Camco Power Grip 25-Ft 50 Amp RV Extension Cord - Rated for 125/250 V/12,500 W - Features Copper 6/3 + 8/1-Gauge Wires for Superior Conductivity & Coated w/Heat-Resilient PVC (55542)
Most important from
6315 reviews
The Camco Power Grip 25-foot 50 Amp RV extension cord is a solid choice for anyone needing reliable power connections for RVs or electric vehicles. It features heavy-duty 6/3 and 8/1 gauge copper wires, which means it can safely handle high power loads up to 12,500 watts at 125/250 volts without overheating. The 25-foot length offers enough reach to plug your RV or EV into a power source without hassle.
One big plus is the cord’s weather-resistant, flame-retardant PVC jacket that guards against outdoor wear, making it durable for camping and outdoor use. The 90-degree head on the plug reduces strain on the connection points, helping prevent damage over time. It also includes handy grip handles to make plugging and unplugging easier and safer. This cord has a single 50 amp plug and outlet, which is typical for RV power needs but limits you to one connection at a time.
Although it is somewhat heavy, weighing over 18 pounds, the adjustable organizer and carrying strap assist with storage and transport. Certified to meet safety standards (ETL listed), this cord suits RV owners and EV users looking for a dependable, well-built extension cord that stands up to outdoor conditions. If multiple outlets or a longer reach are necessary, more specialized options should be considered.

Camco Power Grip 25-Ft 50 Amp RV Extension Cord w/90° Locking End - Rated for 125/250V & 12,500W - Features Threaded Locking Ring for Weatherproof Connection & Coated w/Heat-Resilient PVC (55574)
Most important from

The Camco Power Grip 25-foot extension cord is a solid choice for RV owners or electric vehicle users needing a reliable 50-amp power connection. It comes with heavy-duty, locking marine-style connectors rated at 125/250 volts and can handle up to 12,500 watts, which is plenty for most RV power needs. The cord’s 6/3 + 8/1 gauge wiring is all copper, ensuring good electrical conductivity and safety. It features a heat-resistant and flame-retardant PVC jacket, making it sturdy enough for outdoor use and protecting it against wear and weather.
The 90-degree locking plug ends reduce strain on the cord and connection points, which helps avoid damage during use. Additionally, the cord includes a handy carrying strap for easier transport and storage. One consideration is that at nearly 19 pounds, it’s somewhat heavy, so it might be less convenient for frequent moving. Also, the cord has just one outlet type—designed specifically for 50-amp RV or EV connections—so it’s not meant for multiple devices or different plug types.
If you need a strong, weather-resistant extension cord tailored for RV or EV power, this Camco model provides dependable performance and safety features, though it’s less flexible for other uses.

Generac 6390 50-Feet 50-Amp Generator Cord - Secure and Reliable Power Connection , Black
Most important from
74 reviews
The Generac 6390 is a 50-foot, 50-amp generator cord designed to provide a secure and reliable connection between your generator and transfer switch or power inlet box. Its standout feature is the weather-resistant thermoset rubber construction, which keeps the cord flexible even in cold conditions and protects it against harsh outdoor environments. This makes it a solid choice if you need a durable cord for various weather situations.
The cord uses a male NEMA 14-50 plug and a female CS6364 twist-lock connector, ensuring a snug and safe fit that prevents accidental unplugging—a key point if you want uninterrupted power during use. It’s compatible with many Generac transfer switches and power inlet boxes, making it a convenient pick if you own or plan to use Generac equipment. It carries a UL listing, reassuring you about safety and quality, and comes with a 2-year limited warranty.
The cord weighs 32 pounds, which might make it less convenient to handle or transport compared to lighter alternatives. Also, while it’s great for Generac users, those with other generator brands should double-check compatibility since the plug type and amperage are specific. If you prioritize a weatherproof, reliable cord for a 50-amp generator setup, especially with Generac gear, this cord is a dependable option. Just be ready for its heavier weight and confirm it fits your generator system before buying.
