10 Best Cord For Generators 2025 in the United States

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.

This 25-foot generator extension cord from Kohree is designed to handle heavy-duty power needs with a 50 amp, 6/3 plus 8/1 gauge cable, suitable for 125/250 volts.

The dual functionality is a nice bonus: you can use it either as a generator extension cord or, by unplugging a pin, as an RV power extension cord compatible with many inlet boxes. This flexibility adds value for users with multiple power needs. The cable comes with an organizer for easy storage, which helps prevent tangling.

The cord is fairly heavy at over 20 pounds, which might make it less convenient to carry around frequently. Also, it has a single outlet configuration, so if you need to power multiple devices simultaneously, you might require additional adapters or cords.

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.
