1, wireless reverse charging refers to mobile phones and other devices that can only receive wireless charging electromagnetic waves, and can now emit electromagnetic waves through wireless coils to charge other devices that support wireless charging. However, its charging power is small and can only be used as an emergency.
2. The charging power of wireless reverse charging is not very large compared with the original charger of the mobile phone, and the speed of charging large-capacity devices will be slower in daily life, which is more suitable for emergency use in emergency situations.
3, need to support the receiving equipment that meets the QI wireless charging protocol, whether to support the QI protocol, it is recommended to consult the equipment manufacturer, such as: electric toothbrush, razor, mouse, headset, toys, accessories, etc.;
4. The receiving device is placed in the center of the back of the phone. Do not place metal materials such as bus passes and coins between the receiving device and the mobile phone. After the wireless reverse charging function of the phone is turned on, do not place the phone directly on the metal material.
Wireless charging is to charge other devices that support wireless charging by sending electromagnetic waves through the wireless coil; Low-power wireless charging is usually electromagnetic induction, high-power wireless charging is often resonant (most electric vehicles are charged in this way) by the power supply device (charger) to transmit energy to the power device, the device uses the received energy to charge the battery, and at the same time for its own operation.
