Although i forgot to show it in the video the battery case also included a plug that fits into the headphone jack since most normal headphone jacks would not fit since the hole becomes recessed into the case

However there are times when i using the phone with the gps or some other battery hog and wanted to have a portable way to extend out my battery life without carrying a separate charger

This battery case by stalion is an excellent choice

It adds around 14 of an inch to the top of the case and a little bit of thickness to it
