I live in the U.K. and I have a Macbook Pro (2016) which I purchased in Dubai. The power adapter works fine in U.K. / Dubai / India.
I am traveling to USA next week.
Do I need to buy the adapter so that it can be used in the 2-pin USA wall sockets or do I also need to buy something in addition to that - say, a step up / step power adapter (My apologies, I am not sure of what it is called exactly... to transform the voltage as well?)
