answer:Watts = Volts times Amps The overall “power” is measured in watts. If the voltage is the same, but there are fewer watts, then there must be fewer amps. I don’t think that there would be any differences in either volts or amps between cities. It may be possible that the hotel itself has set its electrical outlets to use less power to save money. Another (probably more likely) possibility is that since electrical lines come with different voltages, from massive transmission cables to small power lines, that the hotel’s power line may have less power than the line to your house.
