An external battery handy for chronic users of smartphones / iPhones. The battery has a high capacity but still a little bulky and a little heavy for a pocket, yet it is lighter than other external battery models. The charging time of the battery itself is a little long. However, once charged, the battery can supply several times a smartphone or iPhone (depending on the type, see the tables provided in the manual), which compensates the charging time. Blue LEDs indicate the charge level of the battery and when to think about recharging. The great advantage of the whole, this is the Ismart technology that allows the battery to identify the connected device and load it automatically as needed on the device (if it is a different iPhone or tablet) .
