short angled cables. I'll find a micro USB-regular USB cable to connect the two.
That was said on the assumption that the user of the phone had intention of leaving on the display, cycle apps and gps on even after the internal battery was fully charged from the external source. The display alone will draw a fair amount of current if the phone was left on for the GPS tracking and app. In this case, there should be fair amount of current draw such that the external battery will remain on. However if one were to shut off the phone and set it on standbye after the battery is fully charged up, then the external battery may automactically power off.
That connector you linked is not too bad of an connector. The Micro B end fit into my Samsung Note 2 fairly well. I had some other cheapy cable where the micro usb will fit either too tight or wiggle around too much. So far, I have three of the Star Tech micro and mini USB and they all seem to be consistent and hopefully stay that way in the future (knock on wood).
