Today’s phone batteries are no longer those of once upon a time! But despite the obvious technological advances, even the latest generation smartphones endowed with batteries that exceed 3000 mAh don’t always manage to last until the end of the day. To solve this problem in the routine of their co-workers, Nana Bianca proposes its innovative Power bank. Covered with blue silicone and decorated with stars, its main characteristic are the small suction cups which, besides giving the product an original appearance, allow it to adhere to the device thus allowing you to save space. This model, equipped with both a USB port and a micro USB port, has a capacity of 4400 MAh and comes with its own usb cable. Compatible only with Android or Windows Phones, not with i-Phones.
