About the error message "This accessory may not be supported by device":
The message would appear if you were using a non-Apple wall charger or in poor contact, but even if you are using an Apple accessory, the error can also happen for the firmware problem with iOS.
After analysis, the causes of this problem may be the following:
1.Device lightning port contains impurities such as fiber and debris, resulting in poor contact.
2.The lightning end is corroded/stained, resulting in poor contact.
3.Circuit logic problems/system problems with charging equipment.
4.The voltage of the wall charger is too low or unstable, resulting in insufficient power supply.
5.The chip or mainboard of the cable is damaged.
You can try the following solutions:
1.You can use a pushpin to clean out the pocket lint or debris from the charging port.
2.Wipe the Lightning end with a tissue to remove dirt and oxidation marks on the lightning end.
3.Use the original charger or MFi authorized charger, because some laptop USB output ports may have insufficient power output.
