Surge protectors don't last forever. Like lightbulbs, they need to be replaced every few years when they wear out. Just because your old surge protector passes power to your devices doesn't mean it's still actively protecting them—in fact, you probably need a new one. After assessing more than 30 hours of research, and 32 hours of testing by an electrical engineer, we found that most surge protectors that cost just above $20 will provide adequate protection from surges. Our extensive research and testing showed that more-expensive units didn't provide enough additional benefit to be worth their higher cost. And of the units we tested, our top pick is the 10-outlet Tripp Lite TLP1008TEL, because it stops passing power when it's no longer effective at blocking surges.
Most surge protectors rely on an easily ignored LED indicator to tell you when they've ceased protecting your gear. We picked the TLP1008TEL because when its ability to block surges wears out, it cuts the power off entirely. So long as your devices are energized, you know that surge protection remains in place and have no ambiguity as to when it needs to be replaced.
