Surge Protectors review: cheapest insurance

The least glamorous purchase in this guide is also among the most defensible: a real surge protector costs a rounding error next to the television, computer, and console plugged into it. The catch is the word 'real' — the store shelf mixes genuine surge protectors with plain power strips that multiply outlets and protect nothing, and the packaging is engineered to blur the two. The tell is a stated protection rating and a recognized certification mark; no rating, no protection, no purchase.

Two habits make the purchase actually work. First, treat surge protection as consumable: the components that absorb surges degrade with each event, and a unit that has eaten a serious spike may keep passing power while protecting nothing. Units with a protection-status indicator light are worth choosing for exactly this reason, and anything that predates several storms deserves retirement. Second, place them where the value is — the home-office cluster, the TV stack — rather than buying one and declaring the house solved.

What you can skip: the escalating 'conditioner' tier sold to home users on promises of cleaner power and better performance. For ordinary electronics on ordinary household wiring, certified surge protection is the job, and it's done at commodity prices. Spend up for more outlets, better spacing for wall warts, or a longer cord — those are real. Spend up for purity adjectives and you've wandered into the cable aisle's cousin. For gear that must survive outages as well as spikes — desktops mid-save, network equipment — the step up worth considering is a battery backup unit, a different product with a real job.
