AT&T has introduced eco-friendly charger for mobile phone that eliminates 100 percent “Vampire draw”. According to AT&T, 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 new AT&T ZERO charger outperforms other chargers by automatically shutting down when not in use. Vampire draw is 100 percent eliminated and you’ll never have to unplug your charger again. The ZERO charger is USB compatible making it convenient to uses with various mobile devices supporting charging via USB.

AT&T says, “In the US, the total amount of electricity that flows through internal and external power adapters is nearly 470 billion kWh per year or about 12 percent of the nation’s annual electricity consumption. During the process these devices consume about 120 billion kWh per year of electricity and turn it into heat, costing the nation over $12 billion in electric bills”

AT&T hasn’t give release date or price for the ZERO charger, but you can sign up on AT&T’s website to get email alert as soon as the Zero Charger is available.
