How to Choose the Right Extension Cord or Power Strip (And Stay Safe)

Extension cords and power strips are everywhere — but using the wrong type can overload your system or even cause a fire. Here's how to choose the right one for your needs, and when to call in an electrician instead.

🔍 The Basics: Extension Cord vs. Power Strip

Extension Cord: Designed to temporarily bring power to places far from an outlet.

Power Strip: Lets you plug in multiple devices at once, often with surge protection.

Neither is a permanent solution — and both can become dangerous if misused.

✅ What to Look for in an Extension Cord:

Indoor vs. Outdoor Rated

Outdoor cords are thicker, weather-resistant, and marked with a “W”.

Gauge (Wire Thickness)

Lower numbers = thicker wires = more power.

Example: 14-gauge is good for lamps and laptops; 12-gauge for power tools or heaters.

Length

The longer the cord, the more voltage drops — use only as long as you need.

Amperage Rating

Match or exceed the wattage of the device you're plugging in.

⚡ What to Look for in a Power Strip:

UL Listed

Make sure it’s certified by a trusted safety lab.

Surge Protection

Especially important for TVs, computers, routers, and smart home gear.

Auto Shut-Off

Some strips cut power when they detect overloads.

USB Ports

Helpful for charging multiple devices without bricks.

🚫 What NOT to Do:

Don’t plug one extension cord into another

Don’t plug power strips into extension cords

Don’t run cords under rugs or furniture

Don’t use damaged or frayed cords

Don’t overload them with space heaters or appliances

🛠️ Pro Tip: If You Always Need an Extension Cord, You Probably Need More Outlets

Have a licensed electrician:

Add more wall outlets

Install ceiling or wall-mounted fixtures

Add GFCI-protected outdoor outlets

💬 Final Thought:

Extension cords and power strips should be tools of convenience, not crutches. Choose them wisely — and never use them as a substitute for proper wiring.
