1, mobile phone wireless charging refers to the charger and the electrical device between the two can charge the phone without wire connection. 2, wireless charging is also known as inductive charging, non-contact inductive charging, from wireless power transmission technology, is the use of near-field induction, that is, inductive coupling, by the power supply device (charger) to transmit energy to the power device, the device uses the received energy to charge the battery, and at the same timeFor its own operational purposes.
3, wireless charging, also known as inductive charging, non-contact inductive charging, is the use of near-field induction, that is, inductive coupling, by the power supply device (charger) to transmit energy to the power device. If the distance between the charger and the electrical device is far, it is necessary to use resonant inductive coupling design.
4, wireless charging refers to the technology of providing electrical energy for electronic devices through wireless technology. Wireless charging mainly relies on wireless induction technology to achieve energy transmission. With the rapid development of electronic technology, the traditional wired charging method is inconvenient to plug and unplug and restricts the equipmentProblems such as location gradually cannot meet the needs of users, and the emergence of wireless charging technology solves these problems.
Magnetic charging is through the magnet male and female suction, so that the charging cable and the jack can be connected to charge. In essence, it is still wired charging, but from plug-in to adsorption. This is very different from wireless charging, magnetic charging can not be without a cableCharge up. Wireless charging is a technology that does exist, and the technology has been widely used in electronic devices.
Magnetic charging refers to the charging method through the magnet male and female suction to achieve the charging effect. In essence, it is still wired charging, but from plug-in to adsorption. This is very different from wireless charging, magnetic charging can not be charged without a line. Magnetic charging transmission speed is fast, perfectly compatible with mobile phone data transmission.

Magnetic charging cable is also known as magnetic charging cable, magnetic charging cable, magnetic charging cable, magnetic charging cable, magnetic data cable, etc.
This is very different from wireless charging, magnetic charging can not be charged without a line. Compared with the ordinary wireless charger, the magnet induction can be accurately aligned to solve the possible displacement of the device when charging. Mobile phone charging is through wireless charging, magnetic wireless charging body or through wired power. However, there is a more obvious improvement in the convenience of charging.
1, the attraction of wireless charging is that it eliminates the hassle of plugging and unplugging cables, but it is not. In the case of the Pixel 4, wireless charging takes 201 watt-hours (Wh) to fully charge, while wired charging only takes 126 watt-hours. This means that wireless charging not only consumes more time, but also comes with additional heat generation and power waste. Even when the wireless charger is idle, the charger that is not aligned with the phone or around it can consume power.
2, battery loss: relative to wired charging, because of the wireless charging periodThe heat generated between will be relatively high, so wireless charging will actually lose slightly more battery. The distance is too small, just a transitional technology: because the magnetic field decays quickly in the air, the distance of wireless charging technology of current mobile phones is generally very small, and the effective charging distance is generally only 3-8 mm.
3, so when charging, in addition to the working elements inside the phone will heat up, the secondary coil of the wireless charger will also heat up.
4, wireless charging does not need to pull the power often. Wireless charger can be plugged into the power supply, the only disadvantage is that it will consume more power, and the life of the charger is also
