correct, want to plug the polestar into the 15amp plug.As in plug the Polestar into the 15A power supplies that caravan parks provide?
Unless I am mistaken (not familiar with caravan park 15A sockets), the 10A granny charger should fit into a 15A socket. The only difference between them is the size of the earth/ground pin, which is bigger on a 15A circuit to prevent you plugging the 15A cable into a 10A socket. But the other way around (10A into a 15A) fits fine.
That being said, whilst it fits, no idea if caravan parks allow it ??
I’ve messaged them to tell them what I want to do and they haven’t objected.
thanks for your response, really helpful
