RVGUARD RV Extension Cord 100 ft — 25A TT-30, Weather-Resistant 10/3 STW with Storage Bag

The RVGUARD 25 Amp 100 Foot RV Extension Cord is a heavy-duty, weather-resistant power cable with TT-30 connectors designed to deliver safe, reliable shore power for RVs up to 25 amps over long runs.

When you need to bridge long distances between your RV and a pedestal, this 100-foot cord balances reach and durability while minimizing handling stress. Built with a 10/3 gauge STW jacket, molded strain reliefs and ETL/cETL approval, it’s intended for seasonal campsite setups, overflow parking, and temporary outdoor power where convenience and safety matter.

How much power can this cord safely carry at 100 feet?

Rated as a 25 amp extension with standard 30A TT-30 male and female connectors, this cable is designed for loads up to approximately 3,175 watts. Keep in mind that electrical resistance grows with length, and long runs can reduce available current compared with shorter cords.

• Electrical rating: 25 amp nominal with NEMA TT-30P (male) and TT-30R (female).
• Maximum listed wattage: about 3,175 W at nominal voltage for the rating provided.
• Note: longer than ~50 ft can cause notable voltage drop—plan loads accordingly.

What features improve durability and user safety?

Construction focuses on weather resistance and mechanical strength. The 10/3 gauge STW jacket resists abrasion and outdoor exposure, while molded strain-relief ends reduce stress at connector junctions to prevent premature failure.

• Heavy-duty 10/3 STW outer jacket for wear and weather protection.
• Molded strain reliefs on both ends to prevent cable breakage at the plug.
• ETL and cETL approvals signal third-party safety testing.
• Disconnect handle designed to keep fingers clear of live contacts during connection changes.

How easy is it to store and handle this 100 ft cord?

Despite its length and gauge, the design includes organization aids so you can stow it without tangles or bulky coils. A dedicated storage bag and reusable strap keep the cord compact and protected when not in use.

• Includes a zippered storage bag that protects the cord from dirt and UV when stored.
• Plastic strap wraps the cord for tidy, compact storage in an RV bay or garage.
• Disconnect handle helps unplug without twisting or excessive pulling on the cable.

Will this cord work with my RV’s shore power connection?

It’s made to interface with the common 30-amp TT-30 shore power inlet found on many RVs and campgrounds. Check your RV’s inlet type and expected load; this cord is specifically configured as a 30A TT-30 male to 30A TT-30 female extension with a 25 amp continuous rating.

• Connectors: standard NEMA TT-30P (male) and TT-30R (female) for 30A RV inlets.
• Recommended for RVs wired for 30A shore power needing a long extension run.
• Not intended to convert voltage or change amperage capacity of the source pedestal.

Who is this for? The RVGUARD 25 Amp 100 Foot RV Extension Cord is aimed at RV owners, seasonal campers, and park operators who require extended reach without sacrificing durability. It’s a practical choice for people who frequently park further from pedestals, set up in large campgrounds, or need a rugged spare cord for trips and storage. If you need shorter runs, keep in mind that resistance and voltage drop decrease with cable length; for permanent or high-draw applications consider matching cable gauge and length to your specific power requirements.
