    Its a 4000mah which gives us about a full plus extra on Moto Z Force phones and it was on sale for $10 so it was a great value and does exactly what it should even while playing Pokemon Go!

    Doesn't give a full charge to my iPad.

    The Mophie doesn't perform to the level of my expectation. The charges don't last as long as tradition direct charges. I cannot fully charge an iPad. It doesn't have enough juice to fully charge any device more than once. I thought it would have more power and capability than it is demonstrating.

    I have Samsung Note 3 and this device could not charge it all the way. For the money, it probably works well with a smaller phone, but did not work with mine as well as I wanter

    When my daughter's phone battery would die while she was out, often times there was no where to plug it in to recharge it. The Juice Pack has come in handy several times, definitely worth the money.

    The portable charger is an excellent product to have. It charges fast and it has a full one and a half charge for my iPhone 7 Plus. It is simplistic and I use it as often as I can.

    Love it we actually have 2 of these we take them everywhere we go to keep our stuff charged when we aren't close to plugs. Stays charged and keeps my iPhone and iPad going when they run out of juice.

    When fully charged can recharge my iPhone 7+ twice, but it doesn't hold a charge itself for very long. Was hoping this would help with charging my phone during camping trips but the charge drains too quickly.

    I like having a battery like this just in case. Sadly, this is my second Mophie battery that has worn out in under a year. The amount of charge remaining is unpredictable and will say it is full, but dies out after only supplying the phone with 20-30% power.

    I was more concerned with a compact form factor than anything else and this mophie fit the bill. Nice finish too. Good for getting you through a day without access to an outlet.

    This unit's size is perfect and can charge my phone to 100% when my phone only has about 10% charge remaining. Small enough to carry in a car door pocket, glove box or console.

    This is my third Mophie. I've only had trouble with one, and the factory replaced it for free. Very satisfied with them. It's nice having a handy power source where plug ins aren't available.

    This is great for on the go. Helps battery stay charged all day for my Samsung Galaxy s5. Also, if you don't use it right away, the mophie holds a charge for a long time. Absolutely love it.
