Depends. Says a full charge can be achieved in under 2 hours but that would be reliant on getting the advertised max rate of charge (which you often don't get).
Finding a charger for a coach is probably more problematic than finding one for a car I would wager.
Doug why don’t you buy 1/2 dozen coaches and do ticket/travel deal ? You will get the cost of the coaches back easily. Then on home matches use them to pick up fans from around the City . Because the location and transport has to be the worst in any City .
