    My son always has a dead phone....so this was a perfect Christmas gift for him! Hopefully he'll remember to charge this back up battery, unlike his phone! Lol! He loved the slick design of it.

    The first power station I purchased would not charge, so I returned it the next day and got another one. The second one is doing fine. It's great to be able to carry around extra battery power.

    This is a quick fix for a quick charge. I use mines when I'm 30% or less. After I plug it in it quickly charges to full battery. That's it. Not a long lasting charger but it'll get you by.

    Good value for money for such a long battery life product. Only inconvenience is you have to take your iPhone charging cable with you wherever you go. Would be better if it came with its own unique cable.

    First one I got was doa but exchanged it at Best Buy and the second one works fine. Only get one full Iphone charge. But good for a quick charge on the go when no Power is available.

    First battery I've ever bought, worked well...

    This is the first and only external battery I've ever purchased. With that in mind I got it to bring with me while doing the MS 150, to keep my phone charged while I used it as a bike computer. It worked well and only had to charge my phone once. I like the medium size of this one, was worried about the storage capability of the smaller one, and the size of the larger one threw me off. This was a happy medium for me, hopefully I use it more than once a year.

    Have used this numerous times to charge my cell getting a full charge, in fact 2 charges +. Great for emergencies, vacations, travel etc where there may not be an opportunity or place to charge up. Maybe a little heavy for purse for everyday. Use a smaller one then, but overall a great product. Bought an extra as a gift. Don't have to worry about a power outage, this battery stores the charge for weeks at a time without loss of charge. I think it may have been several months, actually. Always ready. Great peace of mind.Have not tried charging 2 things at once.

    The price was right so I gave it a try; I was amazed how fast it charged my I-Phone on a recent trip with enough left over to charge my I-Pad!

    Used this on my HTC one and didn't get great charging results, but I let S friend use it with his iPhone to see if the charger was defective. iPhone charged really well on it.

    This is the second Mophie I've bought. This one was a gift for my father-in-law. I bought the larger one for myself because it has the extra port and I have kids. They're heavy but worth it when you don't have an electrical outlet around.
