Nilight EV Adapter Cord NEMA 14-30P to 14-50R 12in — 10 AWG 30A Level 2 J1772 Charging Adapter

A compact Nilight adapter cord that converts a NEMA 14-30 30-amp dryer outlet into a NEMA 14-50 50-amp EV charging inlet for Level 2 J1772 chargers.

This heavy-duty 12-inch Nilight EV adapter lets owners use common 4-prong dryer-style receptacles to connect Level 2 J1772 charging equipment that expects a 14-50R inlet. Built with full 10 AWG stranded copper conductors and a flame-retardant STW PVC jacket, the cord balances flexibility and durability for home garage or covered outdoor use. It’s designed for charging at up to 30 amps from a 14-30R receptacle; verify your outlet type and charging equipment compatibility before use.

How will this adapter fit my home charging setup?

The Nilight adapter has a NEMA 14-30P male plug (30A) that connects to typical 4-prong dryer outlets and a NEMA 14-50R female inlet (50A) for your EV charger. It does not alter the outlet’s circuit rating — your actual charging current should be set to match the 30-amp source to avoid tripping breakers or overheating.

• Plugs: NEMA 14-30P (male) to NEMA 14-50R (female)
• Length: 12 inches — short, direct connection for garage use
• Electrical rating: rated for 125/250V, 3750W, typical use at 30A
• Intended for Level 2 J1772 EV chargers; not a dryer or RV adapter

Is this cord safe and built to last in household conditions?

Yes — Nilight uses 100% pure stranded copper 10 AWG conductors for reliable conductivity and an STW-rated, flame-retardant PVC jacket for abrasion and weather protection. The construction promotes flexibility while protecting the wires from everyday garage hazards and moderate outdoor exposure.

• Full 10 AWG stranded copper for higher conductivity and flexibility
• STW jacket with flame-retardant PVC for heat and abrasion resistance
• Weather-resistant outer sheath suitable for rain, wind, and mild snow
• Short run reduces voltage drop compared with long extension alternatives

What charging performance should I expect when using this adapter?

The adapter itself is rated for higher current, but when plugged into a 14-30 outlet you should limit charging to the outlet’s circuit capacity — typically 30 amps. Set your EV or EVSE to the appropriate current to avoid prolonged heat buildup in the plug or nuisance tripping of the home circuit breaker.

• Set charge rate to 30A or lower when using a 14-30R receptacle
• Rated power up to 3750W based on 125/250V specification
• Short cord length minimizes temperature rise from long runs
• Check vehicle/charger settings to match source capacity

Will this adapter work with my existing EV charger and outlet?

It’s compatible with Level 2 J1772 chargers that plug into a 14-50 inlet, allowing those chargers to connect to a 14-30 household outlet instead. Confirm that your home receptacle is a NEMA 14-30R and that you adjust the EVSE or vehicle charging current appropriately to the circuit’s rating.

• Compatible with J1772 Level 2 charging equipment expecting 14-50R
• Not suitable as a direct replacement for dedicated dryer or RV wiring
• Always inspect outlet and adapter for damage before use
• Consult a licensed electrician for any outlet or circuit concerns

Who is this for: The Nilight 30A-to-50A adapter is ideal for EV owners who already have a 4-prong NEMA 14-30 dryer-style outlet in a garage or covered parking area and want a short, robust adapter to use an existing Level 2 J1772 charging unit without rewiring. It’s also useful for DIYers or homeowners who prefer a compact, heavy-gauge cord for temporary or occasional charging where a permanent 14-50 installation isn’t available. Do not use this as a permanent substitute for proper circuit upgrades — consult an electrician when in doubt.
