They told me the charge time at 110 was 50% faster than the original. IT WAS TRUE. It is always fully charged in the morning. By the way I am averaging on electric over about 35MPG. The 45E is the best vehicle I have ever owned.

WARNING: its VERY IMPORTANT to point out to newcomers that with such a third-party device, its level 1 charging with 110/120V is fixed at 16A, so while you
can use a common household outlet to charge from 0-100% in ~11h,
it must be a dedicated 20A circuit. the issue is most are only 15A, so the max charge rate is only 12A which takes ~17h to charge. your setup doesn't simply work for everyone; there are safety concerns attached. if they're not addressed, a major thermal event can occur
