## FAQ

- What is a Tesla NACS charging extension cable? — A NACS extension cable is a male-to-female cord that sits between a Tesla Wall Connector or Mobile Connector and the car's charge port.
- Is this an official Tesla product? — Trfikne makes the cord independently, and it is not a Tesla-branded accessory.
- Does this replace my Tesla Wall Connector or Mobile Connector? — The extension adds reach to the charger you already own; it cannot charge on its own.
- Will this cable reach from my garage wall connector to where I park on the street? — Combined reach runs 45 ft with the 21 ft cord and 64 ft with the 40 ft cord, once you count the roughly 24 ft factory cable.
- Does using a third-party cable void my car's warranty? — Vehicle warranties cover the vehicle, not accessories plugged into it, and a compliant NACS extension does not modify the car.
- What comes in the box? — One extension cord with a molded NACS male end and a matching female socket, plus a premium carry and storage bag.
- What amperage, voltage, and wattage does the cable handle? — Both lengths are rated at 50A, 240V, and 12kW continuous.
- What wire gauge does each length use? — The 21 ft cord runs 12 AWG copper and the 40 ft runs 13.5 AWG, both rated for a continuous 50A load.
