This is a 75 ft 50 amp extension cord with NEMA 14-50 plugs on both ends, built from 6/3+8/1 gauge STW cable and ETL/cETL certified. It lets you move a 14-50 outlet further from an RV pedestal or a Level 2 EV charger without adding an adapter. The heavy jacket and thick conductors make it durable but stiff and hard to route around tight corners. Owners report no heat at the connectors when charging an EV, which is the main thing to want from a cord at this amperage.
