THIS.IS.PERFECT! I cannot give enough kudos to Anker for this amazing compact portable charger! Not only is it small enough to fit in my pocket, the USB cable is long enough so that I can keep the charger in my pocket while still being able to use my cellphone! And it will continue to charge even while using the cellphone! Charging is SO quick - it took only 30 minutes for my cellphone to go from 72% to 100%! In one hour, my phone has gone from 5% to 50% with only 25% of the charger being used (only 1 “dot” of light disappeared). Very easy to see how much charge is left, and when it’s not in use, it holds a charge for a long time. I’ve left it without use for a few days and it was still fully charged when I needed to use it! Thanks for your continued commitment to quality products!
