Camco’s PowerGrip 25-foot RV extension cord, model 55191, is a 30-amp cord rated for 125 volts and 3,750 watts with 10-gauge conductors. It adds reach between a compatible campground pedestal and a 30-amp RV cord—but it does not increase the electrical service available.

Why a dedicated RV cord matters
A 30-amp RV circuit is different from an ordinary household extension cord. The connector shape, conductor size and rating must suit the load. Using a light household cord for a high-demand RV setup can create excessive voltage drop and heat. The PowerGrip is built for the 30-amp RV application identified by its label.
The 25-foot length is useful when a pedestal is located behind the site or on the wrong side of the RV. It also provides a backup when the primary route cannot reach without tension. More length creates more voltage drop, so extension cords should solve a real reach problem rather than become the default when the standard cord already connects safely.
Pre-purchase checks
- Confirm your RV has 30-amp, 125-volt service and identify both connector styles.
- Verify model 55191 and the included male and female ends on the retailer listing.
- Measure the route without stretching the cord across traffic or sharp edges.
- Make sure your storage compartment can hold a heavy 10-gauge cord.
- Plan how you will keep connections off wet ground and protected as directed.
Safe campsite use
Turn off the pedestal breaker before connecting or disconnecting. Inspect the plug blades, receptacle, jacket and strain relief for burns, looseness, cuts or corrosion. Fully deploy the cord rather than leaving a tightly coiled bundle that can retain heat. After power is applied, monitor for abnormal warmth or odor and disconnect if anything seems wrong.
An adapter changes the plug arrangement; it does not create more capacity. If a 30-amp RV is connected to lower-rated service, reduce loads to match the source and adapter. Air conditioning, water heating and cooking appliances can quickly exceed a limited connection when used together.
Our buying take
The 25-foot PowerGrip is a sensible emergency and odd-site accessory for a properly maintained 30-amp RV. It is most valuable when used occasionally and inspected carefully. Buyers with 50-amp RVs need a cord specifically rated and configured for that service rather than this model.
