Disadvantages: charging is a bit slow, because wireless charging conversion will be lossy. A little hot. You can't play with your mobile phone happily while charging.
Wireless charger refers to a device that uses electromagnetic wave induction principle to charge, and the principle is similar to that of transformer. Both the sending end and the receiving end have coils, and the coil at the sending end is connected with a wired power supply to generate electromagnetic signals, and the coil at the receiving end induces the electromagnetic signals at the sending end to generate current to charge the battery, which has large radiation and low charging efficiency.
The difference between wireless charger and wired charger;
Difference 1. Charging method: The wireless charger first puts the iPhone into the charging protective case, then puts the protective case on the induction base, then connects the induction base to the power plug, and then plugs it in.
Difference 2: Connecting peripherals: iPhone connects peripherals in wireless charging mode, one is to take out the iPhone that is loaded into the charging protective sleeve, the other is to connect Mini USB, and finally Mini USB connects peripherals. When the iPhone is charging on the power converter, just take the USB out of the converter and connect the peripheral devices.
Difference 3: Convenience: When the mobile phone is charging, there is a call coming in, but it is not convenient to answer it under some specific circumstances. At this time, the convenience of wireless charger is reflected. Just pick up the charging case and move it to any place where users can easily answer the phone. If it is a wired charger, you need to unplug the data cable, and you need to plug in the data cable again to connect the charging. At this time, the wireless charger only needs to put the mobile phone on the sensor to charge.
Difference 4. Charging efficiency: Under the same charging time, the power of the commonly used wired battery charger is 93%, and that of the wireless charger is 88%. Obviously, there is still a gap in the charging efficiency of wireless chargers, and there is still room for further improvement in technology.
