Customer Review

Battery comes with a pouch and two cables (1 long and 1 short). The cover can carry the battery and slide it inside your cable to connect your device to the battery.
The product, in the image of the brand, gives us here a clean finish, simple and effective. It consists of a black box circled with a gray band on which are present 4 blue LEDs. These 4 LEDs are indicator of the remaining battery level. Just press the button to light it.
Now about the power of the battery. The 16000 mAh guarantee up to 10 charging me my phone (Iphone 5S) and 2-3 of my tablet (iPad mini). This gives you a significant extension of your battery, especially for long trips or if like me your phone does not take the whole day for daily use allows me to charge my iPhone every day and keep the week before charging my battery.
I leave my battery overnight on my computer (charging time probably less a night) and it is again full.
The device integrates a new technology "Ismart +" intelligent that detects the connected device and optimizes the charging time.
Possibility to connect two devices simultaneously without reducing the capacity of the battery.
there was also a light that activates torch holding the button but I share the interest for my limited knowledge that the first goal is to recharge.
The total weight of 320 g is a bit heavy but placed in a bag, it's going. More the autonomy present here compensates the mass of the object.
