What is the difference between wired car charger and wireless car charger?

First: the charging method is different.

The wired car charger is connected to the USB port of the car charger through the charging line of the mobile phone for charging; the wireless car charger needs to first put a magnetic sheet on the back of the mobile phone, and then place the mobile phone on the wireless car charger, through the principle of wireless electromagnetic induction.

Second: 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. Ignore the problem that the phone only supports wired fast charge but does not support wireless fast charge, and ignores whether the wired charger and the wireless charger power are the same. In contrast, wired charging is more efficient than wireless charging, and wireless charging requires further improvement in technology.

Third: convenience.

Because the wireless car charger can be used both for charging and as a car holder, you can use the one-handed button to directly answer the speakerphone or pick up the phone with one hand to talk. After using the phone, you only need to put the phone on the sensor. It can be charged. For wired charging, you need to unplug the data cable. To connect the charger, you need to plug in the data cable again.
