The USB EcoStrip 2.0 helps you conserve electricity by turning power-drawing devices off when you aren't at your computer. EcoStrip 2.0 is an energy saving smart power strip with surge protection.It acts as a normal power strip/surge protector for your computer and peripheral devices, with one important difference: when the computer is turned off, power is shut down to peripherals eliminating the drain of "vampire" electricity. According to the International Energy Agency, the U.S. spends almost $11 billion annually on electricity lost to "Vampire Power." A computer left on continuously uses 70 to 250 watts — nearly as much power as an energy efficient refrigerator.
