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.
