Portvoi 50A NEMA 14-50 Y Splitter Adapter — 4-Prong to Dual 14-50R, 3ft Cord, ETL-Certified

The Portvoi 50 Amp NEMA 14-50 Y Splitter converts one 4-prong 250V 50A plug into two independent NEMA 14-50R outlets for flexible EV, RV, and generator power.

When you need to feed two devices from a single 50A supply—whether it’s an RV campsite pedestal, a portable generator, or a 50A EV charger—this Y-style adapter provides a safe, heavy-duty solution. Built with robust copper wiring and ETL certification, the splitter is engineered for frequent outdoor use, easy handling, and predictable performance in camping, mobile living, and backup power scenarios.

How does this splitter manage two high-current devices at once?

The Portvoi splitter divides a single 50A 250V feed into two 14-50R receptacles, enabling either simultaneous or alternating use depending on your setup. It does not increase the total available amperage beyond the source rating, so circuit limits still apply.

• Converts one NEMA 14-50P to two NEMA 14-50R outlets.
• Supports Level 2 EV charging and RV power when source capacity allows.
• Maintains a 50A total draw — avoid exceeding the supply or generator capacity.
• 3-foot cord length for practical reach without excess slack.

Is it safe for outdoor and generator use?

Yes — the adapter is assembled with durable STW-rated copper conductors and housings designed for outdoor handling, and it carries ETL standard certification. Safe operation still depends on correct connection practices and not overloading the upstream breaker or generator.

• 6/3 + 8/1 gauge STW copper wiring reduces heat and voltage drop.
• ETL certified to meet recognized electrical safety standards.
• Ergonomic grip handles simplify plugging and unplugging outdoors.
• Keeps connections stable for camping, mobile, and backup power.

Will this work with my EV charger or RV power cord?

The splitter is compatible with equipment that uses a standard NEMA 14-50R inlet, including many EV mobile chargers (such as Tesla and other Level 2 chargers) and RV power cords. Confirm the device’s plug type and the source’s amperage before connecting to ensure compatibility and safe operation.

• Fits typical 14-50R connectors used by many EV chargers and RVs.
• Works for 50A Level 2 charging when supply allows.
• Not a solution to increase supply amperage—only splits an existing 50A feed.
• Useful for sharing generator output between two devices, within generator limits.

How easy is it to use and maintain?

The Portvoi splitter is plug-and-play with molded grips for safe handling and a compact 3-foot length that balances reach and portability. Regular visual inspections and correct storage keep the adapter performing reliably; follow normal electrical safety precautions.

• Molded ergonomic handles for tool-free insertion and removal.
• Compact 3' cord designed for campsite and garage convenience.
• Durable construction resists frequent outdoor use and flexing.
• Inspect for wear, keep dry, and store indoors when not in use.

Who is this for? The Portvoi 50 Amp Y Splitter suits RV owners, EV drivers with portable chargers, and anyone using portable generators who needs to feed two NEMA 14-50 devices from a single 50A source. Choose this adapter if you want a rugged, certified, and easy-to-use way to share a 50A supply between two compatible devices while observing your source’s amperage limits.
