1. Same power as US. Surge protector is good to have.
2. Lagnaippe is great! Especially for those cases of Belikin, water, coke, etc. Would not want to cart the heavy stuff from the grocery. Good fruit, cheese, eggs, etc. Slight charge is worth forgetting the hassle.
3. binoculars, zip-lock bags, a candle, thermal mugs are all nice to have
4. Take half the clothes out of your suitcase! Take twice as much money as you had planned.
