When the wireless charger is used, it is necessary to connect the charger with the power supply, and plug the power supply into the socket. Then place the wireless charger on the back cover of the phone or other device until the phone or other device shows that it is charging. It should be noted that the wireless charger needs to maintain a certain distance from the device, and do not move the device when charging, so as not to affect the charging effect. In addition, during the use of the charger, if there is an abnormal situation, should stop the use and contact the after-sales treatment in time.
