FAQs
What is a J1772 extension cable and how does it work?
A J1772 extension cable is designed to extend the reach of your existing Level 1 or Level 2 EV charger that uses the SAE J1772 standard connector. It connects between the EVSE (Electric Vehicle Supply Equipment) and your vehicle, allowing greater flexibility when your charging station is located far from your parking space. These cables preserve the full charging speed and safety protocols when properly rated.
What vehicles are compatible with J1772 extension cords?
J1772 extension cords are compatible with all electric vehicles and plug-in hybrids that use the standard J1772 connector, which includes most non-Tesla EVs in North America, such as models from Chevrolet, Nissan, Ford, BMW, and more. Tesla vehicles can also use J1772 extension cords with the appropriate adapter.
How far can a J1772 extension cord extend my charging reach?
J1772 extension cords are available in various lengths, typically ranging from 15 to 25 feet. This allows for flexible charging setups, enabling you to reach your vehicle more conveniently from your charging station, whether at home or in public charging locations.
What power capacity do J1772 extension cords support?
EVDANCE J1772 extension cords support charging capacities up to 50 amps, which is suitable for Level 1 and Level 2 chargers. This means they can handle up to 9.6 kW of power, ensuring efficient and reliable charging for your electric vehicle.
Are J1772 extension cords safe for outdoor use?
Yes, EVDANCE J1772 extension cords are designed with durability and safety in mind. Look for cords that have a high IP rating (e.g., IP66 or higher) to ensure they are waterproof and dustproof, making them suitable for outdoor use in various weather conditions. Additionally, high-quality materials and construction help withstand the elements.
What safety features should I look for in a J1772 extension cord?
When selecting a J1772 extension cord, ensure it includes key safety features such as overcurrent protection, overvoltage protection, and thermal protection to prevent overheating. High-quality cords will often feature components like silver-plated inlets for enhanced conductivity and built-in safety certifications such as UL or CE, ensuring compliance with industry standards.
Are J1772 extension cables safe to use?
Yes, J1772 extension cables are safe if they are UL-listed or tested to industry standards, and if the amperage rating matches or exceeds your charger’s output. Quality cables feature heat-resistant insulation, waterproof connectors, and overcurrent protection, ensuring safe daily use for residential or commercial applications.
Can all electric vehicles use a J1772 extension cable?
All EVs that support the SAE J1772 standard—including models from Ford, Hyundai, Nissan, Chevrolet, and BMW—are compatible with J1772 extension cables. Tesla vehicles can also use them with a J1772-to-Tesla adapter, making this accessory broadly compatible across most EV brands in North America.
Will using a J1772 extension cable reduce charging speed?
A properly rated extension cable will not reduce charging speed. However, using low-quality or undersized cables can result in voltage drop, leading to longer charging times or even EVSE errors. Choose an extension rated for 32A or 40A to match Level 2 charging speeds without compromise.
Do J1772 extension cables support both Level 1 and Level 2 charging?
Yes. J1772 extension cables are compatible with both Level 1 (120V) and Level 2 (240V) chargers. They are designed to handle a range of voltages and amperages (typically up to 40 amps), making them a flexible solution for various EVSE setups, whether at home or work.
