Hi, I have two types of european adaptors; both with 2 round prongs but one adaptor's prongs are thicker than the other's; one of these is labeled 'Northern Europe'. The other one probably doesn't apply to CR because it's label only mentions Southern Europe. But would CR be considered Northern Europe? We refer to it in the USA as 'Eastern Europe' but I haven't come across an adaptor labeled for Eastern Europe. Thank you.
