    Bought this product a year ago. I usually use it when I am traveling out of town. After 11 months since I bought it, it does not anymore charging properly. It will charge for about 3 minutes and it will stop. I need to reset the charger to make it working again. But again it will stop charging after 3-5 minutes. I will not recommend this product to anybody.

    Works as advertised so far. Easily recharges my phone to extend my heavy use at Disneyland Anaheim. Not too bulky. Bought on sale.

    This "power bank" charger has worked well for me. I charges my iphone rapidly, and the time it takes to recharge is also fast.
