Electronics are getting more and more expensive, and it’s not uncommon for homes to have thousands of dollars tied up in a high-end entertainment center. How would you feel about having that all busted by a random lightning strike or spike in the electrical grid? Probably not something that you want to think about, but the truth is that it does happen. Your best protection against something like that is to have a surge protector.
Surge protectors might look just like a regular power strip, but they are made to withstand electrical surges. Some of them even come with a guarantee for the connected equipment, but it might be worth looking into how easy it is to get a payout from one of those guarantees before you see it as a good selling point.
A surge protector is only good for a few spikes, so if you see an indicator light telling you that it has been spent, it is time to get a replacement. For some, the electrical grid might be unstable enough that this is an issue, while others can use the same surge protector for many years.
