Another shore power question

[Mountainman]

We rented a few slips at Bullfrog for our upcoming fishing trip. It’s been a very long time since we’ve rented a slip and never had the need for shore power until now. The person we spoke with at the marina told us we can plug our boats in to charge batteries. I ask if we just need a standard extension cord and was told “I think so?”. I had them send me a picture of the receptacle. Can someone explain what this style of receptacle is and if it’s possible to use for charging batteries? All of our onboard chargers are AC 120v.

You’ll need this adapter to convert 30A shore post (in your picture) to standard 110V for your charger
