One of those chargers likely costs $200 to $300 to build and from $300 to $2000 to install (YMMV). They could give them away free to the right locations and let the local business take care of collecting from the customer. I imagine that, depending upon the business, either a flat fee of $5 to $10 or no fee would apply. I actually thought about purchasing an extra charger (as shown in the options) and giving it to a B&B where I stay regularly.
