This battery is roughly the size of an iPhone 5, and twice the thickness: Coarse provided capacity. In terms of functionality, the classic: microUSB charging 1A, two outputs (1A and 2.1A, clearly marked) and a four LED charge indicator. By cons, it is distinguished by its quality manufacturing with an aluminum body, and its nice accessory, a short cable type "noodle" to four outputs (microUSB, microUSB 3, iPhone / iPad former and latest models) that can also be used for charging. A pretty cloth cover is also provided. The capacity is sufficient to fully recharge an iPad mini, or about 80% for an iPad Air, a handy accessory for traveling or camping, and always keep gadgets in his bag. On the crowded market of batteries this capacity, the FP10 is distinguished by its small size, quality of construction and multifunction cable. I recommend it.
