Gociean 30A to 50A RV Adapter TT-30P to SS2-50R 18" — ETL-listed, 10 AWG Copper, Twist-Lock

Gociean's 30 Amp to 50 Amp RV adapter converts a TT-30P 30A shore power plug to an SS2-50R 50A twist-lock inlet so you can safely run 50A RV equipment from a 30A campsite without hauling a heavy 50A cord.

This compact 18-inch adapter closes the gap between campsite power standards by providing a secure, ETL-listed connection from a NEMA TT-30P male to a NEMA SS2-50R female twist-lock. Built with full 10 AWG copper conductors, an STW-rated jacket and a 90-degree ergonomic grip on the female end, it’s designed to deliver reliable outdoor power while minimizing strain on cords and inlets.

How does this adapter let me use 50A RV gear at a 30A hookup?

The adapter routes the available 30-amp feed into a 50-amp receptacle form factor, allowing devices with a 50A plug to connect to a 30A source. It does not increase available amperage; it simply adapts the plug style for compatibility.

• Converts NEMA TT-30P (30A) male to NEMA SS2-50R (50A) female twist-lock.
• Rated for 114–126V, 3750W maximum load at 30A.
• 18-inch length keeps connections neat without extra cord bulk.
• Twist-lock female secures plug for vibration resistance.

Is this adapter safe for outdoor RV use?

Yes — the adapter is ETL listed and constructed with 10 AWG pure copper conductors inside an STW jacket and flame-retardant PVC sheath to withstand outdoor conditions. The molded housing and strain-relief design reduce wear at connection points.

• ETL tested to applicable safety standards for added assurance.
• 10/3 gauge copper wiring for better conductivity and lower heat.
• Durable STW jacket resists moisture, abrasion and UV exposure.
• 90-degree ergonomic female handle reduces bending stress on inlets.

Will this prevent damage to my RV power inlet or cords?

The adapter’s 90-degree female grip keeps the cord profile flat against the RV side, lowering mechanical strain and reducing the chance of pulling or twisting that can damage connectors. While it improves handling and protection, always observe amperage limits and use proper cord management.

• 90° design lets the cord lie flat to reduce strain on the inlet.
• Molded ends and strain relief limit flex and connector fatigue.
• Twist-lock action secures the plug against vibration and accidental unplugging.
• Compact size removes need to carry heavy 50A extension when unnecessary.

Who is this for: Gociean’s adapter is intended for RV owners, campers and service technicians who need a compact, durable way to connect 50A appliances or shore-power cords to a 30A campsite without dragging a bulky 50A cable. It’s ideal when you want a secure, ETL-listed connection, cleaner cord routing, and a lightweight solution for occasional use — but it’s not a power booster: observe the 30A maximum load when planning appliance use.
