Questions about this item

What power supply do I need that has a 5.5 2.1mm plug for this adapter?

You need a power supply or charger that terminates in a 5.5 mm outer diameter and 2.1 mm inner diameter barrel plug to connect to the female end.

Will this let me use my older ThinkPad X230S square-tip charger with a standard barrel jack device?

No, this adapter converts a 5.5 mm by 2.1 mm barrel plug into the square tip required by the ThinkPad X230S, S3, S5, X1 and E431 models.
