    This item is perfect for the ones who use smart phones and as we know the smart phones these days are not lasting with battery life. I'm using it and it fully charges my phone multiple times

    Holds a full charge for an iphone so when you're away from an outlet you have at least another full charge.

    I liked it for the fact it worked really well for charging my girls iPods without an outlet to plug into. If they are happy I am happy

    My grandson can use his phone in school and the battery was draining almost every day. Thought we would try this. Gives him another full charge for his I phone 5 and it was a good price.

    I purchased for my niece for phone and I am not sure if it has to compatible to certain phones but hers was not one of them, the charger stop charging the phone ( it seems like it was a shortage in it). I wasted my money..if Best buy wasn't so far from my home, I would have taken it back but it wasn't worth my gas going all the way back to Jacksonville. I probably would have spent more in gas so I just took a lose...

    this little device was a life saver when my son's tablet started to lose power on a road trip. It definitely is worth the price.

    It is definitely nice to have one full recharge for one of your devices. Make sure it is charged before you take it with you. It will lose its charge if not used after a few days.

    I love the green one and it held a charge (so far that I have seen) for 1 week. The phone was charged from 10% to 65%. I think that's pretty good for being in the car for a week.

    Like having this because I can charge my phone at work, in a store or even at a game my kids play at while taking pictures my battery will not run dead... It's really convenient.

    I bought 3 on sale, and they look great and charged quickly. I loved them, but much to my chagrin, they will not work with either my BlackBerry nor my MIFI Liberate wireless hub. Both think they are a USB input, not a charging source. But I gave 2 of them to my son and they work GREAT with his Samsung S5 Active, and the 3rd will go to my wife to try with her iPhone. BTW, I hate iPhones!

    All you need is your phone charger with USB and your good to go. Can charge phone a couple times before recharging. Great if your on the go and can't plug in !!
