Only the red rubber around the metal connector needs to fit tight

Original review great charging speed but the build is pretty bad

The mini usb output on the red wire that connects to my phone doesnt easily fit into the port on the charger and after trying to maneuver it in over a few times it got stuck and got pulled out of the red wire

Now it falls out of my phone and doesnt charge it

This little charger is perfect except in one small way in that it doesnt pass through i have an import car that doesnt charge your phone except when its running and then when its running this doesnt charge your phone

Consfirst of ill start with why i knocked off a star one is because the micro usb port on both ends is very specific to the cable that comes with the power bank itself so you cant really use any micro usb cable with this power bankbecause it wont fit in the port
