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!

The AT&T Zero Charger automatically senses when a mobile phone is not plugged up to the charger and it cuts the power supply from the wall socket. Other devices, including TVs, computers, and all kinds of home appliances, also draw power from the power grid when they are plugged in even if they aren't turned on. The U.S. Department of Energy estimates that standby power makes up as much as 20 percent of home energy use in the U.S.

The amount of power that is consumed by individual phone chargers plugged into the wall is small. But when you add it up over a long period of time, it can be significant. For example, AT&T estimates that if 80 percent of the wireless subscribers left their cell phone chargers plugged into a wall for a year, their phones would draw enough electricity to power 24,000 homes for a year, or brew 3 to 4 million cups of coffee each day.
