Do surge protectors really work?

Yes—good surge protectors can reduce damage from common voltage spikes and switching surges. For best protection, use a layered approach: a whole-home surge protector plus point-of-use protectors for sensitive electronics.

What is UL 1449 and why does it matter?

UL 1449 is the safety standard used to evaluate surge protective devices. Choosing a protector listed to UL 1449 helps ensure it meets recognized performance and safety testing.

How many joules should a surge protector have?

Higher joule ratings generally mean the protector can absorb more surge energy over time. For TVs, computers, and home offices, many homeowners choose higher-joule models. Also look for UL 1449 listing and a protection indicator light.

When should I replace a surge protector?

Replace it if the protection indicator light is off, it has been in a major surge event, it’s physically damaged, or it’s old and heavily used. Surge components wear down over time.

Is a power strip the same as a surge protector?

No. A basic power strip just adds outlets. A surge protector includes surge-suppression components and should be labeled as a surge protective device (often with a joule rating and UL 1449 listing).

Can lightning still damage electronics even with surge protection?

Direct or very close lightning strikes can overwhelm many devices. Surge protection still helps for everyday surges and many storm-related events, but it is not a guarantee against direct lightning.

The 7 Best Surge Protectors for Home Safety (Electrician-Recommended)

Not all “surge protectors” actually protect your home the way you think. Some are just basic power strips. Others provide real surge suppression—but still aren’t the right fit for every location. This guide breaks down the best surge protector types for common areas (TVs, offices, garages, and smart homes), plus the features that matter most so you can shop confidently.

Quick electrician note:
The best protection is a layered setup: (1) whole-home surge protection + (2) quality point-of-use protection for sensitive electronics. You don’t have to do everything at once—start with the areas that have the most expensive gear.

First: power strip vs surge protector

Power strip

Adds outlets
May include a switch
Does not necessarily protect against surges

Surge protector (SPD)

Designed to reduce damage from voltage spikes
Often lists a joule rating and “UL 1449”
Best when it has an indicator light for protection status

What to look for (simple buying checklist)

My “don’t skip these” features

UL 1449 listed (recognized surge protector safety/performance standard)
Protection indicator light (lets you know if it’s still protecting)
Enough outlets + spacing for bulky plugs (especially for TV/entertainment)
Right cord length (avoid running cords under rugs or through doorways)
Strong build quality (solid housing, good strain relief, reputable brand)

Safety reminder: Never daisy-chain power strips (strip into strip). Never use a surge strip for high-draw heaters. If you need more permanent outlets, that’s a “call an electrician” situation.

Stop and call a licensed electrician if you have:

Burning smell, scorch marks, or melted plastic at an outlet
Warm/hot outlets, buzzing/crackling sounds
Breakers that trip repeatedly during normal use

The 7 best surge protector picks (by real-life location)

Instead of chasing a single “best,” I recommend matching the protector to the room and the equipment. Below are the most useful categories I install and recommend—each one solves a specific problem.

1) Whole-home surge protector (best overall protection layer)

Protects many circuits at the panel level (layer 1)
Helps reduce damage from common surges and switching events
Best installed by a licensed electrician

2) TV / entertainment center surge protector

More outlet spacing for bulky adapters
Great for TV, soundbar, streaming box, game console
Look for protection status indicator

3) Home office / computer surge protector

Ideal for PC/Mac, monitors, router, printer
Often includes spaced outlets + cord management
Bonus if it includes EMI/RFI filtering (nice-to-have)

4) Smart home / router surge protector (network focus)

Good for modem, router, mesh nodes, smart hubs
Choose a quality brand + indicator light
Keep it accessible (so you can replace if protection fails)

5) Garage / workshop surge strip (rugged build)

More durable housing for tougher environments
Great for battery chargers, bench tools (not heavy heaters)
Look for a cord that can handle normal wear

6) Wall-tap surge protector (space saver)

Useful where cords get messy (kitchen counter gadgets, bedrooms)
Choose one that sits firmly and doesn’t wobble
Great “small win” upgrade for older homes

7) Travel / compact surge protector (optional)

Helpful for hotels, temporary setups, and laptops
Look for a reputable brand + safety listing
Not a substitute for home whole-house protection

Electrician tip:
If you’re only going to buy one right now, start with the area that has your most expensive electronics: usually the TV area or the home office. Then plan a whole-home surge protector as the next step.

Where surge protectors get misused (and cause problems)

Space heaters: Plug them directly into a wall outlet. If you need an extension, it’s the wrong heater or the wrong room setup.
Daisy-chaining strips: Strip into strip is a common overheating hazard.
Running cords under rugs: Creates heat buildup and damage risk.
Loose outlets: A loose plug fit can create arcing and heat. That outlet should be replaced by a qualified electrician.

When to replace a surge protector

The protection indicator light is off (or missing)
It has taken a big hit (storm event) and you’re unsure
It’s physically damaged, cracked, or loose
It’s old and heavily used—surge components wear down over time

Bottom line:
Surge protection is cheap compared to replacing TVs, computers, routers, and smart home gear. Use the right surge protector for the room, avoid unsafe overloads, and consider whole-home surge protection for the best results.
