Lectron J1772 vs NACS Portable EV Chargers
Charging Level Flexibility
Edge: Lectron NACS Portable EV Charger 40A
The Lectron Nexus 40A is a dedicated Level 2 station. It plugs into a 240V NEMA 14-50 outlet and delivers consistent high-speed charging. This model does not support Level 1 charging. In contrast, the Lectron NACS Portable unit offers dual-level capability. It includes both a NEMA 5-15 plug for standard 120V outlets and a NEMA 14-50 plug for 240V power. This allows you to charge at 8 amps anywhere you have a standard wall outlet, or switch to 40 amps for faster home charging. The portable unit provides more versatility for different power sources. Product A offers fixed Level 2 performance only, while Product B supports both Level 1 and Level 2 modes.
Connector Compatibility
Edge: Tie
Connector type is the primary differentiator between these two Lectron chargers. The Nexus 40A features a standard J1772 connector. It works seamlessly with all electric vehicles that use the J1772 port. Tesla vehicles are supported only if you use a compatible NACS adapter. The portable unit uses a NACS connector. It is fully compatible with Tesla models including the Model 3, Y, S, X, Cybertruck, and all other vehicles in the North American Charging Standard alliance. If you drive a non-Tesla EV with a J1772 port, you need the Nexus. If you own a Tesla or a NACS-compatible vehicle, the portable unit connects directly without adapters.
Cable Length and Reach
Edge: Lectron Nexus 40A Level 2 EV Charger
Cable length affects how easily you can position the charger. The Lectron Nexus 40A comes with a 23-foot cable. This extra length provides more flexibility for reaching the charging port, especially if your vehicle is parked slightly away from the wall mount. The Lectron NACS Portable unit has a 20-foot cable. While still sufficient for most garages, it is three feet shorter than the Nexus. The longer cable on the Nexus reduces strain on the connection and offers a bit more room for maneuvering. Both units include mounting options, but the Nexus provides greater reach for difficult parking spots.
Monitoring and Feedback
Edge: Lectron NACS Portable EV Charger 40A
How you track charging progress differs between the two models. The Lectron NACS Portable unit features real-time monitoring capabilities. It includes LED status indicators on the device that allow you to track charging progress and monitor any faults directly from the charger. You do not need an app to see the status. The Lectron Nexus 40A specifications do not mention real-time monitoring features or LED status indicators for tracking progress. It focuses on safety certifications and physical durability. If you want to see immediate feedback on the charging state without using a smartphone, the portable unit provides this visual information directly on the hardware.
Power Output and Speed
Edge: Tie
Both chargers deliver up to 40 amps of power for fast charging. The Nexus 40A operates at 240V and provides a power output of 9.6 kW. It adds up to 38 miles of range per hour. The portable unit also supports up to 40 amps when plugged into a NEMA 14-50 outlet. However, its maximum power output is not explicitly listed in the specifications, though it matches the amperage of the Nexus. Both units are designed for rapid charging when connected to 240V power. The speed difference is negligible at the maximum 40-amp setting. Both provide high-speed Level 2 charging for compatible vehicles.
