Wireless reverse charging refers to: the mobile phone as a wireless charging base, to support wireless charging devices (such as: watches, bracelets, mobile phones, etc.) to charge. Wireless reverse charging technology, derived from radio energy transmission technology, can be divided into low-power wireless charging and high-power wireless chargingTwo ways. Low-power wireless charging often uses electromagnetic induction, such as the Qi method of charging mobile phones, but ZTE's electric vehicle wireless charging method uses induction.
Wireless reverse charging means: The function of using the mobile phone as a mobile power to charge other devices, first connect the two mobile phones with the OTG line and the mobile phone data line, and then change the USB connection mode in the notification bar to reverse charging on the mobile phone at the power supply side. There is a premise here that the mobile phone at the power supply side supports OTG, and if the other mobile phone does not support reverse charging, the supported end will automatically supply power.
Wireless reverseCharging refers to the mobile phone and other devices that can only receive wireless charging electromagnetic waves, and now can emit electromagnetic waves through the wireless coil to charge other devices that support wireless charging. However, its charging power is small and can only be used as an emergency. The charging power of wireless reverse charging is not very large compared with the original charger of the mobile phone, and the speed of daily charging of large-capacity devices will be slower, which is more suitable for emergency use in emergency situations.
1. Take Huawei P40 Pro mobile phone as an example: Enable wireless reverse chargingSetting: Enter the phone to set the battery and turn on the wireless reverse charging switch. Warm reminder: Do not enable the wireless reverse charging function of the charged device. If the reverse charging function is enabled for two mobile phones at the same time, one mobile phone will randomly switch to the receiving end, which may cause abnormal charging. After the wireless reverse charging function of the mobile phone is enabled, do not place the mobile phone directly on the metal material.
2, to use wireless reverse charging, first make sure your device supports this feature. The technology is built into most new smartphones and tablets. Before using it, you need to enable wireless reverse in your device's Settings menuCharging options. Once enabled, you can place another device that supports wireless charging on the back of your device, ensuring alignment and close contact between the two. After the device is properly aligned, wireless reverse charging will automatically begin.
3, wireless reverse charging refers to: the mobile phone as a wireless charging base, to support wireless charging devices (such as: watches, bracelets, mobile phones, etc.) to charge. Wireless reverse charging technology, derived from radio energy transmission technology, can be divided into low-power wireless charging and high-power wireless charging two ways. Low-power wireless charging often uses electromagnetic induction, such as Q for mobile phone chargingi mode, but ZTE's electric vehicle wireless charging method uses inductive mode.
1, wireless charging is also known as inductive charging or non-contact inductive charging, based on the principle of electromagnetic induction, it is not necessary to transmit electricity to the device like the traditional wired charger, but the device that needs to be charged can be charged by contacting the wireless charging base.
2, wireless charging system mainly uses the principle of electromagnetic induction. Wireless charger refers to the need to charge without connecting the traditional charging power cordThe charger on the electric terminal equipment adopts the latest wireless charging technology, through the use of the magnetic field generated between the coils, the magic transmission of electrical energy, inductive coupling technology will become the bridge connecting the charging base station and the equipment.
3, wireless charging is achieved by electromagnetic induction technology. Specifically, the wireless charging device will generate an alternating magnetic field at the transmitting end, and when the receiving end (that is, the device that needs to be charged) enters this magnetic field range, the current will be induced inside it to achieve the charging function. Wireless charging technology mainly uses Faraday's law of electromagnetic induction.
4, first needMake sure the phone supports wireless charging, because wireless charging requires the hardware support of the wireless induction coil built into the phone. Connect the wireless charging board with the data cable to the charger, the general mobile phone charger can be used, the charging board will have a light prompt after the general connection, and then put the mobile phone on the charging board.
5, the way of wireless charging is electromagnetic induction, magnetic resonance, electric field coupling and radio wave transmission, etc., wireless charging of mobile phones mostly uses the principle of electromagnetic induction. Electromagnetic induction wireless charging, when the current of the power supply through the coil (wireless charger's power supply coil) will generate a magnetic field, the otherWhen an unenergized coil (the charged coil on the phone) is near this magnetic field, it generates an electric current, which charges the phone. As shown below.
6, finally realize wireless charging. Low-power wireless charging often uses electromagnetic induction, such as the Qi method of charging mobile phones, and ZTE's electric vehicle wireless charging uses induction mode. High-power wireless charging usually uses resonance (most electric vehicles are charged this way) to transfer energy from the power supply device (charger) to the electrical device. The device uses the received energy to charge the battery and at the same time provide energy for the battery's own operation.

Wireless reverse charging refers to the original mobile phone can only receive wireless charging electromagnetic wavesThe device can now emit electromagnetic waves through the wireless coil to charge other devices that support wireless charging. However, its charging power is small and can only be used as an emergency. Wireless charging technology (English: Wirelesschargingtechnology; Wirelesschargetechnology is derived from radio energy transmission technology, which can be divided into two ways: low-power wireless charging and high-power wireless charging.
Wireless reverse charging means that the mobile phone is used as a mobile power to charge other devices, and the OTG line is first added to the mobile phone data line
