    This is convenient, for travel or other times, when it's difficult to find an outlet to re-charge (for me, phone or Kindle). Recommended to me by store rep.

    I purchased this as it was on sale just hoping it would work! Well of course it works and it does a very good job of charging my phones. It's fast and charges up to 100% without a problem.

    With so many devices to add battery juice this was the best device yet. It was slightly priced higher. But definitely worth it.

    Bought this for a Christmas gift. My son opened it it only bad 1/2 charge. Put it on a home charger, after 12 hours, it still only had 1/2 charge. Brought it back to BB for an exchange. Second one works fine

    Purchases this for my husband, so that if we have a power failure, he can still charge his iPad and his iPhone. Was a great price too and came with the cord.

    This juice pack does the trick! It even stands up to charging a tablet while watching video. The 2 USB connections are extremely useful as well. Highly recommended!

    Some of these portable batteries are too big to fit easily into a pocket or bag. This one does the job with a slim profile and not too heavy.

    This is a great portable backup to the normal chargers. It sure comes in handy when there's no wall socket to be found or when you're out and about!
