Is a Power Strip Safer Than an Extension Cord?
When managing multiple devices, you might wonder whether a power strip or an extension cord is the safer choice. While both serve similar purposes, their design and use differ significantly.
Power strips generally offer additional safety features like surge protection, making them safer than extension cords for specific applications.
Let’s explore the differences, risks, and best practices for using power strips and extension cords safely.
Are power strips better than extension cords?
Power strips and extension cords both provide additional outlets, but are power strips the better choice?
Power strips are often better than extension cords for indoor use because they offer built-in surge protection and more outlet options.
However, the best choice depends on the specific use case and safety considerations.

Advantages of power strips
- Surge protection: Many power strips come with surge protection, safeguarding devices from voltage spikes.
- Multiple outlets: They allow you to plug in several devices simultaneously.
- Compact design: Power strips are typically neater and more organized than extension cords.
When to use power strips
Power strips are ideal for:
- Electronics: Computers, televisions, and other devices that benefit from surge protection.
- Indoor use: They’re designed for dry environments.
Advantages of extension cords
- Portability: Extension cords are lightweight and easy to move around.
- Versatility: They work well for both indoor and outdoor purposes, depending on their rating.
- Length options: Extension cords offer greater flexibility in distance coverage.
| Feature | Power Strips | Extension Cords |
|---|---|---|
| Surge Protection | Yes (in most models) | No |
| Portability | Moderate | High |
| Outdoor Use | Rare | Common (if rated) |
Choosing between a power strip and an extension cord comes down to the specific requirements of your setup.
Why are extension cords or power strips not safe?
Both extension cords and power strips can become hazardous if not used properly. What risks should you be aware of?
The primary risks include overloading, misuse, and damage, which can lead to fires, electrical shocks, or device failures.
Understanding these risks helps you use both tools more safely.
Dive deeper: Common dangers of extension cords and power strips
1. Overloading
- Plugging in too many high-wattage devices can cause overheating.
- Power strips without surge protection are particularly vulnerable to damage from electrical surges.
2. Misuse
- Using indoor-rated cords or strips outdoors exposes them to moisture, increasing the risk of electrocution.
- Running cords under rugs or furniture can trap heat and damage insulation.
3. Physical damage
- Frayed wires, cracked plugs, or exposed connections pose fire and shock hazards.
- Dropping or stepping on a power strip can damage internal components.
4. Lack of maintenance
- Not inspecting cords or strips for damage can lead to undetected risks.
| Risk | Cause |
|---|---|
| Overloading | Plugging in too many devices |
| Misuse | Using tools in inappropriate settings |
| Physical damage | Wear and tear over time |
By staying mindful of these risks, you can use power strips and extension cords more responsibly.
What are the disadvantages of power strips?
While power strips are often seen as safer, they’re not without their drawbacks. What are the key disadvantages?
The disadvantages of power strips include limited load capacity, vulnerability to misuse, and potential for overloading.
These limitations make it crucial to understand the appropriate use of power strips.
Dive deeper: Downsides of power strips
1. Limited power handling
- Most power strips can only handle a certain amount of wattage. Exceeding this limit causes overheating.
- Using multiple power-hungry devices on one strip increases fire risks.
2. No outdoor use
- Power strips are not designed for outdoor environments. Exposure to water or dirt can damage internal components.
3. Over-reliance on multiple devices
- Plugging too many devices into a single strip can overload the circuit.
4. Lack of surge protection in basic models
- Budget power strips may not include surge protection, leaving devices vulnerable to voltage spikes.
| Disadvantage | Why It Matters |
|---|---|
| Limited power handling | Risk of overheating |
| Not outdoor-friendly | Unsuitable for wet environments |
| Over-reliance | Potential circuit overload |
Being aware of these drawbacks ensures that you don’t misuse power strips in ways that compromise safety.
What is the safest type of extension cord?
Not all extension cords are created equal. What features should you look for in the safest extension cords?
The safest extension cords are heavy-duty cords with grounded plugs and appropriate ratings for their intended use.
A high-quality cord minimizes risks and ensures reliable performance.
Dive deeper: Choosing a safe extension cord
1. Match the gauge to the job
- Thicker wires (lower gauge numbers) can handle more current safely.
- For power tools or heavy appliances, choose a 12-gauge or lower cord.
2. Look for outdoor ratings
- Outdoor-rated cords are designed to withstand moisture and UV exposure. Look for labels like “SJTW” indicating suitability for outdoor use.
3. Grounded plugs
- A grounded (three-prong) plug provides an extra layer of safety by reducing the risk of electrical shocks.
4. UL or ETL certification
- These certifications ensure that the cord meets safety standards.
| Feature | Purpose |
|---|---|
| Thick gauge | Handles higher currents |
| Outdoor rating | Resists environmental elements |
| Grounded plugs | Reduces shock risk |
| Safety certification | Meets industry standards |
By choosing a cord with these features, you ensure safety for both indoor and outdoor applications.
Conclusion
While power strips offer advantages like surge protection and multiple outlets, extension cords excel in portability and versatility. Both tools come with risks if used incorrectly, but by following safety guidelines and selecting the right product for your needs, you can ensure reliable and secure use.
