How to Choose the Right Extension Cord for Indoor/Outdoor Use

Whether indoors or outdoors, extension cords ensure your devices and equipment stay powered when their built-in cords can't reach an outlet. Selecting the right extension cord begins with understanding how they function and their intended applications.

The key distinction between indoor and outdoor extension cords lies in their construction, which is tailored to their specific environments. Indoor cords are typically lighter, shorter, and have a lower power capacity compared to outdoor models. In contrast, outdoor extension cords feature thick, rugged insulation for added durability. They are available in longer lengths and can handle higher electrical loads.

Outdoor extension cords are categorized into three main types:

Light-duty cords: Ideal for occasional use with small tools or short-term projects.

Medium-duty cords: Designed for frequent use with larger tools and heavier equipment.

Heavy-duty cords: Built for continuous operation in harsh conditions, capable of powering high-amperage tools on job sites.

Important Tip: While outdoor extension cords can safely be used indoors, indoor cords should never be used outside—they lack the necessary durability and weather resistance.
