I could be wrong (often am, some would assert) BUT I suggest we all agree on the nomenclature of this thread:
- What do you/everyone else mean by "adapter"? IME there are power adapters and plug adapters.
- Are you using that term to refer to a small device into which your 'Book's 110 US plug fits, so to adapt to the shape/size of a UK or "EU variant" of a wall socket?
- Or, are you using it as a synonym for a power transformer, aka a power "brick", sometimes confusingly called an "adapter"?
- Why are we worrying about 3-prong grounding? Modern 2-prong plugs are designed with polarized plugs for adequate safety (one prong larger than the other, always carrying a tag with a legend saying to be sure one doesn't try to insert it the "wrong" way!)
- I'm sure you are not referring to an "invertor", such as would be used to charge/operate your 'Book from a socket in your automobile . . . some might think of one (incorrectly) as an "adapter".
- Or . . .?
I have a strong impression (memory) the the Apple "brick" has for some years been seamlessly "adaptable" to 110v to 220v w/o embellishment or modificaition, except for the plug end which does require an adpater for various parts of the world.
Note to Paddy: Ask that double-E of yours which he predicts will come first: George and Highmac and Peter and the Japanese driving on the "right" side of the road, or a universal electrical "plug"
While LewisNClark (in my personal experience) is a highly dependable producer of excellent travel goods, I doubt that you need anything quite so imposing as they offer on your link..
Kensington has a set of different "bricks" (more like small pieces of toast, in size), but more importantly they have a really clever "nest" of plugs for adapting any OEM/USA plug to most anywhere in the world that discovered fire > 62 years ago.
Kensington might be your solution
