AFAIK, the outlets in and are the same but not like those in the UK. I've used this type in France and, but I've never been to Spain.Just FYI, you don't list anything with a 3 prong plug that you're bringing, but I realized in the Chicago airport that all my adaptors could only be used with 2 prong plugs, so if you're taking a 3 prong one, make sure you get one that will work. I got mine from Brookstone in the airport and it's worked in the UK, France, and Germany (you change it around for different outlet types).
It even worked to charge my cell phone I bought in the UK when I got home to the US.I haven't had much luck with using the USB ports though for some reason. Things don't seem to charge well with them, so I just plug them in (ipod, kindle). A multi country adapter as in btgm's second link may be the business: basic models are just that: basic. There are adapters that come with surge protectors; worth the extra spend. There may never be a power surge when you charge your goods, but unfortunate events do happen.If you buy at a local shop then slide the shutters up and down to ensure they don't stick in one position, otherwise you'll end up with a multi country adapter that may be good for one part of the world only.

If he thinks it's an issue he should equip his house first which is no doubt where these things are charged 99% of the time.
