NACS Home Charger - Features, Benefits, and Installation

The North American Charging Standard (NACS) is Tesla's proprietary electric vehicle charging connector. Even before the move to standardize it as SAE J3400 was started by SAE International, EV enthusiasts have already dubbed it the "standard" of charging mainly due to its robust network, sleek design, simple operation, and a user-friendly plug in hybrid Tesla app. While the J1772 has long been the charging standard for non-Tesla EVs in North America, the lack of cooperation among charging solutions providers ultimately became a drawback.

With multiple car companies taking responsibility for their own infrastructures, some public J1772 charging stations may not receive the same level of maintenance as others, resulting in the unavailability of chargers in some locations. This may or may not affect the uneven EV-to-charging station ratio, especially in areas where EVs are not as common, hence, the lack of reliable charging infrastructure and the corresponding maintenance. Previous studies show that some locations report J1772 and CCS (Combined Charging Standard) connectors to be only available 72% of the time, while Tesla chargers have a 99% uptime.

Non-Tesla drivers have long been craving this level of interoperability and software integrity. And they're about to get what they wish for when the NACS officially becomes the connector of choice for North American EVs. Major carmakers Ford, GM, Rivian, and more have already pledged allegiance to NACS, announcing the release of their NACS-equipped electric vehicles as early as next year.

Benefits of NACS Home Charger

For 80% of EV drivers, EV charging is still done at home. Not only is it time-efficient as you can leave your car charging overnight, but it also saves you money in the long run with utility service providers offering time-of-use rates on energy consumption during off-peak hours to charge your vehicle.

Home charging also increases the accessibility and purchase of EVs for more people. Installing a home EV charging station for those living in single-family homes with garages or dedicated parking spaces is a straightforward solution. This increased accessibility helps in promoting the adoption and purchase of electric vehicles.

The Best Tesla Home Charger You Can Buy

Finding a native Tesla NACS adapter or home charger may be tricky. However, Tesla's open-source policy allowed third-party manufacturers to produce Tesla connectors, helping the carmaker to cater to those who want options besides the Tesla Mobile Connector or the Universal Wall Connector.

The impending standardization of NACS is expected to bring the long-awaited unity in the electric vehicle industry. The transition from individual infrastructures to a standardized plug approach promises enhanced accessibility and efficiency, addressing concerns such as uneven charging station maintenance and availability. Once all major automakers jump ship to this plug type, it will help eliminate the doubts of EV skeptics and promote a wider EV adoption.

With third-party manufacturers producing native Tesla NACS home chargers, EV owners have more options aside from Wall Connectors and Mobile Connectors. This diversification not only offers consumers more choices but also promotes competition and innovation within the home EV charging station and market.


  • Is a NACS charger better than a J1772 charger?

    While both J1772 and NACS chargers serve the purpose of electric vehicle charging, the NACS system has the advantage of a more robust network and higher uptime compared to J1772 chargers. Additionally, NACS chargers offer seamless compatibility with Tesla models and other EVs using the standard, promoting interoperability and ease of use.

  • Who makes NACS chargers?

    NACS chargers are manufactured by Tesla and licensed third-party adapter manufacturers meeting proprietary connector specifications.

  • Which manufacturers are switching to NACS?
