Are you talking about the unit that goes into the outlet or the actual cord? Far as I knew, the cords were all the same. Its just twisted wire inside a rubber shielding. The unit it plugs into at the outlet is the different part. I use my wife's BB charger and cord and it will recharge from 25% to full in about 2 hours.
I have a charger from Rocketfish that is like that kevm14. I believe I picked it up at Best Buy, but I'm not completely sure. I got it for my Focus last November, so my memory is a little fuzzy as to the specifics.
