    Needed an extra portable charger and this fit the bill. Nice color choices and I picked blue. Charges my phone with no issues.

    I purchased 8 of these and 7 out of 8 work to charge up iPhones, adding a full extra day without having to plug the phone in to recharge. Not sure why one won't work with iPhones but it works to charge up iPads and Targus keyboards for iPads. And they're a lot cheaper than Mophie and will work with any usb-chargable device using 2 watts or less.

    So easy to use, so convenient when you are away from power sources. Works on my MP3 players, cell phone and camera! I would recommend to others, and I would purchase again. It also recharges as you play your item! Oh and great assortment of colors available too.

    I was pleased to find that it was easy to keep with me and found I had a need for it soon after buying it. It holds a charge for quite a few days and provides a reasonably quick recharge for either my android or my kindle.

    This charger is convenient and reasonable priced. It's compact size makes it easy to fit in my purse or pocket. I use it to keep my phone and Ipad charged while we are on the go since I do not have an adapter that works in my car. I wish it came with the wall adapter though.

    I found these on sale around Christmas time. I bought one for 3 people and one for myself! I love the idea of having something to charge my phone if I find myself without a typical power source (electrical or car) I have it all charged up in my purse whenever I might need it! I haven't actually needed it yet, but I like knowing I have it in case. I will update my review once I have used it!

    This item came in handy when I needed it. Charge it up keep it with you when your item needs that additional charge. It charged my cell phone back up to over 85%. It may have been able to charge me up to 100% but it had not been on the charger for a few days. The only down size if you want to call it, is that you do have to recharge it regularly. Even if you don't use it, you will still need to at least put it on charge ever so often because it will loose the charge.

    I bought two of these a few years ago after I noticed my cell phone kept sucking the life out of my battery while I was on vacation. I felt like I spent most of my days just hunting for an outlet so I could plug my phone in! So not a problem now with these fantastic batteries! Charge them overnight and throw them in your backpack/purse and you're good to go. Great size and the bright color means they're easy to spot! Definitely recommended!

    I saw this item as I was checking out and inquired about it with the register agent. He mentioned it was a great product and seemed to be a popular one, as well. I needed something like this for future travel. I've been testing it out in the meantime and it works well. The only downside it that it won't charge an electronic much more than 35%-50% of capacity. However, it's plenty to get a person by until they can get to a plug-in.

    Purchased this out of a bin of other chargers, and just got it as a back up, without any real thought to quality or anything. But I've used a few times now, and I have to say that I am very impressed by it. It has been able to charge my Galaxy S3 Quickly, and on the fly. And it's able to hold a pretty good deal of a charge. Very impressed by this charger. Couldn't be happier.

    I only purchased this because there was a deal for buying 3 phone accessories. I am so glad I did. I never knew I needed one of these, but now I can't imagine not having it. Works great. Charges fast and one charge charges my iPhone 6 from dead to almost full. I use it on the go and even in my house when I don't want to be tethered to the wall.

    So Far So Good

    This reviewer received promo considerations or sweepstakes entry for writing a review.

    I had just started a new job and realized that I could charge at home and in the car with no worries, but I was depleting my battery so much at work and while on the go, that it was taking forever to recharge my phone, once I was in the car or at home. Also, I was told initially I couldn't plug my iPhone into a USB on the work computer, and I wasn't climbing under the desk. So I thought this would be a perfect fit, because it could recharge itself at work, in the car and at home. Plus it can save my phone at work to recharge or when I am out an about away from outlets, so when I am near a normal recharge option, it takes less time. So far it works as expected. Only thing I added to using this, was I ordered a 6 inch lightning cord for my iPhone, because my OCD couldn't handle all of the cords all over my desk, between a normal lightning cord, the cord to charge this battery and my apple earphones. It charges quick, it lets you know when its full to stop recharging it by turning the LED green, which turns blue when charging a phone or turns red when recharging itself. So fixes my problem, plus it was on sale with the added use of a $5 BB GC, made my decision. Plus purple rocks.

    I have not used or even opened yet since the connector does not fit my Samsung Galaxy S5 despite the description stating that it does, so I would have to use a connector cord I already have. I would recommend truth in advertising when making compatibility claims so as not to lead buyers on to encourage a purchase. I am hoping it will work with a substitute cord. Have delayed while I was trying to make a decision as to whether to keep since the price was very reasonable.

    No, I would not recommend this to a friend

    I bought two of these so I would have a backup for when standing in the long lines at the local theme parks and my kids would run the batteries down on their phones. I have been able to recharge one phone 2 to 3 times off of each charge of the battery pack. Excellent product for the price I paid.

    this was a very good buy on sale -- I use it primary to charge my iPhone when out and about. Charges fairly quickly and provides an added sense of security when I've forgotten to charge phone the night before

    For just over $20 I never have to worry about my battery running out. I can charge it while I sleep, pop it in my purse in the morning and I'm good to go all day. If my phone battery is running low, I plug it in and keep working! Great!
