There are too many unknown variables to make predictions like this. I predict that Lowenthal has the best take - businesses will invest in chargers outside their businesses because it will bring customers. They will be able to charge less than stand-alone chargers because of increases in business revenue. Which will lower the prices on stand-alone chargers as well, because prices are set where marginal revenue equals marginal cost, and companies are price setters only if they have market, or monopoly, power. The competition will keep prices low.
