Second, Huawei wireless charging, reverse wireless charging to open and use methods
< br >
Huawei forward wireless charging usage:
< br >
1, put the wireless charger on the horizontal surface, connect the power supply;
< br >
2. Place the mobile phone\/tablet that needs to be charged in the central position of the wireless charger;
< br >
3, put on a few seconds after there will be a \"drop\" sound, indicating the start of charging.
< br >
Tip: Do not place anything between the phone\/tablet and the wireless charger, if the phone and the charger are placed between the magnetic holder, magnetic cover or other objects, it may reduce the performance of the charger, or damage the magnetic object.

How to enable and use Huawei Reverse wireless charging:
< br >
1. Enter Settings > Battery, open the wireless reverse charging switch;
< br >
2. After the device that needs to be charged is turned on, place it in the center position on the back of the device that supports wireless charging;
< br >

Third, Huawei wireless charging principle
< br >
Wireless charging technology uses two physical phenomena, current magnetic effect and electromagnetic induction. Current magnetic effect means that an energized coil will produce a magnetic field, while electromagnetic induction means that an unenergized coil will generate an induced current in a changing magnetic field. Wireless charging base and wireless charging mobile phone (or tablet, headset) respectively have built-in coils. When the wireless charging base is powered on, alternating current flows along the coil of the charging base, resulting in a changing magnetic field, the direction of which is perpendicular to the coil plane. When the mobile phone (or tablet, headset) is close to the wireless charger, The phone's internal coil generates an induced current in the changing magnetic field to charge it.
