They come with the adapter for standard level 2 chargers, and adapters can be purchased for any 220v outlet as well.

Most major towns have chargers, I was visiting family in the Northeast Kingdom last year and had no problems charging in St J, Newport, and Littleton. With a 300 mile range, the real issue was that I couldn’t charge overnight at my family’s place, so I had to plan a trip out two to town in order to charge. Not that the local businesses complained.
