    I bought this for my parents for trips with their iPad and iPhone. This was a good value for the amount of battery life it provides. Something a little smaller would be perfect if it would still have as much battery power.

    It's a good charger for your money. Not a fast charge but definitely enough for 2X charge. The best trick is though to put your phone on airplane mode for a fast and lasting charge.

    Works really well, but ugly and a bit too expensive. Still, good to charge your phone a couple times if you won't be near a charger anytime soon.

    The battery works as expected. The charging cord is a little stronger than a cheaper competitor's power pack cord, but I still feel that this may be a future failure point.

    It worked for about a month. It was a great product for a reasonable price (after the sale and coupon), then it completely broke. The return policy here is terrible though. Make it at least 30 days.
