iphone 6 cable or accessory is not certified and phone will not charge?

Hello, jagfan2020.

Thank you for visiting Apple Support Communities.

I would need clarification on the issue that you are experiencing to provide a better answer. However, it sounds like you are not able to charge your iPhone with a Lightning cable that is not certified. You will need to use an Apple Certified Lightning cable in order to charge the device. If you are experiencing an issue charging your device, take a look at the troubleshooting article below.
