High Voltage in Mexico


We are spending winter in Mexico, and, as warned, many (most?) of the Rv parks have 15 amp, or 15 amp with 30 amp fitting, and most of the voltages run in the 128 to 130 range, unless a heater/hot plate or such is running.

At what point should I be concerned that 128-130 voltage is a problem? I might add that I have a Surge Guard surge protector which is mounted at the mast, and we do not have a television. We also have a surge guard strip for the plug which charges the laptop. So the major concern, for me, is the refrigerator and the converter.

Any comments/advice would be greatly appreciated. By the way, the Surge Guard blocks the power when the voltage exceeds 132 for 8 seconds.

Thanks, and All the Best... Jeff Cooney

I can't think of any ill effects of higher than normal voltage. Your converter will make the correct voltage for your 12 volt stuff. I am betting that your laptop supply is a multi-range device that will operate between 120 & 22o volts and between 50 to 60 hertz. These modern solid state power supplies are much more capable of dealing with ranges like that than just a transformer would be.
I am guessing that you will be just fine...
