VEVOR 75 ft 50A Generator Cord vs VEVOR 75 ft 50 Amp RV Extension Cord

Both are 75 ft, 6/3 + 8/1 STW cords from VEVOR, so the wire and jacket are effectively the same. The real split is the plugs. Cord A ends in a locking SS2-50R/CS6364 connector, which is the standard inlet on many RVs, transfer switches and shore-power boxes, and it handles up to 12,500W. Cord B ends in a plain NEMA 14-50R and is ETL listed, with an LED indicator, a handle and a 15A adapter. Buy A if you need a twist-lock connection; buy B if you want a certified cord with a standard 14-50 outlet and a light.

• Choose the VEVOR 50A locking cord if your inlet or transfer switch takes a CS6364 or SS2-50 twist-lock plug and you want a connection that will not pull loose.
• Choose the VEVOR 75 ft RV cord if you need a NEMA 14-50R outlet, want ETL listing and an LED power indicator, and value the molded handle and 15A adapter.
