An article is disclosed which provides for powering or charging the battery of a variety of different electronic devices, with the article being in two parts. The first part has components such that it is "universal" for use with all of the variety of different devices, and the second part has components which are specific to the operation of only a single model, type or brand of such device or of closely related devices which operate with the same voltage and plug-compatibility requirements of the specific device.
