About the error message "This accessory may not be supported by device" : The message would appear if you were using an unsupported wall charger or in poor contact, but even if you are using an original iphone accessory, the error can also happen for the firmware problem with iOS. You can try the following solutions: · You can use a pushpin to clean out the pocket lint or debris from the charging port. · Wipe the Lightning end with a tissue to remove dirt and oxidation marks on the lightning end. · Use the original charger or MFi authorized charger, because some laptop USB output ports may have insufficient power output. · You can use a pushpin to clean out the pocket lint or debris from the charging port. · Wipe the Lightning end with a tissue to remove dirt and oxidation marks on the lightning end. · Use the original charger or MFi authorized charger, because some laptop USB output ports may have insufficient power output.
