    I love this power bank! It's small enough to fit in my mini bag with my charger, yet it holds enough juice to charge my iPad! Best purchase ever! I'm getting my brother one for his birthday!

    Bought to charge phone on two day backpacking trip. Was lighter and smaller than solar charges. Works well will charge my Galaxy S5 two times and does so quickly. Very happy with purchase.

    I bought this for use when riding ATV's. It was great and charged my cell phone quickly. I have a bad cell battery so the charge pack came in handy and gave me more than a single charge.

    I bought this before going to disneyland. I needed a full battery to record a proposal that was going to take place. Not only did it charge my phone, but the other 3 phones in my party.

    This little guy is awesome. It charges at up to 2.4 amp for my phone, ipad or anything that uses a usb cable (really fast). I even charged my camera with it. 6000ma is a big battery for the price. You can't charge more than 1 at a time, but for this price I can buy two and have 12000 ma. Small and lightweight so it is no problem to carry round. I'm probably going to grab another one for our next trip just to be sure (longer flight).

    Got this before a trip to Puerto Rico, thinking it would be helpful in our travels, and was I right - it charged both of our iPhones and an iPad before finally dying... seriously useful, and a great size makes this an easy travel companion!

    This is perfect for when I'm on the go. It charges easily and I get a couple of hours out of each charge. I like that I can charge my phone and other devices using this. The only downside is that you can only charge one device at a time.

    I was in need of a new portable charger when the one I had would not even charge my iphone 4s to at least 100%. This charger met my needs and the price was good. The first time I charged it, it took more than 6 hours. So the second time I charged it, I plugged it in before I went to bed and woke up to the charger fully charged. Charges my phone 2 full charges and a 3rd charge up to about 50%. More than a month later since I purchased this charger, still holds a good charge, 2 full charges and a 3rd at about 50%.

    This charges the phone really fast. As an added bonus, it has a mini flash light which helps you see when plugging it in the dark.

    I travel and never know if its going to be a busy phone day or not. So to have a battery backup/charger is great. Works well and fast. Also will charge my bluetooth tablet gps.

    I was looking for a small portable charging device such as this one to charge my Samsung Galaxy S5 on the go. It's small, so doesn't take up too much space in my purse and it works very well. It does only charge my phone once completely before having to charge it up again. So if you're looking for one that will charge you phone more than once before having to recharge it then you need a larger one!

    It can fully charge your phone battery in a fair amount of time, small to carry in your purse. It comes with charging cord.
