Performance after time.

I used this on a few different vehicle with aux output. Has a slight noticeable whining noise when plugged. After a month or two of usage, I get a message in my iPhone 6s plus(a few months old brand new phone), I get a message that won’t let me charge my phone. With aux plugged in or not, doesn’t matter. I went with this, a bit more $ but I was hoping it would perform better. Not so happy as to when I first got it.
