The average American household has up to 40 devices plugged it and drawing power at any given time, which drives monthly energy costs up. The Belkin Conserve Socket is timed to turn your devices off when they're not in use. This power timer works best with small items such as irons, lamps, space heaters, cell phones, and laptops. It utilizes a switch to offer three different timer settings (30 minutes, 3 hours, 6 hours) and an automatic shut-off feature. The green LED indicator light will turn on when the socket is active and draws zero power until it is activated.The item is backed by a one-year limited warranty.
