VASTHOME 50 Amp Twist-Lock Adapter SS2-50P to 14-50R — 50A 125/250V, Pure Copper with Molded Grip

The VASTHOME 50 Amp Twist Lock Adapter converts a NEMA SS2-50P twist-lock feed to a 14-50R receptacle, delivering a durable 50A, 125/250V connection for RVs, generators, welders, dryers, and EV equipment.

This heavy-duty adapter bridges two common 50-amp interfaces so you can use existing cords or appliances with a twist-lock power source. Built with 100% pure copper conductors, thick STW cable, and a molded grip handle, the adapter is engineered for secure electrical contact, flexible placement, and repeated use in demanding outdoor or workshop settings. It supports up to 12,500W at full 250V and up to 7,500W at 125V, making it a practical solution for many mobile power needs.

How does this adapter keep a secure electrical connection?

The SS2-50P twist-lock plug holds tight under vibration and movement, while the 14-50R female end accepts standard 50A appliance cords. The internal design uses pure copper conductors to reduce resistance and heat buildup.

• Twist-lock plug prevents accidental disconnection under load
• 14-50R female socket accepts common 50A appliances and cords
• 100% copper conductors for consistent conductivity
• STW cable resists oil, water splashes, and bending stress

Will this work between my generator and my RV or dryer?

Yes — the adapter is specifically designed for generator-to-appliance and generator-to-RV connections where a twist-lock source must feed a straight-blade 14-50 cord. Check your equipment ratings and local electrical codes before use.

• Accepts 125/250V input at 50 amps for broad compatibility
• Output supports up to 12,500W at 250V and 7,500W at 125V
• Compatible with dryers, welders, EV chargers, generators, and RV power cords
• Use with appropriate breakers and grounding practices only

How portable and durable is the cable assembly?

The molded assembly keeps the cable and plugs secure, while the 10.25" flex cable and overall 21" length balance reach with compact storage. Heavy-gauge 6/3 + 8/1 AWG STW wiring and robust strain reliefs extend service life in outdoor and workshop environments.

• 10.25" (26 cm) cable between connectors for flexible placement
• Total length ~21" (53 cm) — compact but practical
• 6/3 + 8/1 AWG STW cable: 3 power conductors + 1 ground conductor
• Rigid grip handle for easy plug insertion and removal

Do I need any tools or wiring changes to use it safely?

No internal rewiring is required; this is a plug-and-play adapter. However, you should verify that plugs, cords, and connected devices share the same 50A rating and that your generator/breaker provides proper protection.

• Pre-assembled — no field wiring needed
• Confirm matched 50A ratings and compatible voltages before use
• Always connect through appropriate breakers and ground connections
• Inspect plugs and cable for wear before each use

Who is this for: This VASTHOME adapter is intended for RV owners, contractors, and makers who need a rugged, short-run connection between a NEMA SS2-50P twist-lock power source and a standard 14-50R 50A cord. It's ideal for temporary power setups at campsites, job sites, mobile workshops, and for owners who want a reliable, low-resistance adapter that simplifies connecting generators, dryers, welders, and certain EV charging equipment. It is not a substitute for fixed wiring or permanent installations — always follow local electrical codes and safety practices.
