Best Surge Protector

A surge protector is cheap insurance for expensive electronics. One power spike can destroy a TV, computer, or gaming console instantly. The right protector absorbs that spike and saves your gear. I compared joule ratings, outlet counts, cord length, and warranty coverage to find the best options.
How I researched
I compared joule ratings and clamping voltages, tested outlet spacing for bulky adapters, read r/hometheater and r/buildapc threads on surge protection, and verified Amazon warranty claim experiences from review data.
