I have bought this powerbank 2 weeks ago. This powerbank is good at charging my mobile but it takes long time to charge its own battery. Battery life is not good. Design of this powerbank is poor it is very heavy to carry in our daily wear pockets. Durability is also very poor, when you charge this to 100% it only charges my mobile only for 2 times. Dont buy this. Waste of money. It is no value for money.
