Kanayu 50A 14-50P to 14-50R RV/EV Extension Cord — 3ft Heavy-Duty Waterproof STW with Grip Handles

This compact 3-foot cord pairs a molded NEMA 14-50P plug with a matching 14-50R receptacle, built for outdoor use with UV-resistant, flame-retardant materials and a waterproof jacket. ETL listed and constructed with 100% pure copper conductors and a flexible STW jacket, it’s intended to provide dependable shore power or Level 2 charging where a short, durable connector is needed.

How does this cord handle outdoor conditions?

The Kanayu cord is made for repeated outdoor use: the jacket resists UV, oil and abrasion while the molded ends minimize moisture intrusion. Flame-retardant materials and corrosion-resistant contacts help maintain performance season after season without becoming brittle.

• UV-resistant, waterproof STW outer jacket for weather protection
• Flame-retardant, oil- and abrasion-resistant construction
• Molded plug and receptacle to reduce moisture entry and wear
• 100% pure copper conductors resist oxidation and conduct efficiently

Will this 3ft cord provide enough power for my RV or EV?

Yes — it’s rated for 50 amps at 125/250V, delivering up to 12,500 watts, which meets the typical shore power and many Level 2 EV charging needs. The four-prong NEMA 14-50 configuration supports both 120V and 240V loads when wired appropriately.

• NEMA 14-50P (male) to 14-50R (female) four-prong configuration
• Rated 50A, 125/250V, up to 12,500W
• Suitable for motorhomes, travel trailers and many Level 2 EV charging situations
• ETL listed for safety and compliance verification

What user-friendly features make installation and storage easier?

Kanayu added ergonomic grip handles to the plug and receptacle so you can plug and unplug with less effort while preventing cable strain at the inlet. The cable’s flexibility and included adjustable organizer make coiling, hanging and transporting simple, even in tight storage compartments.

• Ergonomic grip handles for safer, easier connections
• Flexible construction for neat routing around trailer sides
• Adjustable cord organizer included to prevent tangles and ease storage
• Short 3-foot length reduces clutter and keeps the cable close to the inlet

How durable is this cord over the long term?

Durability comes from the combination of 100% copper conductors, molded ends, and tough outer materials that resist the usual outdoor hazards. The design reduces surface oxidation and mechanical strain so the cord stays reliable through repeated hookups and harsh environments.

• Molded plugs and strain-relief to protect internal wiring
• Copper conductors for consistent conductivity and lower heat buildup
• Materials chosen to resist wear, cracking and environmental damage
• ETL listing confirms independently tested safety standards

Who is this for? The Kanayu 3ft 50A 14-50P to 14-50R extension cord is aimed at RV owners, campervan users, and EV drivers who need a short, robust connection between a power source and their vehicle or equipment. It’s also useful for people working on job sites or at outdoor events who want a compact, heavy-duty cable that’s easy to plug, store and rely on in wet or rough conditions. If you need a high-current, weather-ready connector that minimizes cable clutter and strain at the inlet, this cord is a practical choice.
