Samsung ARM Chromebook power connector?

I have a Samsung XE303C12-A01US sitting around, and I was trying to determine what kind of power connector it uses.  The outer diameter measures 2.48mm.  I can't measure the pin directly, but I'm able to fit a 0.63mm wire into the hole fairly snugly.

I tried ordering one of the "2.5mm x 0.7mm" connectors available on eBay, and it's not quite right.  The outer diameter is perfect, but it holds the pin too loosely to maintain a solid connection.

So what you really need is a "2.5mm x (something less than 0.7mm)" connector, but I can't find anything like that for sale, or on Wikipedia.  Maybe it's a custom part?
