Please help me find a Lenovo thinkpad 13 ultrabook ac adapter

I messed up the charger end that plugs up to the computer. The yellow plastic part that outlines the plug came out. I can still plug it in to charge, but now if I don't plug it in correctly it say that this is the incorrect charger and it won't charge. So I thought I will just get another charger just as back up.
But I don't know why it is so incredibly hard to find a charger for the lenovo thinkpad 13 ultrabook!! I looked on the lenovo website and can't find the exact model as the one I have. ADLX45NCC2A.

When I asked one of the Lenovo reps through chat the first guy recommend me one model that cost $70 which is just too expensive I feel. I have looked on amazon and I see every other charger than a charger for the lenovo thinkpad 13. I ended up ordering this adapter. I asked in the question forum and some people said that it should work and the seller did as well -_-, but I am a little supicious. It doesn't have any bad reviews except for 1 but it only a couple of reviews. What if they are fake TT_TT I really don't want to destroy my laptop by using a charger that is for it. It finally came today and I am too scared to use it.

I'm at a lost. I might just keep using this charger since it more or less still works it just missing the yellow plastic part.... TT_TT

Hi, thank you so much I will give these a try (TT^TT). The ebay one looks exactly like mine. The extension cord is two prongs instead of three prongs like the others.

But one more question. Would you recommend that I return the ac adapter I bought here
