This transmitter DOES charge my iPhone 5 while transmitting clearly (need the apple lightning to 30 pin adapter). I find this transmitter easy to find a clear channel and strong enough to hold on to it, in both city and hwy driving, this is the best signal I have ever come across in a transmitter.
My only complaint is the lifetime of the product as the wiring seems to get shorted out or broken after a year or two, I'm on my 3rd one and the quality of construction doesn't seem to be improving. However I like this transmitter so much that I keep going for the same one.

This transmitter will play songs from your iPhone 5 via the 3.5mm or the 30pin w/ apple adapter but does not charge! FYI
