H3JANG EV Charger Adapter Cord — TT-30P to 14-50R 30A→50A, Tesla Gen 2 Compatible, 10 AWG ETL/UL

The H3JANG EV charger adapter cord converts a 3-prong 30A TT-30P dryer outlet into a 14-50R 50A-style receptacle so you can safely charge J1772-compatible EVs and Tesla mobile connectors when a dedicated Level 2 station isn’t available.

This compact, certified adapter is designed for travelers and EV owners who need a temporary way to use campground or RV park TT-30 dryer outlets for Level 2 charging. It is built with 10 AWG conductors, STW-grade insulation, and ETL/UL-listed components to reduce overheating risk and provide dependable connections for Tesla Gen 2 mobile chargers and other J1772-compatible vehicles. Read on for clear answers about compatibility, safe use, and practical features.

How does this adapter let me charge my EV from a dryer outlet?

The cord adapts a 3-prong TT-30P (30A, 125/250V) plug into a 14-50R-style 50A receptacle so you can attach a Tesla Gen 2 mobile connector or other J1772 charging cords. It does not increase circuit capacity — it only converts plug type and provides a safe, temporary connection.

• Connect TT-30P into campground/RV dryer outlet.
• Plug your Tesla Gen 2 or J1772 mobile connector into the 14-50R outlet end.
• Set vehicle charger to maximum 24A continuous draw for safe operation.
• Adapter supports charging where dedicated Level 2 stations are unavailable.

Is this safe to use and what certifications does it have?

The H3JANG adapter uses heavy 10 AWG wiring and STW-grade insulation to limit heat build-up, and its plug and socket carry ETL and UL listings to meet recognized safety standards. Always follow the vehicle manufacturer’s instructions and local electrical codes when using an adapter.

• 10 AWG conductor minimizes voltage drop and overheating.
• STW-grade jacket provides flexible, durable insulation.
• ETL & UL-listed components for verified safety compliance.
• Ergonomic handle and 180° rotating cable for secure connections.

Which vehicles and situations is this adapter compatible with?

This adapter is intended for EV use only and works with Tesla Gen 2 mobile connectors and other vehicles that accept a J1772 plug via a 14-50R inlet. It’s ideal for overnight charging at campgrounds, RV parks, job sites, or other locations that offer TT-30 dryer outlets but lack dedicated EV chargers.

• Compatible with Tesla Model S/X/3/Y and Cybertruck with Gen 2 mobile connector.
• Works with all J1772-compatible electric vehicles when using proper mobile connector.
• Perfect for remote or temporary charging where only TT-30 outlets exist.
• Confirm your charger and vehicle support load-limited charging before use.

How should I set my car and maintain the adapter for best results?

Set your car’s onboard charger to a maximum of 24 amps before plugging in; this follows the recommended continuous power draw guideline (30A peak × 0.80 = 24A continuous). Inspect outlets and the adapter for damage before each use and store the cord dry and clean to protect insulation and connectors.

• Program vehicle charger to 24A max continuous draw for safety.
• Check receptacles for tight fit and no burn marks before plugging in.
• Keep the 13-inch cord and rotating cable clean and dry when stored.
• If unsure about compatibility, contact H3JANG customer support for help.

Who is this for: The H3JANG TT-30P to 14-50R adapter suits EV owners who need a reliable, portable solution to charge at campsites, RV parks, or remote locations where only a 3-prong 30A dryer outlet is available. It’s not a permanent hardwired upgrade or a device to increase circuit capacity — it’s a certified, temporary converter for travelers and professionals who understand load limits and follow safe charging practices.
