    I have to say first that I love the quality of Mophie products. The problem here is Best Buy is clearance pricing old units no longer made by Mophie. The unit was completely dead when I received it. I tried to charge it 2x, and it did not charge my phone at all. I contacted mophie and under their warranty I received a replacement that works.

    I first purchased the mophie external battery several years ago and was extremely pleased with its performance. I was so pleased that I decided to purchase 2 more since they were on sale at such a great price. Bad decision! Neither would hold a charge...very poor performance. I returned both. Perhaps they were from a "poorly made batch!"

    I don't know how good the battery is overall but twice my orders have been messed up. The first time, the battery arrived in an opened box even though I ordered a new battery. Best Buy sent me another one that looked new, but it does not charge or provide a charge for my devices. Best Buy really needs to provide functional units for sale.

    I saw several people had issues with this battery but decided it must be a fluke as many had said it worked great. Well mine was dead on arrival. Simply will not take a charge and has no juice to give....so I guess this is one "Empty Juice Box". Even on sale...broken just does not have any value. Don't waste your time on these products.

    Didn't hold a charge. Plugged in overnight until all four lights blinked. Once unplugged, would immediately drop back down to two lights, and then would charge the phone for about half a second before saying no charge left. Tried on numerous occasions, also exchanged for another one with the same result.
