From making an order at book my offer and delivered via e-com express on 14.06.2016.
It is not working properly since the day it has been delievered. It shows that itbis fully charged by flashing 4 led lights but when i charge my samsung gt-s7582 phone which has just 2500mah battery it is not even charged half and the battery goes down i have charged the power bank for at least 14 hours but still the same problem.
Sir, i want the refund for this product and please take some remedy actions on that company legally or else i want the original power bank with the same company with the warranty certificate.
Ir please take an action immediately on that website and power bank making company.
