Everyone's situation can be different. I've been using my mobile charger for home charging, only installing a 30A plug into an existing circuit. Never yet unplugged the mobile connector after first plugging it in 5 years ago. If I get another Tesla, I'll continue that same approach I imagine. Traveling, I always have Tesla Superchargers or Tesla level 2 destination charging available. Never yet used the first adapter or searched for a charge. 20-22 mph charging is plenty for home charging.
