The DuroMax XPX12050C 50-Foot 12-Gauge Triple Tap Extension Cord Is Built for Extreme Conditions
The DuroMax XPX12050C is a 50-foot, 12-gauge heavy-duty extension cord from DuroMax's premium blue SJEOOW line. It carries 120V power at up to 15 amps (1,875 watts) through 100% copper wire, with three outlets at a lighted end.
DuroMax designed this line for durability, with an oil- and chemical-resistant outer jacket and inner wire coating that stays flexible down to -58°F and usable up to 221°F. It is a strong choice for job sites, shops, generators and harsh weather.

DuroMax XPX12050C Features
12-Gauge 100% Copper Wire
12-gauge copper conductors handle most 15-amp tools and appliances with a lighter, more flexible cord than 10-gauge. For a 50-foot run, it is a practical balance of weight, flexibility and power delivery.
Triple Tap Lighted End
Three grounded outlets at the end let you run up to three tools, lights or appliances from one cord. The combined load must stay within the 15-amp, 1,875-watt rating.
The lighted end glows when the cord is energized, so you can confirm power at a glance.
Oil, Chemical and Weather Resistant
The SJEOOW jacket and inner insulation resist oil, chemicals and water, and the cord stays flexible from -58°F up to 221°F. That makes it easier to coil in winter and better able to handle hot surfaces, shop floors and job sites.
Grounded and UL Certified
A grounded three-prong plug and UL certification provide peace of mind on every job.
50 Feet of Reach
At 50 feet, it reaches across a yard, driveway or job site while staying manageable to coil. The cord weighs 7 lbs.
Real-World Applications
Generators. Run power from a portable generator's 120V outlet to appliances, lights or tools, with enough length to keep the generator well away from your home.
Job sites. Power saws, drills, chargers and work lights where outlets are scarce.
Yard and garage. Run trimmers, blowers, pressure washers, pumps and holiday lights.
Shops and harsh environments. Oil and chemical resistance suits garages, farms and industrial settings.
How It Compares to Common Alternatives
Versus light-duty household cords. 14- and 16-gauge indoor cords are not built for outdoor use or high-draw tools. This heavy-duty 12-gauge cord handles both.
Versus the DuroMax yellow XPC cords. The yellow SJTW cords cost less and are rated from -40°F to 140°F. The blue SJEOOW cords add oil and chemical resistance and a wider -58°F to 221°F range.
Versus a 10-gauge cord. 10-gauge has less voltage drop over long runs, which matters most at 100 feet. 12-gauge is lighter and easier to handle.
Is the XPX12050C the Right Fit
-
15-amp limit. Keep the total load at or below 15 amps (1,875 watts) at 120V, across all three outlets combined.
-
Not for 240V or 30A loads. To connect a generator to a home inlet box, use a 30A or 50A generator cord instead.
-
Uncoil fully. Unroll the cord completely before running heavy loads to prevent heat buildup.
-
Keep connections dry. Keep plug and outlet connections off the ground and out of standing water.
This may be a good fit if
- You need a 50-foot heavy-duty cord for tools, appliances or a generator
- You want three outlets at the end of one cord
- You want a cord that resists oil and stays flexible in extreme cold
Common Questions
Why Is a 12-Gauge Cord Rated at 15 Amps?
The rating is set by the standard 15-amp, three-prong plug and outlets. The 12-gauge wire helps reduce voltage drop over the cord's length.
Can I Use It With a Portable Generator?
Yes. Plug it into a 120V household outlet on your generator, and keep the generator outdoors, away from doors, windows and vents.
Is It Rated for Outdoor Use?
Yes. DuroMax lists it as outdoor rated, with an SJEOOW jacket.
What Warranty Does It Have?
DuroMax covers the XPX12050C with a 1-year parts and technical service warranty.
