Do I need a Level 2 charger, or is a regular outlet enough?

Q: Do I need a Level 2 charger, or is a regular outlet enough?

A regular 120-volt outlet may be enough. The Department of Energy says Level 1 adds about 5 miles of range per hour, about 40 miles in 8 hours, and that many drivers meet their daily needs charging overnight that way, if there is an outlet on a dedicated circuit near where they park. Level 2 at 240 volts adds about 25 miles an hour, or up to 38 with a 40-amp charger like the Lectron NEXUS, and suits longer commutes, irregular schedules or cars with large batteries.

Home wiring is a job for a licensed electrician. New circuits, outlets, transfer switches and battery connections must meet the National Electrical Code and your local rules, and many need a permit and inspection.

The DOE gives a range of charging times from less than 20 minutes on a DC fast charger to 20 hours or more on Level 1, depending on how empty and how big the battery is, the car's built-in charger and the equipment.

A plug-in Level 2 charger needs a 240-volt outlet such as a NEMA 14-50; Lectron says a licensed electrician must install the outlet and a dedicated 240-volt circuit if you don't have one. The Lectron NEXUS was $419.99 on Lectron's site when we checked on October 25, 2026.
