Just to update, had my charger installed today and can confirm I was able to pick whether I wanted the tethered or untethered Ohme. I went for the untethered Ohme (the ePod) for the reasons I said earlier (I didn’t want the cable hanging around). So massive thumbs up.
I did cheekily ask if they throw in a cable anyway, and they said no. They did say something vague about maybe the dealer will do that when I pick up my car. If they mean the huge 200Kw yellow type cables that come with cars, then that won’t be for me for every day use – too heavy – so I’d plan to leave that in the car for the odd occasion when I want to charge on a long trip.
So will probably end up buying a lighter 11Kw cable of my own for the ePod. Which comes back full circle as the disadvantage of choosing the untethered charger – but that was a risk I was willing to take when I picked it.
Hope this information is of use to someone!
