The Rundown
- Our favorite outdoor extension cords are the Voltec Pro Outdoor Extension Cord (50 Feet, 12 Gauge, 15 A) and the US Wire & Cable 12/3 SJTW Outdoor Lighted Extension Cord, 50 Foot.
- A quality outdoor cord must safely transmit power and withstand daily wear from elements like rain, snow, and critters.
- Lower gauge cords, such as 12-gauge, offer higher amperage capacity, while longer cords may feature thinner wiring for easier management.
Whether you’re hanging outdoor lights or running power to an unreachable corner of your yard, a durable outdoor extension cord is a vital component of home life.
Be careful not to move your indoor cords outside, for using power tools or enjoying your deck. If not just to prevent electrical shocks, or worse. A quality outdoor cord should effectively transmit power and safely withstand daily wear and tear—rain, snow, tall grass, creeping critters, and just about any other annoyance.
After hours of exploring different options, we’ve determined that the Voltec Pro 12-gauge outdoor extension cord is the best extension cord money can buy. It combines an impressive power capacity, a useful length of 50 feet, a fortified wall outlet locking component, and overall value that makes it a clear front-runner. However, there are many other great extension cords of varying lengths and power capacities that are certainly worth looking into.
What Is Power Transmission for Outdoor Extension Cords?
In the simplest terms, the amount of power a cord can hold is related to the size of the wiring inside of the cord and the length of the cord. The longer the distance that power needs to travel, the thicker the internal conductive copper wiring needs to be. Cable thickness is measured in AWG, or American Wire Gauge, in which lower numbers signify thicker cables. For example, a 12-gauge cable has thicker conductive wiring than a 16-gauge cable.
Because of the increased thickness of the conductive wires, lower gauge cords are rated to carry a higher amperage. Typically, short extension cords offer lower gauges and higher power ratings, while longer extension cords have thinner high gauge wiring that makes the cord easier to manage.
Most of the top cords on our list are rated for 15 amps (15 A) and can hold and safely transmit power for just about any application. Some cords are rated for lower amperage but are still useful in lower-power applications.
It’s important to note that each cord is rated for a certain number of amps. Constantly over-powering a low-rated extension cord is not only less effective but can also be dangerous. Running too much power through a low-power rated extension cord, such as a 100-foot 16-gauge cord, can actually cause damage from voltage drop and even fire from the overload.
While we still considered some 16-gauge extension cords because of their useful length and affordability, these cords don’t have any safety features for heavy machinery or other high-power applications.
