Check your devices carefully as many will work on 110v and 220v. Many won't. Lots of the power strips here have universal jacks so you can plug US cords as well as Uruguayan cords in. A nice convience for your dual voltage stuff and a nice way to zap your 110v volt equipment!I used plastic straps to attached the 110v transformer for my cordless phone to a 110v/220v transformer. The small transformers to convret 220 to 110v are pretty cheap 100 and some pesos... US$5 or so and found at every hardware store.
Bigger ones are a little more difficult to find, but I got one that handles 1000 watts for about US$40.
There are a variety of plug styles used in Uruguay, so whether you bring electronics or buy them here, you WILL need a variety of adapters so you can plug it it.
You'll also find that you'll have cords that have two round pins that just won't plug into a socket that looks like it should take a cord with 2 round pins.
The problem is there are two different size round pins, normal and higher current. A higher current device like a microwave won't plug into a lower current socket as the pins are larger in diameter.
Just read the labels so you don't zap your 110 volt equipment by mistake.
Also leave your TV at home as the USA uses NTSC and Uruguay uses PAL-M so you won't get much of a picture.
