What is wireless charging?

Mobile phone wireless charging refers to the meaning that the charger and the electrical device can be connected to the phone without wires.

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 device that uses electricity. If the distance between the charger and the electrical device is far, it is necessary to use resonant inductive coupling design.

Wireless charging, 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 time for its own operation.

Wireless charging refers to the technology that provides electrical energy to 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 has gradually failed to meet the needs of users due to its problems such as inconvenient insertion and removal and limited device location. The emergence of wireless charging technology has solved these problems.

Wireless charging refers to the charger on the terminal device that needs to be charged without the traditional charging power cord, using the latest wireless charging technology, through the use of the magnetic field generated between the coils, the magic transmission of electrical energy, inductive coupling technology will becomeSome high-tech companies.

Does anyone use wireless power bank, is it easy to use, yes

1, wireless charging treasure will be more convenient than ordinary charging treasure, just put the mobile phone close to the wireless charging treasure induction board can be charged. Wireless charging treasure will be more easy to use, here by the way to recommend a few more easy to use wireless charging brand.

2, flexible charging: Although the wireless charging treasure is wireless, it often supports wired charging, which kind to chooseAll very convenient. And it can be used with multiple devices. Disadvantages: slightly slower charging speed: compared with wired charging banks, even with fast charging, the charging speed of wireless charging banks will be slightly slower, especially for devices with large-capacity batteries, and the charging time is longer. 3, although the wireless charging bank is more convenient when charging the mobile phone, we only need to put the mobile phone on the charging board, which can not only effectively avoid people when going out with more charger data lines and so on.

4, easy to use. The Apple wireless charging bank is sold on Taobao in order to be more convenientEasy to charge the phone, no longer use the line connection, saves a lot of trouble, so it is very useful. Wireless mobile power refers to devices and devices with built-in batteries that obtain power through wireless induction for charging.
