Today a buddy at work got a new PowerBag, come to find out the micro usb cable would not charge his Galaxy Nexus. The .8 A that the micro USB port was putting out was not enough to charge the device.  Luckily there was an apple port that was rated to charge devices at 1 amp. Since he doesn’t own any apple devices,  a quick snip took care of the Apple plug. A little solder, and a donor micro USB cable the PowerBag had a brand new micro USB that would charge the Nexus!
