Buying Guide
Key purchase considerations help identify which RV power cord best fits your setup and location:
- Length and amperage: Choose length based on campsite layout and electrical service. Common options include 15–30 ft for travel trailers and 25–50 ft for motorhomes, with 30A or 50A ratings depending on your RV’s inlet.
- Connectors: TT-30P to L5-30R connectors suit many RVs and generators. Locking connectors add stability and corrosion resistance in windy or outdoor environments.
- Jacket material and rating: STW jackets with 10/3 or 6/3+8/1 copper conductors offer durability and weather resistance. Look for outdoor-rated, flame-retardant PVC sheaths and temperature ratings suitable for outdoor use.
- Safety features: LED power indicators help confirm power presence; disconnect handles reduce the risk of shock during plugging/unplugging; ETL/cETL listings indicate third-party safety testing.
- Durability and weather resistance: Weatherproofing, abrasion resistance, and flexibility in cold weather matter for year-round camping. A robust sheath and strong strain relief contribute to cord longevity.
- Portability versus capacity: Longer cords provide reach but are heavier. Consider a balance between portability and the needed amperage to support RV appliances and air conditioning.
- Maintenance and organization: Some cords include a cord organizer or storage features, which helps prevent tangling and wear when stored.
In evaluating options, compare not just length and amperage but also build quality, safety certifications, and practical features like LED indicators and ergonomic grips. For heavier RVs or sites with generator hookups, a longer 50A option may be necessary, while smaller setups can rely on 15–25 ft 30A cords.
