Ambrane is one of the leading manufacturers of powerbanks. I have been using this product about a year and half and this powerbank is very useful to me when my smartphone runs out of juice. This powerbank comes with a 10, 000mah battery which easily charges three 3000mah battery phones pretty quickly. The powerbank also contains a led light which can be use as a torch in the dark. It can be simply turned on by pressing the power-button twice. Overall, this power is quite stylish and looks premium and a good value for money.
