100ft 12/3 12 AWG Portable Power Cable - Heavy Duty SJOOW 300V

In this review the 100ft 12/3 12 AWG Portable Power Cable is evaluated for contractors, event technicians, and marine users who need a rugged, all-weather cord. The bottom line: this SJOOW 300V cable is best for temporary power runs and heavy-duty portable equipment because its stranded oxygen free copper conductors and thick PVC jacket deliver reliable conductivity and resistance to oil, water, and chemicals. The reviewer found it a practical, value-oriented choice when durability and conductivity matter more than an extra grounding conductor.

Key Features

• Rugged SJOOW jacket: The robust PVC jacket resists oils, acids, water, and chemicals so the cable holds up in harsh outdoor and industrial conditions.
• Oxygen Free Copper conductors: Stranded OFC with 72 strands per conductor provides improved conductivity and corrosion resistance for steady current delivery.
• Temperature range: Rated to perform from -40C to 90C, making it suitable for cold job sites and hot equipment bays without premature degradation.
• Three conductor design: The 12/3 configuration supplies hot, neutral and ground paths for many portable power and lighting applications.
• 100 ft length: A full 100 ft run reduces the need for splices or additional extenders when powering remote tools and temporary lighting.

Who It's For

This cable is aimed at tradespeople, event crews, and operators who need a long, heavy duty cord for portable tools, generators, pumps, lighting rigs, and marine deck equipment. Its combination of stranded OFC conductors and SJOOW jacket makes it well suited to construction sites, outdoor events, and industrial temporary power distribution.

Those who need a cable with an extra separate grounding conductor or a 3+1 configuration should look elsewhere; the product is specifically a 3-conductor 12AWG cord with no additional ground wire. Buyers who require jacketless hookup wire for permanent internal wiring should also choose a cable designed for that use.

Pros & Cons

Pros

• Durable SJOOW PVC jacket stands up to oils, water, and chemicals encountered on job sites.
• Stranded OFC conductors deliver good conductivity and improved corrosion resistance for dependable current delivery.
• 100 ft length minimizes the need for extensions during temporary power runs.
• Suitable temperature range for winter and summer field use.

Cons

• Not a 3+1 style; there is no extra separate grounding wire, so confirm compatibility with your equipment.
• Some users report the conductor thickness feels thin compared with solid core wire, though flexibility is expected with stranded construction.

Our Verdict

The 100ft 12/3 12 AWG SJOOW cable is a practical choice for anyone needing a long, flexible, and durable portable power cord for outdoor, industrial, or marine temporary power. It offers solid conductivity and environmental resistance at an attractive value, but confirm you do not require a separate extra grounding conductor before ordering.

Frequently Asked Questions

Is this cable rated for outdoor and marine use?
Yes, the SJOOW PVC jacket and temperature rating make it suitable for outdoor and many marine deck applications where a flexible, water-resistant cord is needed.

Does it include an extra grounding wire?
No, this is a 3-conductor 12AWG cable and does not include an additional separate ground conductor or 3+1 configuration.

What advantage does OFC give?
Oxygen Free Copper stranded conductors improve conductivity and corrosion resistance compared with standard copper, enhancing current capacity and longevity in harsh conditions.
