MECMO 50A Y Splitter NEMA 14-50P to 2x14-50R, 3 ft ETL Listed Heavy-Duty RV & EV Adapter

This heavy-duty 14-50 Y-adapter is built for RVers, EV owners, and generator users who need to share a single 50-amp, 125/250V outlet between two devices — for example an RV and an electric vehicle or two campsite accessories. Molded construction with thick copper conductors and an ETL listing prioritizes durability and safety for indoor and outdoor use. The cord follows UL-style wiring standards and offers a compact three-foot reach for neat setups at campsites, garages, and generator stations.

How does this splitter let me power two devices from one 50A outlet?

The MECMO Y-splitter features one NEMA 14-50P male plug that splits into two NEMA 14-50R female outlets, effectively duplicating a single 50A feed. It supports 125/250V and is rated to the full 50 amps of the source when used within its electrical limits.

• One 14-50P male to two 14-50R female connections
• Rated for 125/250 volts and a 50 amp maximum per plug configuration
• Works with Level 2 EV chargers (Tesla models included) and 50A RVs
• 3-foot cable length for tidy, short-run connections

Is this adapter safe for outdoor use at campsites and with generators?

Yes — the cable uses heavy-duty PVC jacketed wiring and UL-style STW conductors, and the assembly is ETL listed for safety. While the connector is built for outdoor-rated receptacles found on generators and RV park pedestals, standard outdoor common-sense precautions still apply (dry connections, strain relief, and proper grounding).

• ETL listed for verified safety compliance
• STW 6 AWG x3 and 8 AWG x1 copper conductors for dependable current flow
• Molded plug and jacket resist weather and abrasion
• Use with properly rated outdoor outlets and covers

Will this work with my EV (Tesla Model 3/S/X/Y) and a 50A RV at the same time?

The Y-adapter provides two NEMA 14-50 outlets suitable for Level 2 EV charging and 50A RV power cords, but the total available power depends on your supply. If your source is a true 50A, both devices can connect, but you must manage load distribution so you don’t exceed the source ampacity.

• Compatible with Level 2 EV chargers that accept 14-50 plugs
• Fits Tesla charging setups using a NEMA 14-50 adapter
• Connects RV shore power plugs without modification
• Monitor combined load to avoid tripping breakers

How durable and easy to use is the MECMO splitter?

The adapter uses thick copper conductors with individual insulation and a robust PVC outer jacket to withstand frequent plugging and outdoor use. The molded connectors give a secure fit into standard 14-50 sockets, and the short three-foot length reduces cable clutter and tripping hazards.

• 6/3 and 8/1 AWG copper wiring for reliable current capacity
• Molded male and female ends for secure connections
• 3-foot cord for compact setups and minimal tangling
• Designed for indoor and outdoor rated outlets

Who this is for: The MECMO 50 Amp Y Splitter is designed for RV owners who want to add a second 50A connection, EV drivers who need occasional campsite charging alongside RV power, and anyone using generators or campground pedestals where one 50A outlet must serve two devices. It’s ideal for short, straightforward hookups where a durable, ETL-listed, easy-to-use adapter is required — provided you observe the electrical load limits and local codes.
