NEMA L14-30P to 14-50R RV Generator Adapter，4 Prong 30A to RV/EV 4 Prong 50A Twist Lock Power Converter for RV, Trailer, Camper, EV, and Tesla Level 2

L14-30P to 14-50R Adapter: Converts a generator’s 30A 4-prong locking outlet (NEMA L14-30P male) to a 50A 4-prong RV/EV outlet (NEMA 14-50R female) for RVs, trailers, campers, and most Level-2 EV chargers. Electrical Ratings (Generator-Side Limits): 30A, 125/250V; up to 3,750W at 125V or 7,500W at 250V. Shape converter only—does not increase a 30A circuit to 50A. For continuous loads, set charging/current ≤24A. Generator Plug Details: NEMA L14-30P, 4-wire (Hot-Hot-Neutral-Ground) locking plug fits common 30A generator receptacles and provides 120/240V to a 14-50 connection. 14-50R Outlet with Grip: Heavy-duty NEMA 14-50R receptacle with easy-pull handle; accepts standard 14-50 RV cords and portable EVSEs; 125/250V compatibility. Durable & Safe Build: Molded body, copper conductors, flame-retardant jacket, strain relief; designed for RV/EV use. Follow generator and EVSE instructions; some generators may require neutral-ground bonding. Not for back-feeding a home panel. Power your RV or Level-2 EV charger from a generator with this heavy-duty NEMA L14-30P to 14-50R adapter. On the generator side, the locking L14-30P (30A, 4-prong) plug connects to common 120/240V 30-amp generator outlets. On the device side, the 14-50R (50A, 4-prong) receptacle accepts standard RV cords and most portable EVSEs (including Tesla units that use a 14-50 plug). It’s a shape/convenience converter only—it does not upgrade a 30A circuit to 50A—but it lets you safely use your existing 14-50 equipment when a 30A generator is all that’s available. Built for the field, the adapter features molded strain relief, copper conductors, and a flame-retardant jacket for reliable performance at campsites, job sites, and during outages. The easy-grip 14-50R handle makes plugging and unplugging simple, even with gloves on. Key Specs & Compatibility: 1. Interfaces: NEMA L14-30P (male) → 14-50R (female) 2. Electrical Ratings: 30A, 125/250V; up to 3,750W @125V or 7,500W @250V (limited by your generator) 3. Wiring: Hot–Hot–Neutral–Ground (120/240V split-phase) 4. Use With: RVs, trailers, campers, and portable EV chargers/EVSEs with a 14-50 plug (incl. many Tesla mobile chargers) Safety Notes (Read Before Use): 1. This is a 30A circuit. For continuous loads, set EV/charger current to ≤24A (80% rule). 2. Actual power depends on your generator’s rating; reduce current if the generator bogs or trips. 3. Some generators have floating neutral; your RV/EVSE may require neutral-ground bonding per the device manual. 4. Do not back-feed a home electrical panel.
