I was at York Motors today (to order a part for my wife's PT Cruiser), located across from a Super Walmart and near the Prescott mall. Surprised to see a J2 charger there, right in front of the main dealership building. Salesman saw me looking, said anyone can use it. Another salesman might say something else, I dunno. But the charger is there, right on the main highway into Prescott coming from the south. Useful in an emergency, etc.
That charger is only available during business hours and is usually iced by their slow moving Pacifica phev. 4.7kW if memory serves. Your best bet in Prescott is Marriott or Audio adrenaline in PV. Prescott is behind the times on so many levels...
