When you visit family, are you just there for 30 minutes and then gone? L1 charging is often overlooked, but if you turn off all of your phantom battery draining features, over the course of a day you can really add some miles via L1. Use a quality extension cord if you must.
Yeah, in non-freezing temperatures, I get about 1.5% per hour with a regular outlet. A 5-20 pushes that up to 2%. If you are staying for more than a day, this can really be significant.
For us it is about getting to the relative. Plugged in at my sisters house and really didnt use the car much at all during the week because it needed to charge enough for the start of our round trip. Back then no Sikeston, Memphis or Little Rock charger. We stayed over night in Sikeston and parked car at an RV park and paid $5 to charge overnight. Had lunch in Memphis and had Blink charger charge just enough in 2 hours for us to barely make it to Little Rock. Then charged all week. On way back we tried to skip Memphis and ended up having to stop at another RV park and charge for an hour in the cold with the heat minimal to make it to Sikeston and charge overnight. Next few times we had Sikeston and Memphis SC so not as much adventure, but the Memphis charger really is out of the way.
Memphis is nice with all the restaurant options but holy crap is it out of the way! I can't imagine what tiny amount of Tesla population it's actually convenient for. I suspect when Brinkley and Blytheville come online the Memphis location loses more than half its highway customers. It's only 155 miles between Brinkley, AR, and Jackson, TN; which is very doable in a quick charge on any Tesla. The trip between Brinkley and Blytheville, AR, is shorter than that. Hopefully Brinkley comes online in March for my upcoming road trips. Good riddance to Memphis SuC.
