    The Duracell Pro 510 that I received MUST be defective. I charged it for over 10 hours to get all the 4 status LEDs lit, indicating that it was fully charged. I unplugged and when I tried to use it to charge my phone a couple of days later, there was only 1 LED lit ( 20% of capacity left), the Pro510 power bank could not charge my phone (a Samsung Galaxy S3). I charged it again fully and it went flat after 2 days. I returned it to Bestbuy. Very disappointed and Not recommend it.

    Does not keep its charge for more than a day, so it is useless as a back-up, portable charger.
