I have used a couple different ones in the x2 that both worked. The one that was packed with the openbox x5 worked. My old one that I bought years ago also worked. I would get one from ebay or amazon. Probably around 10$
there is many prices for this adapter on e-bay and amazon, all depends how soon you want it and where they come from.
pricing range 6 to 10 dollars, I paid around 7.50 dollars.
Hope it works.
