The charging technology used by the wireless charger is electromagnetic induction, which needs to be matched with the induction coil built into the phone to charge. Therefore, only mobile phones that support wireless charging technology can be applied to wireless chargers, otherwise wireless chargers cannot charge them. At present, most mainstream mobile phone brands have begun to support wireless charging technology, but there are still some low-end or old mobile phones do not support wireless charging, so it is not suitable for wireless chargers. In addition, due to the different technical standards and specifications of different mobile phone brands for chargers, it will also cause the situation that the charger cannot match the mobile phone.
Because some mobile phones do not have wireless charging function.
Wireless charger 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, by using the alternating magnetic field generated between the coils, the transmission of electrical energy, inductive coupling technology will become a bridge connecting the charging base station and equipment. Wireless charging technology received 20 patents in 2007, multiple devices can use a charging base station, mobile phones, MP3 players, power tools and other power adapters will not exist wired charging.
Wireless charging is not available for all phones, but there are ways to get all phones to use wireless charging. The principle of wireless charging is to use the principle of electromagnetic sensation for wireless charging. How do they achieve it, just like a transformer, there is a coil at each end of the sending and receiving, the sending coil is connected to the wired power supply to generate an electromagnetic signal, and the receiving coil senses the electromagnetic signal at the sending end to generate current to the electrical equipment.

Now in the market, some mobile phones come with wireless charging power, there is no need to connect a receiving chip (receiving end)
