The difference between wired car charger and wireless car charger

1. Different charging methods

The wired car charger is connected to the USB port of the car charger through the mobile phone charging cable for charging; the wireless car charger needs to be attached with a magnetic sheet on the back of the mobile phone, and then the mobile phone is placed on the wireless car charger, and charged by the wireless electromagnetic induction principle. .

2. Charging efficiency.

Although wireless charging has become very popular with the launch of the iPhone X, there is still a gap in charging efficiency between wireless charging and wired charging. Although professional engineers test that wireless charging is not slower than wired charging, all of this can be achieved with the same equipment current, voltage, power, charging time and so on. Obviously, ordinary people will not pay attention to the problem that their mobile phones only support wired fast charging but do not support wireless fast charging. They will not care whether their wired chargers and wireless chargers have the same power. They only know that they are in use. Wired charging is much faster than wireless charging. Indeed, wired charging is more efficient than wireless charging in the context of large environments, and there is room for further improvement in wireless charging.

3. Convenience.

When you answer the phone while driving, the convenience of the wireless charger is reflected. Because the wireless car charger is both rechargeable and can be used as a car holder, after using the phone, you only need to place the phone on the sensor to charge it. For cable, you need to unplug the data cable. To connect the charger, you need to plug in the data cable again.

So, is there any need to replace the USB car with a wireless car charger?

This really depends on individual needs. Wireless car chargers and cable car chargers have their own advantages, and there is no absolute good or bad. If you use a mobile phone for navigation, it is recommended to use a wired car charger to charge, charging is faster. If it is just for normal use, it is recommended to use wireless car charger, because wireless can be used. One-handed operation, it can also be used as a car phone holder, safe and convenient!
