- Lectron launched the NEXUS, its second-gen Level 2 home EV charger, available now as a non-wifi model in NEMA 14-50 plug or hardwired versions, with a connected version due in the next few months.
- Lectron now supplies more than 15 global OEMs including Ford, GM, and Mercedes-Benz, and each charging adapter contains around 60 components that must pass OEM engineering vetting before any automaker logo is applied.
- CEO Chris Maiwald outlined a three-stage quality process: design-phase risk identification, process failure mode analysis, and end-of-line testing covering electrical performance, IP rating verification, and aging chamber testing.
- The NEXUS assembly line assigns a unique serial number to every charger and digitally logs each build step — right down to the quarter-turn of a screwdriver — with cameras capturing internal layout images at multiple stages for traceability.
- The NEXUS carries an IP66 weather-resistance rating plus UL 2231, UL 2251, UL 2594, and UL 817 certifications, and the NEMA 14-50 version adds a temperature sensor on each hot pin as a safety measure.
- Wirecutter named Lectron's portable Level 1 & 2 EV charger "the best J1772 charger to carry with you" in April.
Why it matters: With 40 to 48 amps flowing through a compact home charger for hours — often mounted outdoors — Lectron's serialized, image-logged assembly and three-stage QC are the safety floor that earns spots on OEM supplier lists. Moving from Home Depot shelves to contracts with Ford, GM, and Mercedes-Benz quietly positions Lectron as the adapter-and-charger middleman in the NACS transition.
