ELEGRP NEMA 10-30P to 14-50R Adapter Cord — 1 ft 30A dryer-plug to 50A EV inlet, 10 AWG STW heavy-duty

The ELEGRP adapter cord converts a 3-prong NEMA 10-30 dryer outlet into a NEMA 14-50 receptacle so you can use a Level 2 portable EV charger without rewiring your home.

This one-foot, heavy-duty converter is designed for homeowners and renters who want faster Level 2 charging from existing dryer outlets. Built with 10 AWG stranded copper conductors and an STW-rated jacket, the cable balances flexibility and durability while minimizing heat build-up during charging sessions. It fits portable EV chargers that require a 14-50R inlet, including Tesla mobile connectors (Gen 2/3), and provides a convenient, temporary alternative to installing a dedicated 14-50 circuit.

How does this adapter let me use Level 2 charging at home?

The adapter mates your home’s NEMA 10-30 dryer plug to a NEMA 14-50-style charger plug, enabling many portable Level 2 units to draw power through an existing outlet. It does not change your breaker or increase the circuit’s capacity; instead, it adapts the plug form so the charger can physically connect.

• Converts NEMA 10-30P (3-prong dryer plug) to NEMA 14-50R (4-prong EV inlet)
• 1-foot length reduces strain and keeps connections close to the wall
• Use with portable Level 2 chargers like Tesla Gen 2/3 mobile connectors

Is this cord safe and what wiring specs should I know?

ELEGRP constructed the cable with 10 AWG stranded copper and an STW thermoplastic jacket to handle continuous charging loads more safely than thinner cords. It’s rated for 30 amps at 125/250V, which supports many Level 2 chargers when the vehicle’s charge current is set appropriately to avoid overloading the circuit.

• 10 AWG stranded copper for better conductivity and less heat
• STW jacket for abrasion and weather resistance
• Molded grips on plugs for secure connections and easy handling

Will this work with my EV and do I need to change settings?

The adapter is compatible with a range of portable Level 2 chargers that accept a 14-50R inlet; many Tesla and aftermarket mobile connectors fall into this category. Because the home circuit remains a 30A dryer line, you should manually limit the vehicle’s charging current—commonly to 24 amps or less—to reduce the risk of tripping your breaker.

• Compatible with Tesla Model 3/Y/S/X with the appropriate mobile connector
• Works with other portable chargers requiring a 14-50R connection
• Set vehicle charge limit to ~24A to match the 30A circuit capacity

How durable is the cable for repeated use and outdoor locations?

The short 1-foot cable is designed to endure regular plugging and unplugging while avoiding unnecessary slack that can tangle or snag. Molded plugs resist wear and the STW jacket protects the conductors from abrasion and exposure, making it suitable for occasional outdoor use when covered or under shelter.

• Short length prevents dragging and reduces mechanical stress on plugs
• Molded connector bodies with grip grooves for repeated handling
• STW-rated jacket resists abrasion, oil, and light moisture exposure

Who is this for: The ELEGRP NEMA 10-30P to 14-50R adapter is intended for EV owners who need a quick, portable way to access Level 2 charging from an existing dryer outlet—especially renters, owners of older homes without a 14-50 circuit, or anyone seeking a temporary charging solution without electrical upgrades. It’s not a replacement for installing a properly sized dedicated circuit when long-term, high-current charging is required; consult a licensed electrician for permanent upgrades.
