Power Strip vs Extension Cord: Choosing the Right Power Solution for Your Needs

Power Strip vs Extension Cord: Choosing the Right Power Solution for Your Needs

Have you ever found yourself staring at a tangled mess of cords and wondering which gadget you actually need to power your devices? Understanding the differences between a power strip and an extension cord can save you both time and hassle.

This article explores the unique functions of each, explaining what a power strip and an extension cord are, and how they serve different purposes. By comparing their features, you'll gain insight into which one suits your needs best. Uncover the essentials of the power strip vs extension cord and discover the right solution for your electrical setup.

What Is a Power Strip?

A power strip is a versatile electrical device that hosts multiple electrical outlets attached to one power cord allowing various devices to connect to a single power source simultaneously. Often equipped with surge protection this device ensures safety by preventing voltage spikes that could damage connected equipment. 

Power strips often feature a circuit breaker to enhance safety by cutting off the power if the load exceeds safe levels. This design expands the number of devices you can plug in and improves protection against electrical overloads.

What Is an Extension Cord?

An extension cord fundamentally extends the reach of an electrical outlet. Typically consisting of a long cable with one plug on one end and one or more sockets on the other end it provides a simple solution for powering devices that are too far from wall outlets. 

While not designed for permanent use or to handle heavy loads extension cords are indispensable for temporary setups or when flexibility in placement is necessary. 

How Does a Power Strip Differ from an Extension Cord?

Understanding the distinction between a power strip and an extension cord can maximize electrical safety and efficiency. 

1. Functionality: 

Power Strip: A power strip is a block that contains multiple electrical outlets. It allows multiple devices to be plugged into a single power source.

Extension Cord: An extension cord is a length of flexible electrical power cable. It is primarily used to extend the reach of an electrical outlet to more distant appliances or devices. 

2. Design and Usage: 

Power Strip: Typically, power strips are used in fixed locations such as offices or entertainment centers where multiple devices need power simultaneously.

Extension Cord: Designed for temporary use, extension cords are ideal for short-term projects or occasions when an appliance is used away from a fixed outlet. They are not intended for permanent or semi-permanent setups and should be unplugged and stored after each use. 

3. Safety Features: 

Power Strip: Offers advanced safety features including surge protection, grounding, and built-in circuit breakers. These features help protect connected devices from electrical malfunctions.

Extension Cord: Generally lacks the protective features of power strips. While some heavy-duty extension cords include a fuse for overload protection, they do not provide surge protection. 

4. Capacity: 

Power Strip: These can often support higher electrical loads than extension cords, making them suitable for powering multiple devices at once, including computers, televisions, and other electronics.

Extension Cord: While available in various lengths and gauges, they are best used for low-power devices unless specifically rated for higher loads. 

5. Regulatory and Compliance Considerations: 

Power Strip: Most power strips must meet specific regulatory standards, including certifications from organizations like Underwriters Laboratories (UL) or the Electrical Testing Labs (ETL). These certifications ensure that the power strip can handle the electrical load and has passed safety tests.

Extension Cord: Also subject to safety certifications, but the focus is often on the cord's durability and the safety of its electrical connections rather than on load-bearing capacity or surge protection.

Power Strip vs Extension Cord: Which One to Choose?

When it comes to choosing between a power strip and an extension cord, the decision largely depends on your specific needs for power distribution and safety features. Extension cords are ideal for simple tasks like extending the reach of a single power outlet, but they don't offer additional features or multiple outlets. Power strips, on the other hand, provide multiple outlets, often come with integrated safety features, and can serve various devices simultaneously. 

For those who need more than just extension, consider the benefits of modern power strips offered by Anker, which are equipped with advanced technology to enhance both convenience and safety.

1. Anker 524 Power Strip 

The Anker 524 Power Strip is a prime example of efficiency in a compact design, featuring 3 AC outlets, 2 USB-A ports, and 1 USB-C port, allowing you to power up to six devices at once. Its 30W USB-C port offers high-speed charging capable of powering tablets, phones, and some laptops quickly. Designed with a fire-retardant casing and internal safety shutters, it ensures superior protection, making it an ideal choice for both travel and home use due to its compact and portable design. 

2. Anker 521 Power Strip

Similarly, the Anker 521 Power Strip offers a clutter-free solution with its well-organized port placement—USB ports on the front and AC outlets at the back. This layout not only helps in managing space better but also simplifies accessibility. It powers up to six devices and uses Anker's exclusive ActiveShield safety system to monitor conditions continuously, ensuring safer operation.

3. Anker 615 USB Power Strip (GaNPrime 65W)

For those requiring more robust power output, the Anker 615 USB Power Strip incorporates cutting-edge GaN technology with two USB-C ports at 65W, providing rapid charging that can charge a MacBook Pro 14" to 50% in just 37 minutes. Its compact form factor and light weight make it perfect for both office settings and travel.

4. Anker 351 Power Strip

Lastly, the Anker 351 Power Strip is designed for heavy-duty use, featuring 12 AC outlets and multiple USB ports, including a 20W USB-C port that can fast charge an iPhone 13 up to 53% in 30 minutes. The optimized layout accommodates large plugs without overlap, and its comprehensive 8-point safety system ensures your devices are protected from electrical anomalies. 

Each of these Anker power strips offers unique features that cater to different needs, from high-speed charging and compact design to enhanced safety systems. When comparing these to a simple extension cord, the added functionality and safety features of power strips like these from Anker make them a superior choice for anyone looking to manage multiple devices safely and efficiently. Whether you're at home, in a dorm room, or traveling, Anker provides reliable solutions that ensure your devices stay powered and protected.


In the power strip vs extension cord debate, understanding their distinct roles and safety features is key to making an informed decision. Power strips are designed for durability and multiple device connections, offering superior protection against electrical surges and overloads. 

Extension cords, while flexible and convenient for temporary use, lack the advanced safety mechanisms of power strips and are more susceptible to wear and tear. By recognizing the unique advantages and limitations of each, you can ensure the safe and efficient use of your electrical devices, avoid potential hazards, and optimize performance. Always follow manufacturer guidelines for safe operation.


Can I Use an Extension Cord and a Power Strip Interchangeably?

No, extension cords and power strips should not be used interchangeably. Extension cords are designed for temporary use to extend the reach of an outlet, while power strips provide multiple outlets and often include surge protection. Using them interchangeably can lead to safety hazards, such as overloading and potential fire risks.

Can I Use an Extension Cord with a Power Strip?

It is generally not recommended to use an extension cord with a power strip. Doing so can lead to increased risk of overloading the circuit, which might cause a fire hazard or damage to the electrical devices connected. Moreover, this setup can violate electrical codes and safety standards.

Is It Safe to Plug a Major Appliance into a Power Strip or Extension Cord?

No, it is not safe to plug a major appliance into a power strip or extension cord. Major appliances require a lot of power and should be plugged directly into a wall outlet to avoid risks of overheating, electrical fires, and circuit overloads.
