Lectron Nexus NACS vs J1772 Specs

Connector Compatibility

Edge: Lectron Nexus 40A NACS EV Charger

The primary difference lies in the connector type and vehicle compatibility. Product A, the Lectron Nexus 40A NACS EV Charger, features a SAE J3400 NACS connector. This allows it to work seamlessly with Tesla Model S, 3, X, Y, and Cybertruck, as well as next-generation EVs like the Hyundai Ioniq 5 (2025) and Kia EV6 (2025). Product B, the Lectron Nexus 40A Level 2 EV Charger, uses a standard J1772 connector. It works with all J1772-equipped electric vehicles. Tesla owners can use Product B, but they must use a separate NACS adapter. If you drive a modern Tesla or a new NACS-native EV, Product A is the direct fit. For other EVs, Product B is the native choice, though it requires an adapter for Tesla.

Charging Power Output

Edge: Tie

Both chargers deliver identical charging performance in terms of power output. Each unit operates at 240 volts and 40 amps, resulting in a maximum power output of 9.6 kW. This level 2 charging capability allows you to add up to 38 miles of range per hour to your electric vehicle. Whether you choose the NACS model or the J1772 model, the speed at which your battery fills up remains the same. The internal electronics and power delivery systems are matched, ensuring that neither product offers a faster charge rate than the other based on electrical specifications alone.

Power Input Requirement

Edge: Tie

Both units share the same power input requirements, making installation straightforward for most homeowners. Each charger is designed to plug into a standard 240V NEMA 14-50 outlet. This means you do not need to hire an electrician for hardwiring if you already have this common outlet type available in your garage or driveway. The amperage draw is capped at 40 amps for both models when using this plug configuration. This shared compatibility ensures that the electrical infrastructure needed to support one charger will fully support the other, removing any potential hurdles related to your home’s power supply.

Cable Length and Portability

Edge: Tie

The physical design regarding cable management is identical for both products. Each charger comes equipped with a 23-foot cable, providing ample reach to connect to vehicles parked at varying distances from your mounting location. This extra-long cable length is useful for larger SUVs or trucks that may not align perfectly with the wall mount. Both models also include a charger holster to keep the cable organized and off the ground when not in use. The length and included accessories are the same, so you will not gain or lose convenience in handling the cable by choosing one over the other.

Weatherproof Rating

Edge: Tie

Both chargers are built to withstand outdoor conditions with the same durability standards. Each unit holds an IP66 weatherproof rating, which means they are protected against heavy rain, snow, dust, and high-pressure water jets. This certification allows you to install either charger outdoors without concern for weather damage. The internal components are sealed to prevent moisture ingress, ensuring reliable operation in rain or snow. Since both the NACS and J1772 models share this IP66 rating, you can place either device in the same outdoor environment with equal confidence in its weather resistance.

Safety Certifications

Edge: Tie

Safety and regulatory compliance are matched between the two models. Both chargers are UL 2594 certified and ETL listed, indicating they meet automotive-grade charging safety standards. They also carry UL 2231, UL 2251, and UL 817 certifications. These cover shock protection, cable integrity, and system reliability. Each unit includes built-in protections against overheating, overcurrent, voltage faults, and ground faults. Additionally, both are Energy Star and FCC certified. You receive the same level of safety assurance and regulatory compliance regardless of which connector type you select, ensuring both devices meet strict independent testing requirements.

Warranty Coverage

Edge: Tie

The manufacturer’s support terms are identical for both products. Lectron provides a 3-year limited warranty on the Nexus 40A NACS EV Charger and the Nexus 40A Level 2 EV Charger. This coverage begins from the date of purchase and applies to both models equally. You do not receive extended or reduced warranty terms based on the connector type. This consistent warranty policy means your long-term protection against manufacturing defects is the same for either choice, giving you equal peace of mind regarding the durability and support of the device you purchase.

Frequently asked questions

Can I use the Lectron Nexus 40A NACS charger with a non-Tesla EV?

No, this charger features a native NACS connector designed specifically for Tesla vehicles. It does not include a J1772 adapter in the box. You would need a separate adapter to charge other electric vehicles. If you own a non-Tesla EV, the J1772 model is the correct choice for direct compatibility.

Does the Lectron Nexus 40A J1772 charger work with Tesla vehicles?

Yes, but you must use an adapter. The J1772 connector does not plug directly into Tesla ports. You need a Tesla J1772-to-NACS adapter to charge your vehicle. This adds an extra step compared to the native NACS model. It remains a reliable option if you primarily drive a non-Tesla EV.

What is the maximum amperage for these Lectron Level 2 chargers?

Both the NACS and J1772 models support up to 40 amps. This high amperage allows for faster charging speeds compared to standard 16-amp or 32-amp units. You get consistent power delivery at 240 volts. Ensure your home electrical circuit can handle a 40-amp load to achieve these maximum speeds safely.

Do these chargers require a special electrical outlet?

Yes, both models use a NEMA 14-50 plug. You need a compatible 240-volt outlet installed in your garage or driveway. This is the same outlet type used for electric dryers. If you have a NEMA 6-50 outlet, you may need a compatible adapter, though native 14-50 is the standard for these units.

Is there a difference in charging speed between the NACS and J1772 versions?

No, the charging speed is identical for both models. Both deliver 40 amps at 240 volts. The only difference is the connector shape and vehicle compatibility. Your car will charge at the same rate regardless of which Lectron Nexus unit you choose. The choice depends solely on your vehicle's port type.

Which Lectron charger is better for a mixed household with Tesla and other EVs?

The J1772 model is more versatile for mixed households. It works directly with most electric vehicles on the market. Tesla owners can use a simple adapter to charge. The NACS model only works with Tesla vehicles without additional hardware. For flexibility, the J1772 version accommodates more drivers and car types.
