Misuse of Car Chargers

In this information age, mobile phones are indispensable equipment, no matter whether you are eating, traveling, or going to the toilet. So nowadays, most cars are equipped with car chargers that can be plugged in at any time. So how should we use the car charger correctly?

Misunderstandings about car chargers

USB in the car directly charges the mobile phone

Many cars have their USB interfaces, and there may be more than one interface. However, these USB interfaces are not set for charging mobile phones, but for audio data transmission. Therefore, the interface current of most cars is only 5V/0.5A. The charging current can be large or small. If you use the USB interface on your car to charge your mobile phone or even tablet, the device will be damaged if the current is not up to the standard.

The more USB interfaces, the slower the charging speed

The current depends on the voltage, not the number of USB interfaces because the current has been divided and does not interfere with each other. If it is slower than the charging of a single USB interface, who will buy it?

Be sure to unplug the car charger after stalling

Now, most of the car's cigarette lighters are already ACC instead of regular power, which means that the car can be powered off when it is turned off. This is a safe practice. Even if the car is powered off, generally speaking, the car charger has no current output when it is not connected to the load. Even if it is not unplugged, only small LED lights are working, and the battery power consumption can be ignored.

Don't pay attention to the maximum power of the expansion port

Many small tools in the car need to be powered by the cigarette lighter. So many people will buy a car charger with a cigarette lighter expansion port that is one driven by three. However, for the same product, people often say that it is easy to use. Some people say that the fuse is burned, which may be because the equipment exceeds the maximum power of the expansion port. Especially for the car refrigerator and car vacuum cleaner with high power, you must first see what the power is. See if the expansion port of your car charger can be used. Generally, it will be indicated on the packaging box or instructions.
