    I needed a battery back-up for those days I can't charge my cell phone (away from an outlet). This is light weight. Carry it in my purse or pocket. Gives me the charge I need to finish out the day.

    Bought 3 of these online for christmas gifts and all 3 did not work very well. I had to take them back to the store and get new ones. The new ones work perfectly fine and charge my phone very quick

    It was very useful when my power was out and I needed to charge my cell phone. It is also very useful when I'm running out the door and forgot to charge my phone

    Mophie is one of those items you don't need everyday, but you sure are glad you have it when you do need it! It is small and compact to put in your pocket or purse, so you can take it with you where ever you go!

    These are great chargers when on the go & no access to a power source. With our iphones, we can usually get 1 full charge from this mophie & a partial 2nd charge (before recharging the mophie).

    This external charger works very well. Great to have on trips such as amusement parks or the lake. It holds a charge for a long time, and it charges devices in a reasonable amount of time

    This is a nice package and does what it needs to do. I like the on/off switch as it cannot be inadvertently turned on in a pocket or purse. I got this for my wife and her only negative is that it is a bit heavy. This is the price for power!

    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!

    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.

    Recharges effectively. Does not hold a charge long if unused. I charged it fully and then a week later went to use it and it was down to 50% of a charge. Need to check it regularly if you are only going to use it intermittently.

    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.

    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.
