The electrical current for electronics in Mexico is exactly the same to what we have in Canada and the US. All my laptops move back and forth from Canada to the US, and when we bought some electronics from Canada, the experience was exactly the same.
On some of our electronics, we use surge suppressors. If you own a home in Mexico, it would be a good idea to have surge suppressors. In our condo, everything has been pre-arranged for us in the building. That means we have our own generator, so our electricity is stable. Outside of our complex, you would need something to protect your electronics from electrical spikes.
