The car went from 79% state of charge down to 77%. I did use the app to check on it once or twice a day. That is pretty good and wouldn’t worry me for leaving it in airport long term parking for a similar duration.I have charged it twice now using a 120V, 15A outlet and I seem to get enough charge for my usage though this being Covid my usage is down.It does look like I’ll take my first trip where I’ll have to use a supercharger at the end of this month or beginning of next month. I assume I just need to have a valid credit card on file with my account but I’ll do some research before heading out.</blockquote>
