Oh by the way,
If you want to see what a 3-prong Brazilian wall socket looks like, check it out here:
http://www.kropla.com/brazil_power.htm It looks like a single-type American outlet (5-15) that can also accept Europlug (2 round pin) plugs in addition to the normal 3-pin American grounded plugs.
I think these outlets might also take 2-amp British Standard 546 plugs (really tiny suckers), but not the 5-amp (a bit larger) variety.
Neat configuration -- would be awesome if we could have these in the States for dual-voltage appliances!
