Answer to: iPhone says "This accessory may not be supported"Hello, experienced the same problem for a month until I finally decided to take a push pin...Yes, a push pin and very carefully inserted it into my phones charging port and to my surprise..out came a lot of pocket lint from carrying it in my pocket!! Very easy process of just "picking" out the lint which was not allowing my charger to fully insert and make a proper connection. After doing this, my charger fit snuggly into the port and just like that...CHARGING AGAIN!! Try this simple, inexpensive fix and you all may be pleasantly surprised!!
