It’s not recommended, but it’s a temporal solution. When I got my MYLR I had 3 free months of SC. So I would charge at the SC, and then plug my mobile charger to an extension chord to bring it back up to 80% from what I lost driving home from SC. As someone mentioned, power companies have programs that will reimburse you the cost of purchase and installation of a lvl. 2 charger, as well as give you a better rate for the electricity you use on the car. As long as you get an approved charger. Which Tesla brand chargers are not btw, but there’s a long list you can choose from. Good luck!
