Get a "whole house" regulator/surge protector
I agree Jesse but when I looked into AVR's and choose one to cover just one outlet, it weighs about Five lbs.
(I bought 3 of them)
I wonder what an AVR to cover the whole house would weigh / cost. (I have to carry it in my suitcase).
As far as the Surge protectors go, I brought one down last trip and have some more to bring down next trip.
They will protect to 4320 Joules and also handle cable for TV and Internet.
