Has anyone used any of the charging station mapping apps that are out there? There seems to be a growing number of apps that are all trying to do the same thing like Chargehub, PlugShare, etc... I'm finally going on a trip where I may need to step outside of the Tesla charging/destination network and I need to do some planning. I'm looking for input from someone's experience on what is the best app that has the most comprehensive list of all the chargers available and could use some help. Anyone have any experience with this?
