    My phone has pretty good battery life but I was going to be spending multiple long days at an event and wanted extra piece of mind since we need our phones for so much these days. It's small enough to take along easily and works well to charge. I use it at home a few times a month just to make sure it works when I actually need it.

    Poor quality, this thing I tried to charge for over 18 hours and it still was only 3/4 charged. I boxed it back up and sent it back. It’s pretty heavy too for the size. Good idea but doesn’t hold a charge itself.

    Does not work with my Apple iPhone. It won’t give a charge. I will have to return it to the store. Very inconvenient . Looks are deceiving. Looks and feels great, but does not help if it doesn’t charge your phone.

    It takes forever to charge itself and stops charging my phone at the slightest movement - just what you don't want in a portable battery. Bad design all the way around.

    My wife needed a phone charger. We chose Best Buy because of their sales force and inventory. Very pleased with our purchase. Maybe now she will leave me alone.

    Great buy for the price

    Simple, and basic, but does what you need it to do, and the price is right. Sure, there are other portable charges out there, that may have more features or a longer battery life and more charging capability, but their price can be more than double of this one. Great buy at this price
