    The item works very well. It is great that I don't have to look for a plug when I am out. It is easy to just pull it out of my purse and charge my cell. Love it

    This is a very inexpensive backup battery system for your phone. It is easy to charge and use with your phone. It would be cool if there was a cord keeper so that the cord does not get separated from the battery.

    I purchased this because I work long hours away from the ability to charge my phone. I never actually got a full charge out of this product. I would have returned it if I still had the packaging.

    For the price it's perfect in case of an emergency. Bought two of these for my wife and daughter. They always seem tohave a dead device or very low when they need it the most. This took care of that issue.

    This charger had saved me many times. It's great when you're away from an outlet but need to have your phone. I have taken it to my kids all day sports tournaments and the amusement park. I highly recommend.
