1. Whether the mobile phone model supports wireless charging OR whether the wireless charger matches

Wireless charger sometimes put up no response, first of all, depends on the mobile phone model support, do not need to install wireless charging coil.

a. Mobile phone built-in wireless charging receiver: it can be charged directly on the wireless charger.
< br >
b. Wireless charging receiver contact is reserved inside the mobile phone: wireless charging receiver coil needs to be installed to achieve wireless charging.
< br >
c. The mobile phone itself does not support wireless charging at all, and it is necessary to install a wireless charging receiving back frame to achieve wireless charging.

2. Whether the wireless charger indicator light is displayed normally

Secondly, some brands of wireless chargers have LED lights around, when the mobile phone is charged on the wireless charger, the LED lights around the wireless charger will light up, or some prompt tone, showing the use status. Sometimes it is slow, it takes a few seconds to charge, and sometimes it has to be replayed.

3, mobile phone protective shell and other external factors of wireless charger

Then, please check whether the back center of the mobile phone is placed in the center of the wireless charging board, and check whether there is inclusions between the mobile phone and the wireless charging board, it may not be able to charge normally; Check the back shell of the phone again. If the protective phone cover used is too thick, it may hinder wireless charging. It is recommended to remove the phone cover and try to charge it again.

Finally, the transmitter power of the wireless charger may also lead to the reason why wireless charging can not be used. The receiver output short-circuit current can reach 1A, the actual charging is only about 0.3, plug in the mobile phone voltage directly dropped to 3.9V, this voltage can not reach the rated voltage to charge the mobile phone, and the maximum working current of the wireless transmitter is only 600ma, smart phone charging needs more than 700ma~800ma. Therefore, the transmission power of the wireless charger is too small, and it will also make the charge not go in.
Check whether the center of the back of the phone is placed in the center of the wireless charging pad or whether there is debris between them. You can also use other mobile phones or wireless chargers to eliminate problems, the simplest is to go after sales maintenance.
After changing the number of turns, the output voltage will change, since it is the increase of the charger end, the receiving end is unchanged, then the output (receiving end) voltage will become smaller, may not be charged
