Many factors serve to emphasize the uniqueness of a country from its neighboring nations. Perhaps one of the most apparent is the difference in the propagation and utilization of electrical power. Since electricity is a force that is measured based on voltage and frequency, one would think that a device which works in a certain region would do the same when plugged into a power socket across the world. However, this remains yet a challenge as, more often than not, the plug does not fit the socket. This dilemma has stricken many a traveler and caught them unawares. Rather than risking the chance of turning up unshaven for an important meeting, many lug along power adapters in the hopes of matching the correct shape, size and pins to power up their grooming appliances. Electrical power supply within a country or region is also very much like vanilla ice cream. Although the assumption is that there is usually one standard flavor, there may be variations according to geographical locations. One locale may demonstrate tendencies to follow standards of a neighboring country as compared to its national precepts. Other factors driving the varying numbers may be caused by changes in order to comply by the coming together of nations to form regional unions. Fortunately, power adapters are not required as changes normally present themselves as variants in the levels of current, voltage and frequency. In the event these variants are minimal, most appliances should still be able to tolerate and function within a certain upward and downward percentage. In line with increasing statistics of travelers, the universal version of this adapter was designed to alleviate all woes arising out of mismatched plugs to points. This became a relief to many as having to bring the correct version was normally the bane of an inexperienced tourist.
