Can I plug my American electrical stuff in the wall outlets in Mexico? ie cell phone charger, vibrator, etc
Electronics these days don't give a shit whether its 110 or 240v. If its something like a phone charger, laptop adapter, hairdryer, electric razor, etc... you don't have to worry even if you went to Europe, as long as you can physcially get the thing in the wall.
With amps, computers, bigger things like that, it's different, but smaller electronics where the voltage is being converted into DC via a brick or wall wart are never an issue.
Umm, ok, but I've still seen a shitload of busted smaller devices that got over twice the voltage they're made for.
Why did they come up with exactly 127? Is there another country that has the same voltage?
Just keep electronics away from Mexican water, you don't want them getting sick.
