Do I Really Need a Surge Protector for my TV or Computer?

Quick Answer: Yes — use a surge protector for every TV, PC, and game console. Look for ≥2,000 joules, UL 1449 safety listing, and auto-shutoff. Skip bare power strips with no surge rating.

Power spikes are cheap; fried electronics aren’t. A proper surge protector absorbs voltage spikes (lightning nearby, utility blips, A/C or fridge kick-on) before they reach your TV, desktop, NAS, or console. If the protector takes a big hit, most good ones sacrifice themselves and cut power — which is exactly what you want.

What to look for (30-second checklist)

  • Joules: The higher the number, the more total energy it can absorb. Aim for 2,000–4,000 J for home A/V and PC setups.
  • UL 1449 Listed: Ensures it’s actually surge-tested (not just a power strip).
  • Auto-shutoff / protection light: Cuts power when protection is spent. Replace after any major surge or if the protection light goes out.
  • Ports you need: USB-A/USB-C, spaced outlets for bricks, optional coax/Ethernet if those lines enter your gear.
Recommended Picks (Fast, Reliable, Good Value)
1) Everyday Power Strip (Good for TVs/PCs)
Target specs: 8–12 outlets, ≥2,000 J, UL 1449, protection light.

3) Line Protection for TV Internet/Cable
If your TV/streamer is fed by coax or Ethernet, consider protecting that line too.

When to replace a surge protector

  • After a major storm or power event.
  • If the “protected” light is off or the unit auto-shut off.
  • Every 3–5 years as cheap insurance (heavy surge areas may need sooner).

FAQ

Do I need a surge protector if I use a UPS?
Yes — most decent UPS units already include surge protection. If yours doesn’t list it, add a protector upstream.

Can I daisy-chain power strips?
No. Use one quality surge protector per outlet. Daisy-chaining is a fire and code risk.

Will a surge protector stop lightning?
Nothing guarantees lightning protection. A good protector helps with nearby strikes and utility spikes. For full protection, consider whole-home surge plus point-of-use devices.
