GBT to J1772 Adapter
Seamlessly bridge the gap between global EV standards. This professional GB/T to J1772 (Type 1) Adapter enables vehicles with a J-Plug inlet to utilize Chinese-standard (GB/T) AC charging infrastructure. Engineered for the 2026 market, it supports a steady 7.2kW power delivery, ensuring your vehicle’s On-Board Charger (OBC) receives a clean, synchronized signal for efficient Level 2 charging.
-
Stable AC Throughput: Rated for 32A continuous current at 110V–250V AC.
-
Signal Synchronization: Transparently bridges Control Pilot (CP) and Proximity Pilot (PP) protocols.
-
Safety Certified: Built to UL 94 V-0 and CE benchmarks; IP54 weatherproof.
-
Superior Conductivity: Silver-plated copper alloy terminals for 10,000+ mating cycles.
-
Ergonomic Design: Impact-resistant housing with a secure, user-friendly grip.
Professional Overview
As global EV logistics expand, the mismatch between the North American J1772 (Type 1) and the Chinese GB/T standards creates operational friction for importers and expatriates. Our GB/T to J1772 Adapter is designed to provide a “native” charging experience, eliminating the handshake errors common in lower-grade converters.
Drawing on extensive field testing with high-performance 2026 vehicle models, we have optimized the internal pin alignment to ensure zero signal latency. This allows the charging station’s Control Pilot signal to communicate perfectly with your vehicle, ensuring the charging session starts immediately and maintains a stable current flow throughout.

Safety & Trustworthiness
Reliable AC charging at 32A requires precision thermal and electrical management. Our adapter is built with a focus on industrial-grade safety redundancies:
-
Superior Thermal Guard: We utilize 5μm silver plating on all copper contacts, keeping contact resistance below 0.5 mΩ. This prevents heat buildup even during prolonged 7.2kW sessions.
-
Dual Temperature Kill Switch: Integrated sensors monitor the temperature at the contact points. If the adapter reaches 90°C, it triggers a safety signal to terminate the session, protecting your vehicle’s sensitive electronics.
-
Flame Retardancy: The housing is constructed from UL 94 V-0 rated material, meaning it is self-extinguishing and provides a critical layer of safety in the event of an external fault.
-
Rigorous Testing: Every unit undergoes a 2000V AC withstand voltage test and a 10,000-cycle mechanical mating endurance test to ensure long-term durability.

FAQ
-
Can this be used for DC Fast Charging? No. This adapter is strictly for AC Level 2 charging. For DC fast charging, a specialized “Active” converter is required.
-
Is it compatible with my Tesla? Yes, it is compatible with North American Teslas via the J1772 adapter that comes with the vehicle, or by using this to bridge to any J1772-compatible inlet.
-
Is it safe to use in the rain? Yes, with an IP54 rating, the adapter is protected against dust and splashing water, making it safe for outdoor use in diverse climates.
