First of all, you need to have an APPLE mobile phone that supports unlimited charging, such as iPhone X, iPhone8 plus, etc. Then you need to buy wireless chargers from formal channels, and it is recommended to buy them from Apple official dealers. Then power the wireless charger and plug it inMake sure there are no magnetic objects around before the source. Then place it in a flat place to prevent the phone from slipping off it.
