What is this pin called? Lost my LED lamp’s charging cable - eviltoast

I know it’s the old round pin we used for phones back in the day but can someone send me a link to the exact one because I’m seeing too many round pin charges of different sizes. Also where do I go for tech help related questions like these? Is this the right community?

    Ah yes, you must mean the biblically accurate universal barrel plug adapter.

    Edit: I had something like this guy growing up and used to use it to make sparks and other shenanigans.

      What utter goofball was it who ever built a device with reversed polarity?
