Maybe I was not lucky... Delivered to me by courier March 13 (13 - unlucky number :).
Energy capacity is 4-5 times less than stated by the manufacturer. Enough for one charge Lenovo A3000 (battery capacity of 3800 mAh). Thereafter, the Bank again to be charged about 2 days! Yes, yes ... It was two days. Well, besides of the Black body of the Power Bank, and accessories for this appliance are white! Is it possible in a self-respecting company?
My suggestion - I order another more expensive Power Bank, at the time of delivery I return the Bank does not satisfy me and pay your courier difference in cost. OK?
