AT&T’s ZERO draw charger will turn itself off when it isn’t actively charging. That is all.

It’s the eco-friendly charging solution for your mobile phone. Conventional chargers left plugged in – even when not actively charging – can draw as much as 5 to 20 times more energy than stored in the battery. The advanced, energy-saving AT&T ZERO Charger outperforms other chargers by automatically shutting down when not in use. “Vampire draw” is 100% eliminated and you’ll never have to unplug your charger again! Plus, USB compatibility makes the AT&T ZERO Charger a convenient charging station for many mobile devices!

You can give them your email address. Why you would want to I don’t know. They should just put the product into every box that goes out the door.
