charging, but also shows the different voltage changes before and after ignition of the vehicle. Many people will ignore whether the vehicle is on fire when charging the mobile phone. When the voltage of the car charger is low, it means that the vehicle is not activated, and the user can be reminded to avoid charging the mobile phone at this time.
The fire hazard is even more shocking
In addition to the problem of not charging power and voltage instability, there is still a hidden danger in inferior car chargers - burning and spontaneous combustion. This is not an alarmist. The Fujian Provincial Product Quality Inspection Institute has carried out product quality and safety risk monitoring for vehicle chargers. The results show that some car chargers have major safety hazards such as short circuit, fire and explosion.
Therefore, in order to reduce such risks, it is best to use a reliable and well-respected brand of car chargers.
It can be seen that inferior car chargers not only delay things, but also can damage the mobile phone, and even have the danger of spontaneous combustion. For the safety of themselves and their
