Save energy and lower your utility bills by up to $40 per year by eliminating phantom power loads—power wasted by devices when they aren't in use. A combination of always-on and power-saving outlets let you keep important devices constantly on while tying peripherals like printers and powered subwoofers to a master device. Unique wattage switch ensures reliable operation whether you're using a high-wattage master device (such as a television, desktop or full-size laptop computer) or a lower wattage master device (such as a netbook). Data line surge protection protects equipment connected to a phone or Ethernet network line, including modems, fax machines, routers and other communications equipment. Integrated child-safety outlet covers safely seal off unused outlets. Space-saving, right-angled plug provides easy plug in. 8 Power-Save, 3 Always-on, 1 Master Outlet.
