Yomiuwo 50 Amp NEMA 14-50 EV Outlet with Wall Plate – Heavy-Duty Industrial Grade, ETL Listed

Overview

Meet a robust solution for high-power charging needs. The Yomiuwo 50 Amp NEMA 14-50R outlet with wall plate is built for demanding environments, delivering practical reliability without compromising ease of installation. This model emphasizes heat management, secure connections, and a clean, professional finish suitable for home garages, workshops, and RV setups.

Designed to withstand extended charging sessions and frequent use, the unit blends sturdy materials with thoughtful detailing. While not a guaranteed outcome, the design aims to help maintain consistent performance across a range of daily charging scenarios.

Heavy-Duty Build for Extended Sessions

The outlet features a 2.42-inch diameter and weighs about 203.5 g, substantially larger and heavier than many standard models. This added mass—paired with high-quality brass and durable nylon—supports better heat dissipation during longer charging periods, helping to minimize overheating tendencies and voltage dips that can occur with high-power use.

Improved Conductivity with a U-Shaped Clamp

The U-shaped brass clamp provides 3x more wire contact surface than conventional flat terminals. This design enhances conductivity and reduces resistance, a common source of heat in high-current outlets, contributing to steadier power delivery in demanding charging sessions.

Secure, Vibration-Resistant Install

Industrial M4 hex screws with a hex-lock mechanism help maintain constant pressure through thermal cycling and plugging cycles. This setup supports stable connections and minimizes arcing or power loss over time, which is especially helpful in busy garages and workshop environments.

Professional Finish with DIY-Friendly Wiring

The oversized 2.42" stainless steel wall plate is designed to cover 2-gang boxes neatly, delivering a professional finish and complete terminal visibility. Color-coded terminals (X/Hot, Y/Hot, W/Neutral, G/Ground) simplify wiring, reducing setup errors for DIY enthusiasts and professionals alike.

Compatibility, Safety, and Warranty

Designed for 125/250V operation and compatible with #4, #6, or #8 AWG copper wire, the unit supports flexible installation in varied spaces. It is ETL-listed for safety and backed by a 3-year warranty, providing confidence for frequent charging and heavy-duty use. Note: the weatherproof box is not included and must be purchased separately to fit your installation needs.

What You Get

A reliable NEMA 14-50R outlet paired with a sturdy wall plate, ready for DIY installation or professional mounting in the right enclosure. This setup targets home EV charging, RV hookups, and other high-power applications where robust, steady power delivery matters.
