iPhone 4S won't charge in wall charger will charge from PC USB

Suddenly, about a week ago, shortly after I upgraded to iOS 6.1.3 my iPhone 4S will no longer charge from any AC chargers, but still charges from the USB port in my laptops and work desktop.  I have 5 or 6 wall chargers both Apple and other brands it won’t charge from any of them.  They work fine charging my wife’s iPhone 4S and my iPad 2 and iPad 4.  I have seen others post about this problem but there are no fixes posted to date.
