Newby question (sorry if asking the obvious!) My 2014 Model S came with a blue charging cable and a BMW charger (dont ask!). The BMW charger has a UK 3 pin plug and charges at about 6 miles per hour which is ok I guess. Where can I use the blue cable? I assume it is for use at places where any EV can charge but I am not sure where in the UK they are based and cant seem to find a list or map of them. What cable(s) for charging should come wih a Tesla S? Any advice would be appreciated.
