I'll second this suggestion. We initially thought we didn't need to bring a spare adaptor because we have a good warranty on our laptops. You should probably be aware of the fact that not many companies are willing to ship parts internationally. That means that you're going to have to use a US shipping address (ICS or Hassell Free) and wait for about 2-3 weeks before you get your part. Be smart and bring a spare.
