I just ordered an X and trying to figure out what charger to get. I live in South Burlington, VT. To promote EVs, the local utility (Green Mountain Power) is offering free installation of a FLO Home X5 with a J1772 connector. It operates at up to 30 amps. Do folks think that will work OK with the X, or should I pay Tesla to install a Tesla Wall Connector? Any insight/advice would be appreciated!
