How often this page is updated
This page is reviewed and updated regularly to ensure the information is accurate. We check for new products and trending features every few months.
What to look for
Cord Length
Cord length is very important when choosing an extension cord. Longer cords allow you to reach further away outlets. If you need to connect devices that are far apart, look for cords that are at least 25 feet long. Shorter cords are better for small areas.
Number of Outlets
Consider how many devices you need to power. Most extension cords range from 2 to 12 outlets. If you need to plug in multiple appliances at once, choose a model with at least six outlets. Less can be limiting.
Weather Resistance
If you plan to use your extension cord outdoors, ensure it is weather resistant. Look for cords labeled as waterproof or made of heavy-duty materials. These cords can withstand rain and snow without damage.
Surge Protection
Surge protection is essential for protecting your devices from power spikes. Some extension cords come with built-in surge protectors. These can help prevent damage to sensitive electronics, so always consider this feature.
Safety Ratings
Always check for safety ratings on extension cords. Look for cords that are ETL or UL listed, which means they meet safety standards. This ensures that the cords have been tested for safety and reliability.
How to Choose Extension Cords
Determine Your Power Needs
First, identify how many devices you plan to use. If you have multiple devices, look for an extension cord with at least six outlets. This prevents overcrowding and ensures each device can plug in safely.
Choose the Right Length
Measure the distance from your outlet to where you’ll be using the devices. If it’s more than 25 feet, consider a longer cord. This allows easier access without stretching the cord too thin.
Look for Additional Features
Consider if you need USB ports for charging. Many newer extension cords come with USB-A or USB-C ports. This feature adds convenience for charging devices without needing separate chargers.
Check the Gauge of the Cord
Cord gauge affects how much power it can handle. Look for cords with a lower gauge number (like 16 AWG) for heavier usage. Higher gauge numbers are fine for lighter loads, like small devices.
Verify Safety Certifications
Always check for safety certifications like ETL or UL. This ensures that the extension cord meets safety standards for electrical use. Avoid cords without these certifications as they can pose safety risks.
