There are eight Tesla superchargers at Woodman's grocery in North Aurora IL. If there is a J1772 there, would it be an extra hose on one of the chargers? I haven't really examined them closely because I was so steamed to see so many Tesla chargers and nothing for me. Have only seen one Tesla charging there, one time. Most of the time all are empty. No one at the store knows anything about this, so there's no one to ask.
Most do, I believe, but not all. Tesla happily pays for one J1772 for every two HPWCs they install if the owners of the site want it.
