Last update was delivery to airport in Beijing, Dec 1. I am in Chicago. When can I expect?

I ordered an adapter from site focal price who use chinapost services. I made the order on 23 Nov and the site said it would take 7-20 days to deliver. However, the status still says delivery to airport at Beijing on Dec 1 and I don't know when its going to come. I really need it before Dec 15.
