Which level 2 EV charger connector should you buy? The electric vehicle (EV) market is charged with innovation, presenting consumers with choices that extend beyond the vehicle itself. One key decision for EV owners is selecting the right Level 2 charger connector. In this blog post, we’ll explore the differences between two prominent connectors: J-1772 and NACS (Tesla), helping you decide which one aligns best with your electric journey.
Understanding the J-1772 Connector
The J-1772 connector has been the industry-standard for all non-Tesla car Level 2 charging. This has started to change in 2024 as some auto manufacturers move to the Tesla “NACS” standard.
Advantages of J-1772
Universal compatibility: The J-1772 connector is designed to be universally compatible, offering a standardized charging solution for electric vehicles from different manufacturers. If you own or plan to own multiple EV models, the J-1772 connector ensures consistency in your charging experience. Most manufacturers also include a NACS adaptor just in case you need to charge a Tesla.
Widespread infrastructure: Public charging stations with J-1772 connectors are abundant, providing EV owners with a broad network of accessible charging points. To locate a J1772 charging station for next road trip or daily commute check the US Department of Energy EV Charging Stations locations map.
Versatility: The J-1772 connector is not limited to Level 2 charging. It can also be adapted for Level 1 charging (using standard household outlets) and is often used as the interface for some Level 3 DC fast chargers, offering versatility for various charging scenarios.

Understanding the NACS Connector (Tesla)
The NACS (Tesla) connector, on the other hand, had until 2023 been a proprietary charging connector developed by Tesla for their electric vehicles. While primarily used with Tesla Superchargers, some Tesla vehicles come with an adapter for compatibility with J-1772 connectors. Many auto manufacturers are expected to migrate to the NACS connector over the next five years.
Advantages of the NACS Connector
High-speed charging: The NACS connector is optimized for high-speed charging within Tesla’s Supercharger network. This enables Tesla owners to enjoy rapid charging speeds, making it convenient for long-distance travel.
Seamless integration with the Tesla ecosystem: For Tesla owners, the NACS connector seamlessly integrates with the Tesla ecosystem. It provides a dedicated and efficient charging experience within Tesla’s network of Superchargers.
Tesla-exclusive features: Tesla vehicles may offer exclusive features when charging with the NACS connector, such as over-the-air software updates and real-time Supercharger availability information through the vehicle’s touchscreen.

Choosing the right EV connector for you
How should you decide which connector you need with your EV charger. Consider these ideas:
What type of EV do you have?
If you own or plan to purchase a Tesla vehicle, the NACS connector is the obvious choice for optimized charging within the Tesla ecosystem. For owners of other EV models, the J-1772 connector ensures universal compatibility.
Evaluate charging infrastructure
Before buying an EV, consider the availability of charging stations in your area and along your common routes. If public charging stations predominantly use the NACS connector, you may want to buy a Tesla for more convenient charging access. Remember, you can always get an adaptor to convert the J1772 to NACS.
Future-proofing your charging solution
If you anticipate owning different EV models over time, the J-1772 connector offers a more near term future-proof solution due to its universal compatibility with various electric vehicles. However, the NACS connector will become the universal charging standard in the coming years. The J-1772 will continue to work just fine for the next several years on most EVs, but eventually, you need to make the switch to NACS.
Conclusion
The choice between J-1772 and NACS connectors ultimately depends on your specific electric vehicle, charging infrastructure, and personal preferences. Whether you prioritize universal compatibility or seek the advantages of high-speed charging within a proprietary ecosystem, understanding the features and benefits of each connector empowers you to make an informed decision on your electric journey.
