AT&T ZERO Charger Targets Vampire Cell Phone Plugs

AT&T Takes Aim At Vampire Cell Phone Plugs With ZERO ChargerWe've lectured you before about unplugging chargers to conserve electricity. It's pretty much common knowledge at this point that, even when turned off, our gadgets consume energy. Design student Conor Klein's solution was the Outlet Regulator, which detects when a cell phone is fully charged and then physically jettisons it from the power source.

AT&T has a less perfect, but slightly more practical fix: simply shut down the charger when nothing is connected to it. The ZERO Charger can tell when a gadget is connected to its USB port, and simply disconnects from the power source if nothing is plugged into it. It can't tell when your iPhone is completely charged and then turn itself off, but, if you're the type who can't be bothered to remember to unplug your charger when you leave the house, the ZERO charger could end up saving you a few bucks on your electricity bills.
