Prices come from Amazon and change often. The price on Amazon at checkout is the one that applies.
How to Choose Extension Cords
Length Matters
The length of the extension cord is important. A cord that is too short may not reach your outlet. A good rule is to measure the distance from your outlet to the device you want to power. Consider cords of at least 6 feet for indoor use and longer cords for outdoor applications. Typically, a 25-foot cord is a safe choice for outdoor use.
Outlets Count
Check how many outlets you need. Some cords have multiple outlets, while others have just one or two. For everyday use, choose a cord with at least 3 outlets. If you want to power multiple devices, like phones and laptops, look for cords with 6 or more outlets, or those that include USB ports.
Safety Ratings
Ensure your extension cord has safety certifications. Look for ETL or UL marks, which show the cord meets safety standards. These certifications are important for preventing overheating and reducing fire hazards. If you plan to use it outdoors, ensure it is rated for outdoor use to withstand weather conditions.
Surge Protection
Consider if you need surge protection. Some extension cords have built-in surge protectors. This feature safeguards your devices from voltage spikes. If you are connecting sensitive electronics, like computers or TVs, choose a cord with surge protection.
Flat Plugs for Space Saving
Flat plugs can save space and are more convenient for tight spots. If you want to place furniture against the wall, a flat plug allows this without blocking outlets. This is useful in bedrooms or offices where space is limited.

Frequently asked questions
What are extension cord reviews?
Extension cord reviews provide insights into various products available. They highlight features like length, safety ratings, and outlet availability.
How do I choose an extension cord?
To choose an extension cord, consider the length you need, how many outlets are required, and if you need safety features like surge protection.
Are flat plugs better?
Flat plugs can save space and help fit your furniture closer to the wall. They are often more convenient in tight spaces.
What does ETL listed mean?
ETL listed means that the product has been tested for safety and meets specific standards. This is important for ensuring the cord is safe for use.
Can I use indoor cords outside?
Not all indoor cords are safe for outdoor use. Always check the specifications to ensure the cord is rated for outdoor applications.
What to look for
Power Rating
The power rating indicates how much power the extension cord can handle safely. Most standard cords have power ratings of 15 amps, which is sufficient for many household devices. For high-power appliances, look for cords rated higher than 15 amps. A higher rating allows you to use more devices without overload.
Gauge of the Cord
The gauge of the cord affects its capacity to carry current safely. A lower AWG number means thicker wires, which can handle more power. For everyday use, a 16 AWG cord is fine. For heavy-duty use, choose a 14 AWG or lower. Always match the gauge to the intended application to prevent overheating.
Weather Resistance
If you plan to use the cord outdoors, check for weather resistance features. Cords marked as waterproof or weatherproof can withstand rain and moisture. Look for cords with protective sheaths that prevent wear and tear from the elements. This is critical for safety and longevity.
Type of Outlets
Consider the type and number of outlets on the extension cord. Look for cords that offer a combination of AC and USB outlets. Some cords have features that allow for simultaneous use without blocking other outlets. Choosing the right combination makes powering multiple devices easier.
Portability
For those who need to move cords around frequently, consider the weight and bulk of the extension cord. Lighter cords are easier to transport. Look for compact designs that are easy to store. Portability is especially important for outdoor activities or travel.
