18/4 SJOOW Wire 200FT 18 AWG 300V SJOOW Cable - Durable 4-Conductor

In this review the 18/4 SJOOW Wire 200ft is evaluated as a heavy-duty, portable power cable aimed at tradespeople and facilities that need robust, weather-resistant cordage. The bottom line: this 18 AWG 300V SJOOW cable is best for temporary power runs, generators, lighting rigs, and marine or industrial use where an oil- and water-resistant jacket and flexible stranded conductors matter most. It stands out because the conductors are oxygen-free copper, which improves conductivity and corrosion resistance compared with ordinary stranded wire.

Key Features

• Oil, water and acid-resistant jacket: The PVC outer jacket resists harsh chemicals and outdoor exposure so the cord holds up in demanding environments.
• Wide temperature range: Rated for use from -40C to 90C, the cable can be deployed across cold winters and hot jobsite conditions without rapid degradation.
• Oxygen-free copper conductors: Each of the four conductors is made from 41 finely stranded OFC strands, which enhances conductivity and heat dissipation for reliable current carrying.
• Flexible 18 AWG construction: The 18/4 stranded build balances flexibility and durability, making it suitable for portable tools, lights, and temporary power distribution.
• 200 ft bulk length: A single 200 ft length reduces the need for splices and extensions on larger jobs or temporary setups, simplifying deployment.

Who It's For

The cable is ideal for electricians, rental houses, event production teams, and contractors who require a flexible portable cord that tolerates oil, water, and outdoor exposure. It fits situations such as powering generators, motor leads, portable lighting, and temporary power distribution where a 4-conductor 18 AWG cable is suitable.

Those who need a dedicated equipment grounding conductor or a 4+1 style cable should look elsewhere, since this product contains four current-carrying conductors only and does not include a separate grounding conductor. Also, projects requiring thicker gauge runs for sustained heavy loads may require larger AWG sizes.

Pros & Cons

Pros

• OFC stranded conductors for improved conductivity and corrosion resistance under repeated flexing.
• Durable PVC jacket resists oil, water, and acid for outdoor and industrial use.
• Flexible 200 ft bulk length reduces the need for connections on larger setups.
• Wide operating temperature range keeps insulation stable in extreme conditions.

Cons

• Contains four current-carrying conductors only, so there is no separate ground conductor included.
• As 18 AWG, it is not suitable for long runs carrying very high continuous currents where thicker gauge cable is required.

Our Verdict

The 18/4 SJOOW 200 ft cable is a practical choice for anyone needing a flexible, chemically resistant 4-conductor portable cord for industrial, marine, or temporary power use. Its oxygen-free copper strands and robust PVC jacket deliver long-term value when a separate ground is not required and the load fits 18 AWG capacity.

Frequently Asked Questions

Does this cable include a separate ground conductor?
No. This product contains four current-carrying conductors only and is not a 4+1 style cable with a separate grounding conductor.

Is this cable suitable for outdoor and marine use?
Yes. The PVC jacket resists oil, water, and acid and the rated temperature range supports outdoor and marine deployments.

Can this be used for heavy continuous motor loads?
It is suitable for many portable motor and equipment leads, but for long runs or very high continuous currents consider a larger gauge cable to avoid voltage drop and overheating.
