The one-outlet Home Series SurgeCube from Belkin offers wall-mount-direct, plug-in surge protection for your general electronics, home appliances, and more. This single outlet model boasts 885 joules, 45,000-Amp maximum spike current, and a lifetime $50,000 Connected Equipment Warranty for your peace of mind.Please note: The protective components inside surge protectors absorb over-voltage spikes to protect your connected devices which means they will eventually wear out. Replace them every 3 years or immediately after any over-voltage spike event such as a thunderstorm or power outage because surge protectors degrade faster if they are exposed to high intensity events. Periodically check the surge protector enclosure and cable for signs of wear or heat distress. Replace an expired surge protector with a new one at the end of its useful life.
