There does not seem to be a single source for charger locations, or plug in places,or is there? No need for chargepoint.com as a suggestion, only their chargers, the built-in entune charger finder is limited as well.
That's why I asked, you try it, type in 20878 or Maryland on the first site "no free charging stations in Maryland", while I know of 3 in my area.
iPhone apps as well. Sorry, but I don't think there is just one that shows everything. Also, it tool like four months for a new one (1 mile from my house) to finally show up. Keep your eyes open...
Unfortunately, no. See My Nissan Leaf Forum • View topic - Public charge station lists and the replies for other databases.
One problem with the apps that show all charging stations is that often some of the charging stations shown at nonexistent. Plugshare, Recargo The chargepoint app is most accurate in their specific station listing. On plugshare and Recargo I will make a note on check-in if the station is no longer existent.
