Why Does My Iphone Charger Say Not Supported. I bought a Mophie Juice Pack Air for my iPhone 5 back in April and under iOS 6 it gave me the warnign that it might not be supported but it still charged my iPhone 5. Works for me anyway.

Your iPhone software is malfunctioning. Then I inserted my Iphone back i the phone supportcharger and the message went away. So if possible use the original cables chargers and adapters that came with your iDevice.
Your accessory is defective damaged or not Apple-certified.
Your charger is dirty damaged or completely broken. Place iPhone Close to Wireless Charger or in the Center. A variety of different things could be causing the problem. Turn on Airplane Mode.
