    Not sure why, but the product would not charge Droid X smartphone. Furthermore, even when fully charged, I attempted to charge my son's non-smartphone and the Dynex portable battery would not keep its charge for over a day. If not used within that day, you would have to charge the Dynex portable battery all over again.

    I bought this for my kids tablets for long car rides. I would not recommend this to anyone. I made sure the battery was fully charged and when it was time to charge the tablets, the charge lasted for about 10 minutes and barely charged the tablet more than 10%. I really do not get what all the fuss is about.
