Lectron Nexus 48A vs Emporia 48A
Short answer
Both are 48 amp units delivering 11.5 kW on a 60 amp circuit, and both carry a recognised safety listing. The differences are practical rather than electrical: cable length, how good the app is, how the enclosure mounts and what the warranty says. Emporia is the cheaper of the two and has the more developed energy monitoring; Lectron has a strong accessory ecosystem around adapters.

Choose the Lectron Nexus 48 A J1772 EV charger if…
Choose the Lectron if you also need adapters, since buying the wall unit and the adapters from one brand means the compatibility question is answered by the manufacturer rather than by you. That matters in a household moving between NACS and J1772 vehicles, where adapter quality and current rating are safety relevant rather than a convenience choice.

Choose the Emporia Level 2 EV Charger, 48 A, J1772 if…
Choose the Emporia if you care about seeing your charging consumption in detail, particularly if you are on a time of use tariff and want to prove to yourself that the schedule is working. The two are close enough on price and function that either is a reasonable purchase, and neither choice changes the installation, which is the expensive and safety critical half of the job.

Common questions
Does cable length matter more than amperage?
Often, yes, and it is the specification people regret. A cable that will not reach the charge port on the side the car happens to be parked means reversing in every night or moving the charger. Measure the actual route from the intended mounting point to the port before choosing, and remember that cable does not stretch around a corner.
What does ETL listed mean?
It means the product has been tested and certified by Intertek to the relevant safety standard, and it is equivalent in standing to a UL listing for code purposes. Inspectors look for a listing from a recognised testing laboratory. Equipment with no listing at all is the thing to avoid, whatever the price.
Do I need Wi-Fi for the charger to work?
No. Every unit here charges without a network connection; connectivity adds scheduling, monitoring and firmware updates. If the charger is in a detached garage with a weak signal, plan for that before buying a connected unit, since a charger that cannot reach the network is simply a charger without those features.
Who sets the amperage on the charger?
Your electrician, at commissioning, based on the circuit that was actually installed. Every unit here has a setting that must match the breaker and conductors, and setting it higher than the circuit supports is dangerous. This is one of the reasons the installation is inspected rather than left to the owner.
