Hi Friends
I am sharing my own experience about sony power bank. In market there are many power banks available by providing many features and great mah but these are not actually what they say. Their feature is approx 40 percent wrong. The only company that provide all features and quality exactly is sony power banks. What they say is actually available. Its only price is just little bit high than others. But what they give is apperciatable. It is light in weight and long durability power. Whatever the money they take, they value them by providing quality. Exact mah is privide by their side. It is mostly design in square size thats look pretty wonderful. Charges all types of devices under its power.
