AT&T ZERO Charger Kills Vampire Drain When Your Phone Is Unplugged - HotHardware:

"The AT&T ZERO charger will become available in company stores starting this May, and the unique thing about it is that it will stop utilizing energy (often called energy leaks or vampire power) whenever your phone is unplugged. It intelligently shuts itself down when it's not being used to power a device, and while you probably won't notice a great deal of savings on your power bill, these could really make a dent in energy waste if everyone were to use one."
