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.

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.

One consideration is that at nearly 19 pounds, it’s somewhat heavy, so it might be less convenient for frequent moving.
