The Belkin 12-Outlet Surge Protector protects your electronic devices from surges and spikes. This 4320-Joule surge protector features 12 surge-protected outlets to provide powerful protection for your workstations, printers, broadband modems, home theater systems and everyday household electronics. It features a cord-management system that helps keep cables organized, and a rotating outlet design to allow extra room for large AC adapter blocks. SURGE PROTECTION SAFETY If a surge protector ever becomes hot to the touch, shut off the unit immediately. Never daisy-chain power strips to other power strips or extension cords. Never allow a power strip to be exposed to a moist environment. Avoid running too many high-energy consuming appliances through a single surge protector at once. High-energy consuming electronics/appliances include window AC units, space heaters, refrigerators, washers/dryers etc. Only one power strip should be plugged into a single two-outlet electrical socket. Never cover a surge protector with carpet, furniture, or anything that would limit or prevent air circulation. IMPORTANT: The protective components inside surge protectors that absorb over-voltage spikes will eventually wear out. Most estimates put the average lifespan of a surge protector from 3 to 5 years
