Nilight EV Adapter Cord NEMA 10-30P to 14-50R 12in — 30A to 50A 10 AWG Copper, STW Jacket

Nilight EV Adapter Cord converts a 3-prong NEMA 10-30 dryer outlet into a 14-50R receptacle so you can safely charge a Level 2 J1772 EV at up to 30 amps.

Many homes still have legacy 3-prong dryer outlets (NEMA 10-30). Instead of costly rewiring or waiting for a dedicated 14-50 circuit, this compact Nilight adapter provides a practical solution: a heavy-duty 30A to 50A adapter cord wired with full 10 AWG copper conductors and a rugged STW jacket. It’s designed for short, garage or driveway use to let J1772 Level 2 chargers draw power from a NEMA 10-30R receptacle while remaining mindful of the outlet’s 30 amp rating.

How does this adapter let me charge an EV from an old dryer outlet?

The adapter plugs a NEMA 10-30P three-prong male into your existing dryer receptacle and presents a NEMA 14-50R female outlet for your EV charger plug. It does not change the circuit’s capacity—use it to limit the charger to 30 amps or less.

• Wiring: 3 × 10 AWG stranded pure copper conductors for good conductivity.
• Ratings: 30A input, 14-50R female output, 125V, 3750W rating.
• Length: 12 inches—compact for garage/near-outlet use.

Is this adapter safe and built to handle weather or repeated use?

Nilight constructed the cord with stranded 10 AWG copper and an STW thermoplastic jacket that’s flame-retardant and heat resistant. The heavy-duty PVC sheath protects the cable from moisture and abrasion during typical outdoor or garage conditions.

• Material: 100% pure copper conductors for lower resistance and flexibility.
• Jacket: Heat-resilient, flame-retardant PVC for weather resistance.
• Durability: Resists wind, rain, snow and physical wear in short-run installations.

Will this adapter work with my EV charger and charging routine?

Yes, if your EV charger uses a J1772 Level 2 connector and you can set or limit its draw to 30 amps or less. This adapter is intended to let you use a 3-prong dryer outlet as a temporary or occasional charging source—not as a permanent replacement for a dedicated EV circuit.

• Compatibility: Works with Level 2 J1772 chargers; not compatible with RV or dryer appliances.
• Limitations: Do not exceed the outlet’s 30A capacity—adjust charger settings accordingly.
• Use case: Ideal for occasional home charging or emergency situations when a 14-50 outlet isn’t available.

Who is this adapter for? The Nilight 30A-to-50A adapter cord suits EV owners who have legacy NEMA 10-30 dryer outlets and need a short, rugged solution to run a Level 2 J1772 charger at or below 30 amps. It’s for homeowners or renters seeking a lower-cost, temporary charging workaround—those who understand this does not upgrade the circuit’s capacity and will manage the charger’s current accordingly. If you want a permanent fast-charging solution, consider installing a dedicated 14-50 or 14-30 circuit by a licensed electrician.
