1. Bluetooth connection is not required.
2. Wireless charging treasure achieves charging through electromagnetic induction principle.
It has a transmitting coil and a receiving coil. When the wireless charging bank is in contact with the device supporting wireless charging, the transmitting coil will generate an electromagnetic field, and the receiving coil will sense the electromagnetic field and convert it into electrical energy, so as to achieve charging. 3. The charging principle of the wireless charging treasure is based on electromagnetic induction technology, and charging is realized through the transmission of electromagnetic fields, so there is no need to connect Bluetooth or other wireless communication methods.
The advantage of this charging method is that it is convenient and fast, there is no need to plug and remove the charging cable, and the device can be charged by simply placing it on the charging bank.
At the same time, the wireless charging bank can also be charged by connecting the power supply through the charging cable, so that it can be used without electromagnetic induction equipment.
The wireless charging treasure does not need to be connected to Bluetooth, and its charging principle is that its charging treasure shell can be charged at close range by current transmission
