Why Won't My iPhone Charge in the Car?

 USB-C to Lightning cable.

Episode 1640

Ann from Long Beach, California

Ann complains that her iPhone won't charge in her car anymore. She gets a message saying "accessory not supported." Rich suspects that the port in her mobile device could be a bit dirty and blowing it out could help improve the connection. But it could also be time to get a new cable. They do stop working after a while and that message usually indicates a degrading connection. For the fastest, go with a USB-C to Lightning cable.
