Wireless charging base: refers to the charger that does not need to be connected to 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 electric energy, inductive coupling technology will become a bridge connecting the charging base station and equipment.

[Usage] : Just connect the USB cable and plug it into the socket. When the phone is out of power or about to be out of power, put the phone casually on the charger board, the charger and the phone will realize inductive connection and charge in an instant.

The wireless charging system mainly adopts the principle of electromagnetic induction, and realizes the energy transfer through the coil energy coupling.

After passing through the power management module, the output direct current is converted into high-frequency alternating current through the 2M active crystal oscillator inverter to supply the primary winding. By coupling the energy of the two inductors, the electrical output of the secondary coil is changed into direct current through the receiving conversion circuit to charge the battery.

The changing magnetic field will produce a changing electric field, and the changing electric field will produce a changing magnetic field, and its size is related to their rate of change, and the rate of change of the sine function is another sine function, so the electromagnetic wave can be propagated, and the generation of induced voltage is related to the change of magnetic flux, so the magnetic field inside the coil will produce induced voltage, thus completing the charging process.
Wireless charging base is a new charging method developed in recent years, charging only need to put the smooth surface of the wireless charging base upward, and close contact with the electrical smooth surface with wireless charging function, you can charge.
Wireless charging is a charging method that does not require a transmission cable to transmit electricity to the device like a traditional wired charger, but charges the device that needs to be charged by contacting the wireless charging base. Wireless charging is also known as inductive charging or non-contact inductive charging.
