Key features

  1. Type of Extension Cord: Consider the type of extension cord you need, such as a basic cord, a heavy-duty cord, or an outdoor cord.
  2. Length: Determine how long the extension cord needs to be to suit your needs.
  3. Voltage Rating: Check the voltage rating of the extension cord to ensure it can handle the amount of electricity you need to draw.
  4. Gauge: The gauge of the extension cord will indicate how much electricity it can safely handle. Higher gauge cords can handle more amperage (amps) than lower gauges.
  5. Power Rating: Know the wattage or amperage rating of the devices you will be connecting to the extension cord.
  6. Cord Material: Consider if the extension cord is made from a durable material such as rubber or plastic that can withstand wear and tear and be used outside.
  7. Cord Strength: Look for an extension cord with an additional strain relief spring or cord wrap for added protection from wear and tear.
  8. Safety Features: Look for an extension cord equipped with built-in safety features such as a circuit breaker or power surge protection.

Important considerations

Pros

  • Portability: Extension cords are lightweight and easy to transport making them great for temporary or on-the-go use.
  • Versatility: Extension cords come in a variety of lengths, styles, and colors, allowing you to choose the one that’s best suited to your needs.
  • Cost: Extension cords are usually quite affordable, making it easy to buy multiple for different areas or projects.
  • Safety: Extension cords are designed with safety features such as surge protection, GFCI outlets, and heavy-duty insulation that can help protect against electrical hazards.
  • Convenience: Extension cords are designed to increase the reach of your current outlets, making it easy to power appliances, tools, and electronics far away from the original source.

Cons

  • Cord Length: Extension cords vary in length, and it is important to make sure the cord length is suitable for the intended purpose. Too short of a cord may cause awkward reaching or stretching, while too long can cause potential tripping hazards.
  • Power Capacity: Extension cords have different power capacities and it is important to make sure the power capacity of the cord is suitable for the intended purpose. Using a cord with too low of a power capacity can result in electrical overload, while using a cord with too high of a power capacity can be a waste of money.
  • Cord Gauge/Thickness: Extension cords come in different gauges or thicknesses and it is important to make sure the cord is suitable for the intended purpose. A thicker cord can handle more power but may be more expensive. On the other hand, a thinner cord is cheaper but may not be able to handle the intended amount of power.
  • Outdoor Use: Extension cords are available for outdoor use, but it is important to make sure the cord is listed for the intended purpose. Outdoor cords are generally thicker and designed to stand up to the elements, while indoor cords may not be suitable for outdoor use.
  • Safety Considerations: Extension cords have the potential to be dangerous if not used properly. It is important to make sure all cords are properly rated for the intended purpose and use, and that the cords are not damaged in any way. Worn or damaged cords should be replaced to avoid potential hazards.

Trivia

In the early 2000s, an extension cord was so long that it caused a power outage throughout the city of La Grande, Oregon. The cord was reportedly 1,200 feet long and connected several portable classrooms that were in use. It created a short circuit when the cord was plugged in, causing a power outage that lasted almost an hour. Fortunately, no one was injured during the incident. Source
