    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.

    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.
