    Great charger esp. for military guys out in the field. Keeps phone alive long enough to be out in the great outdoors with no electricity for a week. Good stuff.

    I have had another charger that was slow to charge, and didn't seem to work when my phone was very low on charge. This charger seemed to be as fast as my plug in charger, taking it from 15% to 100% within an hour. Had enough charge later in the day for a 2nd charge. Highly recommend!
