I have plans B and C for the chargers I'm heading for, but my main concern was either that they would be too busy (particularly Killington Lake) or out of order. But I'm travelling midweek and in the middle of the day, so hopefully...
Killington Lake is Gridserve, and plan B is an Instavolt.
I've been quite sceptical about anyone actually running out of charge nowadays, given that most cars have a decent range, there are chargers all over the place, and EVs can crawl quite a long way in turtle mode. But I don't want to be stuck on some 7 Kw type 2 when I've still got 100 miles to go, or find myself scouting for friendly folk with wall boxes (or even a 13A socket!) because my car won't connect to anything!
