    I had it on the plane when I went to Hawaii because I thought I might need it. As it turns out I didn't then, but I have used it to charge my iPhone and iPad and it worked just fine! My grandson recommended it to me!! I think he thought he might need it.

    Works well, but it does take a while to fully charge this little thing. Will charge an iphone 6 but the 6plus will get about 80 ish percent. Very light and portable. Can put it in your pocket and wont be much of a problem.

    Love the fact it's light weight and small with lots off juice to keep your phone or tablet charged when on the go and no outlets near by.

    Thoroughly enjoy the freedom from concern this offers as I took it with me on my most recent trip. Happy to not be one of the many travelers who had to find a power port in the airport. With a full charge it can successfully recharge my S5 twice.

    The Mophie does what I need it to do when it's needed. It's small enough that I carry it in my purse all the times. Just be aware, however, that even if you haven't used it, the available charge starts to diminish over time. You should periodically check to see that 4 lights appear when you push the button (silver part, right hand side opposite the word Mophie). If three or less appear, I would advise charging the device. Also make sure to carry the charger chord to the device you want the Mophie to charge. The Mophie chord is only for charging the Mophie and needs to be connected to a plug with a USB port (does not come with device). The Mophie USB port can be used with both Apple & Android charging cables

    This tiny gadget is the best yet. It keeps my phone charged when I need it. The only thing is try not to use you phone or tablet when charging it because it will drain the battery.

    This was the first battery charger I have bought. I needed one for my trip. It quickly charged my phone. I did not have to use it more than once during a day, so I cannot say how many times it will charge. However, it did what it is meant to do.

    We got these as gifts for our nephews. They loved them. I own 3 personally and they are handy to have around when you can't charge your phone/iPads with your regular charger.

    If you need a power pack for travelling this is it! It can easily charge my Nexus 5, my iPhone 6 and my iPad with a single charge! Great for when you're away from a switch.

    Bought this for a trip to Disney so we could charge phones in the park without having to hang out by an outlet. Was able to connect iPhone to charger, place in my backpack and have a fully charged phone in about 20 min.
