50FT 50 Amp RV Locking Extension Cord 14-50P SS2-50R - Heavy Duty

In this review of the 50FT 50 Amp RV Locking Extension Cord, the bottom line is simple: it is for RV owners, campers and anyone needing a long, heavy duty 50-Amp feed in uncertain hookup situations. The reviewer found the cable's single biggest advantage is reliable power delivery over a long run thanks to thick pure copper conductors and low-gauge wiring, which reduces voltage drop and keeps air conditioners and appliances running. It is a practical, no-frills solution when you need dependable, weather-resistant 50-Amp extension power.

Key Features

• Length: A full 50 ft cable gives extra reach for campsites or garages where the power inlet is far from the pedestal.
• High power rating: NEMA 14-50P and SS2-50R connections support up to 12500 Watts at 250 V, suitable for most RV needs.
• Copper conductors: Constructed with 3 x 6 gauge and 1 x 8 gauge 100% pure copper wiring to minimize voltage drop on long runs.
• Safety listings: UL and ETL certification allows use in both the U.S. and Canada with recognized safety standards.
• Weather resistant jacket: Heavy-duty, flame retardant PVC/STW sheath protects the conductors from rain, snow and abrasion outdoors.
• Flexibility: Stranded copper and an STW jacket make the cable flexible enough to coil and store without excessive stiffness.

Who It's For

This cable is best for RV owners, trailer users and caravaners who regularly encounter campsites or parking situations where the built-in cord is too short. It also suits homeowners who need a rugged 50-Amp connection for portable generators or outdoor workshops.

Those who should look elsewhere include buyers who need a very lightweight or compact solution for infrequent short runs, or anyone requiring a different plug configuration than NEMA 14-50P to SS2-50R. If you need specialty shielding or novel connector types, this straightforward heavy-duty cord is not a custom option.

Pros & Cons

Pros

• Solid build quality and heavy-gauge pure copper conductors deliver dependable power with reduced voltage drop.
• Weather-resistant STW/PVC jacket holds up to outdoor use and protects against abrasion and moisture.
• ETL and UL certifications provide recognized safety validation for U.S. and Canada use.
• Flexible stranded wiring makes coiling and storage easier than you might expect for a heavy cord.

Cons

• At 50 ft and with heavy copper, the cable is relatively heavy, which can make handling and storage more cumbersome.
• The product is a utilitarian extension cord with no additional protective carrying case or storage reel included.

Frequently Asked Questions

Can this cord be used outdoors year-round?
Yes. The flame retardant, heat-resilient PVC STW jacket is designed for outdoor use and resists rain, snow and abrasion.

Will voltage drop be a problem at 50 ft?
The use of 6 gauge conductors and an 8 gauge ground limits voltage drop compared with thinner cords, making it a good choice for appliances like air conditioners.

Is this cord certified for use in Canada?
Yes. The cord is UL and ETL certified for use in both the U.S. and Canada.
