Meanwhile, however, the use of the Micro-USB port inside the housing is broken from its moorings, so that it is no longer possible to connect a connector which actually reached the contacts after less than a year. Something may perhaps happen in case of gross violence, in normal operation but not (also charging the phone in your pocket is not a possible cause, because doing so the large USB port on the battery pack is used).
In addition, you get the same price similar products that can be used as a flashlight in addition to charging function yet.
