A wireless charger is a device that uses the principle of electromagnetic induction for charging. Its principle is similar to that of a transformer. By placing a coil at the transmitting and receiving ends, the transmitting end coil sends an electromagnetic signal to the outside under the action of electric power, and the receiving end coil receives the electromagnetic signal. Signal and convert electromagnetic signal into electric current, so as to achieve the purpose of wireless charging. Wireless charging technology is a special way of power supply. It does not require a power cord, relies on electromagnetic wave propagation, and then converts electromagnetic wave energy into electrical energy, and finally realizes wireless charging.The use of wireless chargers is simple and convenient, allowing users to experience the surprise of new technology. It is a trend for wireless chargers to replace traditional mobile phone chargers. The specific advantages of wireless chargers include: (1) Convenience. There is no need to connect with a wire when charging, just put it near the charger. In the case of multiple electrical devices, multiple chargers can be saved, multiple power sockets are not occupied, and multiple wires are not entangled with each other; (2) Safety. No energized contact design can avoid the risk of electric shock; (3) Durable. Because the power transmission element is not exposed, it will not be corroded by moisture, oxygen, etc. in the air, and there will be no loss caused by mechanical wear and flashover during connection and separation. (4) The wireless charger can reduce the problems caused by the data line, so that users no longer need to be troubled by the knotting of the data line.We are a manufacturer integrating R&D, design, production and sales, specializing in the production of car chargers, mobile phone chargers and other 3C digital accessories.
