Buying Guide: How to Choose a 100Ft Outdoor Extension Cord
When I need to power something far from my house, a 100-foot extension cord is my go-to tool. But not all long cords are created equal, especially when they’re destined for outdoor use. Picking the wrong one can be inefficient at best and a serious safety hazard at worst. After going through my fair share of cords, I’ve learned what truly matters. Here’s what I look for to make sure I get a cord that’s powerful, durable, and safe.
First up, let’s talk about wire gauge. This is probably the most confusing but most important part. The gauge is a number that refers to the thickness of the wire inside the cord. A lower number means a thicker wire. Thicker wires can carry more electricity over longer distances without losing power (a phenomenon called voltage drop). For a 100-foot cord, you generally don’t want to go thinner than a 14-gauge wire for light-duty tasks like a string of patio lights. For power tools, lawn equipment, or a portable heater, a 12-gauge cord is a much safer and more effective bet. If you’re running something really demanding like a large air compressor or a welder, a 10-gauge cord is your best friend.
Next, you absolutely must check the rating. An outdoor extension cord needs to be rated for the job. Look for the letters W on the jacket. This stands for “Weather-Resistant” and means the cord is designed to handle moisture, sunlight, and temperature changes. Also, check the amperage and wattage ratings. A common rating is 13A/125V/1625W. Make sure the total wattage of the devices you plan to plug in does not exceed the cord’s rating. Overloading a cord is a primary cause of failure and fire risk.
The physical construction is another big deal. The jacket should be thick and robust. A rubberized jacket is often more flexible in cold weather and more resistant to abrasion, oil, and chemicals than a cheaper vinyl one. Look for a cord that is rated for heavy-duty or commercial use if you plan on dragging it across rough surfaces like concrete or gravel. The plug ends should be solid and, ideally, have a cover that flaps over the outlets to keep water and dirt out when not in use.
Finally, think about the little things that make a big difference in daily use. A built-in GFCI (Ground Fault Circuit Interrupter) plug is a fantastic safety feature, especially for use in damp conditions, as it can prevent severe electrical shocks. A lighted end plug lets you know at a glance that the cord is receiving power. And for storage, I find that cords with a built-in reel or a hanging hook are much easier to manage than a tangled mess in a bucket. Taking the time to consider these factors will ensure you get one of the best 100ft extension cords for outdoor use that will be a reliable part of your toolset for years.
Frequently Asked Questions
Can I use an indoor extension cord outside?
I strongly advise against it. Indoor extension cords are not built to handle outdoor conditions. Their jackets are thinner and lack the weather-resistant (W) rating needed to protect against moisture, UV rays from the sun, and temperature extremes. Using an indoor cord outside creates a significant risk of shock, short-circuiting, and fire. Always use a cord specifically marked for outdoor use.
What’s the difference between a 16-gauge and a 12-gauge 100-foot cord?
The main difference is power capacity and safety over distance. A 16-gauge cord is much thinner and is really only suitable for very light loads, like a single LED light strand, over a 100-foot run. If you try to run a power tool or a leaf blower through it, the cord will struggle, lose power (voltage drop), and can overheat dangerously. A 12-gauge cord is thicker, can handle more power (amps), and will deliver full voltage to your tool at the end of 100 feet, making it a much safer and more effective choice for most outdoor jobs.
Is it safe to plug two extension cords together to get more length?
This is a practice I try to avoid. Connecting multiple cords increases the total resistance in the circuit, which leads to greater voltage drop and heat buildup. This can damage your tools and create a fire hazard. If you absolutely must connect two cords, make sure they are both heavy-duty, outdoor-rated cords of the same gauge, and keep the total length as short as possible. It is always better to use a single, long cord rated for the total distance you need.
How should I store my outdoor extension cord?
Proper storage is key to making your cord last. I always make sure the cord is clean and completely dry before coiling it up. Avoid wrapping it too tightly, as this can stress and damage the internal wires over time. The best methods are a loose, over-under coil or using a reel designed for extension cords. Store it in a cool, dry place out of direct sunlight. Proper storage prevents kinks, tangles, and jacket degradation, ensuring your best 100ft extension cords for outdoor use remain in good working condition for many seasons.
What does a GFCI on an extension cord do?
A GFCI (Ground Fault Circuit Interrupter) is a crucial safety device, especially for outdoor electrical work. It constantly monitors the flow of electricity. If it detects even a tiny imbalance, like electricity leaking through water or through a person, it cuts the power in a fraction of a second to prevent a severe shock. Having a GFCI built directly into the plug end of your extension cord adds an extra layer of protection beyond what might be in your outdoor outlet.
