Surge-protected power strips are portable blocks of electrical sockets that provide power to several devices from a single outlet while protecting the connected devices from harm caused by voltage spikes. Surge protectors, also known as surge suppressors, absorb excess voltage and direct it to the ground line, preventing it from reaching connected electronics. The joule rating of a surge protector indicates how much energy it can absorb before failing. A higher number suggests that you are better protected. These outlet strips are often used to provide additional outlets in situations where the number of devices exceeds the number of wall receptacles available. They are lightweight and portable, allowing them to be unplugged and relocated as needed.They're ideal for use in homes, offices, medical facilities, and industrial settings where power spikes are a concern.
