Q: Charging issue on iPhone 6

Hello jsm8,

Thank you for using Apple Support Communities. 

I see that you are getting an error that the charger isn't identified or supported. The following article addresses charging issues for the iPhone, including the one you describe. 

Charge your iPhone, iPad, and iPod touch

Specifically this section:

If an alert says that your accessory isn't supported or certified

These alerts can appear for a few reasons: Your iOS device might have a dirty or damaged charging port, your charging accessory is defective, damaged, or non Apple-certified, or your USB charger isn't designed to charge devices.

Follow these steps:

1. Remove any debris from the charging port on the bottom of your device.
2. Restart your iOS device.
3. Try a different USB cable or charger.
4. Make sure that you have the latest version of iOS.
5. Contact Apple Support to set up service.

Best regards.
