Power surges — from lightning, grid switching, or large appliances cycling — can damage sensitive electronics over time. Surge protection diverts that excess voltage before it reaches your devices.
Power strip vs surge protector
A basic power strip just adds outlets — it offers no protection. A surge protector looks similar but contains components that absorb voltage spikes. Check the joule rating: higher means more protection, and surge protectors wear out over time and need replacing.
Protect the important stuff
Use quality surge protectors on computers, TVs, gaming consoles, and home-office gear. Look for an indicator light that shows the protection is still active — many people keep using a surge protector long after its protection has worn out.
Whole-home protection
A whole-home surge protector installed at the electrical panel by an electrician stops large surges at the entry point, protecting hardwired appliances and adding a layer before your plug-in protectors. The two work best together.
