I stupidly failed to pack any of my adapter plugs for the various devices (MacBook Air, iPhone, two iPods, Kindle, digital camera, a portable DVD player, and portable speakers for the iPod) I brought with me. (Okay, okay, I admit I have a hard time cutting the technological cord when I travel!) I have a couple of cheap European adapter plugs as well as the Apple World Travel Adapter kit back home, but that does me little good now! So I am rationing the use of each electronic gadget for the time being, as there apparently is not an appropriate adapter for U.S. plugs to be found in the south of Portugal--and I have looked in the resort newsagent, two local supermarkets, an electronics store, and a Staples office supply store. I did find an adapter for U.K. plugs in one store, which didn't surprise me as the majority of guests in this resort seem to be Brits (apparently this is a favorite holiday and retirement destination for the English).
I did, however, discover online an entertaining article on why plugs and voltage are different around the globe. It's an educational and witty read.
