5 Things to Know About Using a 100-Foot Extension Cord With a Leaf Blower

Use a 12-gauge cord for 100 feet A 14-gauge cord drops 5-6 volts under load, cutting air velocity by 10-20% and making the motor run hotter. A 12-gauge cord drops only about 3 volts, so performance loss is barely noticeable.

Thinner cords cause overheating Anything smaller than 12-gauge will make your leaf blower feel weak and may overheat the motor. This is especially risky with tools drawing 10 amps or more.

Expect some performance loss even with 12-gauge A 100-foot 12-gauge cord still causes a slight performance hit compared to a 50-foot cord. It works fine for most yards, but not the biggest ones.

Keep your 14-gauge cord for lighter tasks If you already own a 14-gauge 100-footer, use it for lights or a hedge trimmer. It’s not suitable for high-draw tools like leaf blowers.

Spend the extra $10 for 12-gauge The price difference between 14-gauge and 12-gauge is small. For reliable power delivery and motor safety, 12-gauge is the minimum for 100 feet.
