We're featuring this external battery charger for three reasons. One: it's a pretty neat piece of kit in its own right, with a huge 12000mAh capacity (4-8 charges for most recent Android phones) and four USB charging ports, three of which can be active simultaneously. Two: the manufacturer made some small but pertinent additions to the hardware design after receiving feedback from a knowledgeable customer. Three: at $40, it would be a pretty good deal even for a basic 1-port charger of this capacity. With the extra features, it's a downright bargain.
The EasyAcc charger's biggest differentiator is its four standard USB charging ports ,which are set to amperage outputs between .5A and 2.1A.
