@hacks4pancakes As others in this thread have said that looks like a J1772 socket. Which if your car only supports level 1 and level 2 charging (both AC) makes sense.
When you're looking for public charging you should look for Level 2 charging with a J1772 plug. You shouldn't have to buy anything to use those charges (other than paying for the electricity)
Try using this AAA map https://ev.aaa.com/resources/?value=CHARGERS#chargerscontent
Which you can filter by J1772 connector type.
My guess is you've found a CHAdeMO charger. https://en.wikipedia.org/wiki/CHAdeMO
I haven't used chargemap so I'm not sure how you filter that app.
