10 Best Cord For Generators 2026 in the United States

The Camco Power Grip 30-foot extension cord is a solid choice for RV owners or electric vehicle users needing a reliable 50-amp power connection. Its 6/3 + 8/1 gauge copper wires ensure strong and efficient electrical conductivity, making it capable of handling up to 12,500 watts at 125/250 volts. The cord is long enough to offer some flexibility in placement without being cumbersome. With a Type B plug format and standard male and female locking connectors (NEMA 14-50P and NEMA 14-50R), it fits well with many RVs and EV charging setups.

The heavy-duty, heat-resistant PVC jacket adds protection against outdoor elements like heat and wear, which is important if you plan to use it in various weather conditions. The 90° angled heads and secure grip handles make plugging and unplugging easier and reduce strain on the connections, helping to prevent damage over time. Additionally, the cord comes with a convenient adjustable organizer strap for easy carrying and storage. While it only has a single outlet, this is typical for RV extension cords and matches the intended use. One minor note is that the cord weighs over 22 pounds, which might be a bit heavy for some users to carry frequently.

This cord is well suited for anyone needing a durable, flexible, and safe 50-amp extension cord for their RV or EV, especially if they want a product that can handle outdoor conditions and provide peace of mind with certifications like ETL and UL.

The DuroMax XP5050GC is a solid choice if you need a heavy-duty generator cord, especially for home power backup. It features a thick 6-gauge wire, which is excellent for safely handling a high 50-amp load without overheating. At 50 feet long, it offers good reach to connect your generator to your home transfer switch or other appliances. The cord uses a NEMA 14-50 plug type, which is common for 240V generators, making it compatible with many home generators.

Its sturdy STW jacket protects against moisture, abrasion, and extreme temperatures, so it holds up well outdoors in different weather conditions. The reinforced blades and grounded plugs add safety and durability, reducing the risk of damage during regular use. On the downside, the cord is quite heavy (39 pounds), which might make it less convenient to carry around frequently. Also, it doesn’t include the inlet box or transfer switch, so you need to have those ready to connect.

This cord is most suitable for homeowners looking for a robust, weather-resistant cable to connect a 240V generator to their home's power system safely and efficiently, though its size and weight could be a consideration if portability is important.

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.
