Highbury DC charger competitors, page-12

Hi 3500. Hope you can clarify because I'm no technology expert. Ignoring bi-directional capability for a minute (which seems a great feature), are you saying that the Highbury Wall charger produces DC and cars with or without onboard chargers can accept this to charge their battery? Is Praetorian perhaps saying the opposite - ie that if the car has an onboard charger then DC charging from the Highbury won't work (only AC) or is he implying that its just the extra cost of the Highbury won't be accepted if cars already have onboard chargers and can be plugged into a AC power point? Sorry - I'm obviously a novice with the technical side.
