AT&T has just announced a USB-based telephone charger that does not pull electricity from the wall when it's not charging a phone. I don't know about you, but my charger is plugged in 100% of the time. That charger pulls a tiny amount of energy from the wall 24 hours a day 365 days a year. Multipy that by 100 million chargers in America and there's probably at least one coal-fired power plant in America dedicated entirely to that wasted power.
AT&T's new charger, however, is a standardized USB charger that does not pull any power from the wall when there's nothing plugged into it. You wouldn't think this was a particularly complicated thing to do (especially since chargers routinely cost thirty FREAKING dollars.) But high-markup chargers are a big part of cell phone company's profit models, so they aren't generally interested in pulling R&D dollars from that big tasty pie.
But it works, and it will charge a variety of devices, even non-AT&T devices. It's great news for us all, and at the same cost as a regular (dramatically overpriced) cell phone charger.
Let's hope the technology makes its way into other vampire power culprits soon. Read the full press release from ATT here.
