The Lectron 40A J1772 is a popular, affordable portable charger with a genuinely useful onboard LCD and, in the Wi-Fi version, app scheduling. TorqueNews called it a "fantastic value," EVchargerReviews.net scored it 3.5/5 and EV Adept buyers rate it 4.5/5. The catches are a short cord and a documented tendency to throttle below 40A when it runs warm.
