Q: No iPhone/iPad Charging with Car Charger

I have a 2015 Honda CRV.  All of a sudden, none of our iPhones will charge with the car chargers.  Two different chargers, two different ports, lights showing power to the cables on both, worked previously.  Our iPhones include a 6Plus, 6, and 5S.   I have rebooted my iPhone 6 with no results.  We travel a lot and this is a real inconvenience.  Any ideas?

Thank you,

Paulette
