The structure is similar to the low-charging stations. This means that the material is plastic, the shell a little too easily. But nevertheless an essential part is better: A cumbersome for the charging current hurdle is missing: the ability to use large USB plug back. This can be surprising as the Billigheimern. There you have the choice between USB and micro USB. For but a small board with a circuit is then needed inside. And the costs significantly charging current. What first looks like an advantage, thus turns out to be veritable current brake. The original Sony charging station, however, the smartphone will be as soon as charged on the micro USB socket on the smartphone itself. A star deduction there, because the price is too exaggerated. Although the omission of part clearly has advantages here, so still the material and equipment expenditure is actually lower.
