Extension Cords
Buying GuideFrom cord length to amperage rating, here are a few factors to consider before purchasing an extension cord.
Number of Outlets
Most extension cords come with just one outlet that supports a single device. If you want to plug in more than one device, select an extension cord with multiple outlets
Amperage Rating
Every power cord should have an amperage rating that signals how much power it can handle, with a higher amperage rating denoting a more powerful cord. Most extension cords are rated to support around 13 amps, though some models like the Southwire Outdoor Extension Cord can handle up to 15 amps.
Cord Length
Power cords can be as short as six feet and as long as 100 feet. If you need an extension cord to power indoor electronics, a cord under 20 feet should suffice. If you need to power corded tools like electric chainsaws, a cord that’s 50 feet or longer may be a better choice.
Number of Prongs
The majority of extension cords are equipped with three-prong outlets, though some indoor models have two-prong outlets. If you need to power a few device chargers, a two-prong extension cord should work. If you need to power small appliances or tools like electric drills, use a three-prong model, as this type of cord tends to have an extra prong.
FAQ
What does the gauge of an extension cord refer to?
The gauge of an extension cord refers to the diameter of the metal conductors it holds. Smaller wire gauges denote thick extension cords that can carry large amounts of electricity. For example, 12-gauge cords can handle tool loads between 10 and 15 amps. Many outdoor extension cords have small gauge numbers to support heavy-duty machinery.
