Why Is My Iphone Cable Not Supported. Updating to the latest iOS may fix the Accessory Not SupportedCertified issue. If your car USB port isnt charging your phone the problem could be with the port the cable or even the phone.

Their is a chip in the Lightning cable. Then plug in the charger. The Accessory is not Apple-approved.
Moreover it is recommended to plug your iPhone to the computers USB port rather than a USB port built into the keyboard USB hub.
If you are using a computers USB port you need to confirm that your computer is not shut down or in the sleep or hibernation status then change the USB port. Remember that dust and lint will not. Wait for 1-2 minutes and turn it on again with the accessory attached. Check the Charging Port.
