1, can not, excessive increase in voltage or increase the number of turns will burn the battery, because the more you turn the higher the voltage, I do not know whether your self-made charger is Qi program, if it is Qi, it is not possible, this must be close contact, you have to change to radio wave type, within five meters.
2, no harm to mobile phones. Wireless chargerWith the latest wireless charging technology, the inductive coupling technology will be the bridge between the charging base station and the device by using the alternating magnetic field generated between the coils to transmit power.
3, wireless charging will not accelerate battery aging, will not have radiation to the body. The principle of wireless charging is electromagnetic induction. The charging dock is like an iron core with some primary coils wrapped around it. Cell phones have secondary coils built into them. The primary coil is energized to generate electromagnetic induction, so that the secondary coil generates induction voltage, and generates induction current to charge the mobile phone after loading. So don't worry.
4, although the deviceThe technical content is high, but the economic cost of the equipment is high, and the maintenance cost is large. Because of the realization of long-distance high-power wireless magnetoelectric conversion, the energy consumption of the equipment is high. As the distance and power of wireless charging devices increase, the loss of idle work will be greater.
2, connect the charger with the wireless charging base, and then place the mobile phone or the mobile phone with the wireless charging rear shell wireless charging coil on the wireless charging base. If the mobile phone leather case is too thick or not the original charging leather case, it may affect the charging effect, it is recommended to takeTry charging after dropping the holster.
3, this article will for Xiangzhou wireless charging coil you introduce the whole process of millet 11 wireless charging, so that you can easily open the wireless charging mode. Check if your phone supports wireless charging First, open "Settings," go to "Battery and Performance," and look for the "Wireless charging" option. If you see it, it means that your Mi 11 has wireless charging superpowers! Choose Qi standard charger Secondly, choose a wireless charger that is in line with Qi standard.
4. Huawei p40 Wireless charging Method Huawei WirelessCharging only for some mobile phones have this feature, not all mobile phones have it. This section describes how to enable and operate Huawei p40 wireless charging. Turn on wireless charging First, tap on [Settings] on the desktop of your phone.
1, the basic principle of wireless charging is to convert the current into a magnetic field, which is transmitted through the air and converted into a current to be transmitted to the intelligent terminal. After charging the battery and passing through the power management module, the DC output is converted into high-frequency alternating current through the 2M active crystal oscillator inverter to supply the primary winding. tongAfter the two inductors coupling the energy, the output of the secondary coil is changed into direct current through the receiving conversion circuit to charge the battery.
2, the wireless charging source is installed inside a electromagnetic coil, after the power switch is turned on, the electromagnetic coil converts the power supply battery into a large amount of magnetic energy, and then uses a reverse coil (international standard brick QI coil) to receive this large amount of magnetic energy, convert it into electrical energy, through a metal output head, into our equipment reserve battery. Wireless charging Because electromagnetic transmission only needs to be transmitted in space, no medium is required, so wireless charging can be carried out.
3, the basic principle of wireless charging is to convert the current into a magnetic field, and the magnetic field is transmitted through the air and then converted into a current to be transmitted to the intelligent terminal. When the system works, the input end converts the AC mains into direct current through the full bridge rectifier circuit, or uses the 24V direct current end to supply power to the system directly. 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.
4, wireless charging system mainly uses the principle of electromagnetic induction. 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, and uses the latest wireless
