Car charging tips that car owners must know

one
Believe that if there is a USB interface for cars, there is no need for a car charger

Many people can't understand why there is already an excuse for USB in the car, can't it just be plugged in and charged? absolutely wrong. Because the vast majority of USB interfaces in cars are designed for audio data transmission, the interface current of most vehicles is only 5V/0.5A. If the current does not meet the standard at this time, it will damage the equipment.

two
Misunderstanding of charging current 'can be large but not small'

What does this mean? Simply put, the output current of the car charger cannot exceed the maximum rated input power of the mobile phone.

For example, if a car charger with an output of 5v/2.1 is used to charge a mobile phone with a maximum rated input power of 5V/1A, the car charger will input 1A to the phone and 2A to the tablet, which can fully charge the phone in a shorter time. However, if a car charger with an output current of 5V/0.5A is used to charge the same mobile phone, the input will be 0.5A, which not only takes longer, but also causes severe overheating and long-term damage to the phone battery.

After understanding this, you need to purchase a car charger with sufficient output and high quality. Don't spend thousands of yuan just for one car charger, it's not worth it.

There are too many USB ports, so charging is slow

The current depends on the voltage, not on how many USB interfaces there are. Just know this and don't be silly anymore. However, it is necessary to remind you to buy a legitimate car charger. Nowadays, the automotive aftermarket is mixed with good and bad products, and there are also many merchants who are greedy for money and do not pay attention to product quality. They will sell low current cars as high current outputs. If you unfortunately buy them, throw them away quickly. How do you know if it meets the standard? You can check the charging speed to see if the electronic product is very hot, and if so, it's a sign that the current is not up to standard.
