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

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?

You can order an adjustable power supply with a bunch of swappable tips on Amazon.
Also be careful with polarity. Here is an article with some basics of power jacks.
