10 Best Cord For Generators 2026 in the United States

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 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.

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.
