Built with an aluminum alloy body for extra durability, this 40-amp Level 2 charger plugs into a NEMA 14-50 outlet and delivers up to 9.6 kW, with app-adjustable current settings of 40, 32, 24, or 16 amps to match your home's circuit or ease into overnight charging on a 1-to-12-hour schedule. The LCD display shows real-time charging status so you always know where things stand. A 25-foot cable, about 28 feet including the control box, reaches across most driveways and garages, and the 100% copper wire core with a thick TPE flame-retardant jacket keeps resistance low and heat generation minimal during long sessions. The control box carries a NEMA Type 4 waterproof and dustproof rating, working reliably from -20°C to 50°C through rain, snow, or summer heat. Eight layers of protection guard against lightning, leakage, grounding, over- and under-voltage, overcharge, overcurrent, and overheating, so the 16.1-pound charger stays safe to leave plugged in overnight.
