    Perfect for traveling with kids. The size of the battery allows you to charge multiple items on a single charge. The only con was the speed in which it takes to charge devices... not one of the quickest chargers out on the market.

    Love that it charges great and doesn't use up its charge. Can be used multiple times without wearing down.

    The Anker portable charger has been a game changer for my long days away from an outlet. This Power banks has quite a large capacity. Would not leave home without it. Only negative is it is pretty heavy to carry in a pocket.
