Power adapter to connect Thinkpad X230's power adapter into an X240

http://www.ebay.com/itm/Power-converter-Cable-Adapter-For-Lenovo-ThinkPad-X1-Carbon-0B47046-Nice-Joli-/381151966274?

I got the above item but it is not what I'm looking for : it's for Energizer XP18000 or some other external power banks
to connect to a Thinkpad X240.

I have a few pcs of X230 power adapters on hand but would like to be able to plug one of the
X230's power adapter into X240.

Currently my spouse has an X240 & it's heavy to carry the adapter around, so she thought of
leaving one at office & at home, could use my spares X230 adapters.

Can anyone provide me any eBay link for such an adapter?

I can always buy an extra piece of the above X240 adapter to resolve my issue but
I'm looking for a small adapter that costs US$5 or less & I have too many X230's
adapters lying around & don't want to choke my house with more

This Lenovo support page suggests a 65-Watt adapter can be used with the X240 which is the same size adapter as for my X230. Only the tip is different.

So either use the adapter specified for the X240 (should be the same weight as the X230), or be sure you have a correct adapter part. I prefer the proper adapter.

Which of the item (let's fix the top-most item as item #1) in the Lenovo page is the adapter you're
referring to?   Any equivalent item in eBay?   Do provide the eBay link

Pick the 65 watt adapter. 4th one down when I look at the list. It has the slim tip for X240.
