    Battery is inconsistent

    I've experienced very inconsistent charging results. Some days it can charge my iPhone 6 from 20 to 80% and other days it only supplies charge from 20-35% before dying. In all instances the battery is left charging over night. It could possibly be my iPhone, but I highly doubt it.

    I had to exchange 2 of the ones I purchased because they would not charge properly. I believe there are variations of quality in this particular product and I received ones that were not working well. They were Christmas gifts so it made me unhappy that they did not work properly.

    this item WAS a stellar pack. but if you buy it on the $9.99 clearance price you will get an aged unit with bad cells. both that I ordered ruptured cells inside on first charge and are useless.... won't send back bc of the 6.99 return shipping fee... have to eat the loss.

    I have had several portable chargers and for me this one falls at the bottom. It seems as if it doesn't hold a charge for too long. Others that I have can hold a charge for months if not used but not this one. I wouldn't recommend relying on this on in case of an emergency.

    Product looks good and when paired with a short lightning cable it's easy to slip in a pocket, but the charge life seems to be short on my unit. A fully charged battery can be out of juice within a couple of days without it even being connected to my phone.

    Definitely doesn't charge like it says it does. I wouldn't recommend on a trip. Maybe for when you go with your mom to the store and she leaves you in the car type deal.

    Didn't take long for me to realize I had a lemon on my hands. Right out of the box, it charged without a problem. But it would never take my iPhone 6S past 20-35% charged. I attempted to charge it with 3 different charging wires, and 3 attempts at discharging and regharging the Mophie. Fortunately, I called Mophie immediately. They determined i had a faulty unit, and they replaced it free-of-charge with their up-to-date version. The second unit charged my 6S immediately. I even got three phone recharges on one charge up of the new Mophie. Thanks, Mopohie

    I bought this on a flash sale! I'm so excited to get this. Because other brands do not charge very well at all. And I have heard great things about this brand!!! Super excited to be able to charge my devices on the go!!

    Doesn't seem to be 4000 mah, more like 3000 perhaps. I don't think output voltage is user- selectable either. It supposedly switches automatically depending on the device that's being charged.
