Wireless charging A mobile power bank source is a device and a device with a built-in battery that can be charged wirelessly by obtaining electricity through wireless induction.Wireless charging technology is derived from wireless power transmission technology.Its working principle uses the principle of induction cooker.When an electric current flows through the coil, a magnetic field is created.The resulting magnetic field generates a voltage, which generates a current.When you have the current, you can charge it, and this technology is now used in wireless charging mobile power supplies.

    The principle of wireless charging mobile power source is to convert magnetic energy into electric energy according to the principle of induction cooker.

    Since wireless charging requires both sending and receiving terminals, wireless charging mobile power supply is equipped with sending device on the basis of traditional mobile power supply, and the mobile phone being charged supports wireless charging and has a receiving coil for wireless charging.In the case of the transmitter and receiver coils, the transmitter coils are connected to a wired power supply to generate an electromagnetic signal, and the receiver coils sense the electromagnetic signal at the transmitter to generate an electric current to charge the battery.

    What are the advantages and disadvantages of wireless charging mobile power supply?

    The advantages of wireless charging mobile power supply are convenient interactive data, fast transmission speed, simple operation, multi-function combined into one, which greatly facilitates our life. The disadvantage of wireless charging mobile power supply is also obvious, that is, it can only be charged from a close distance.
