As in today’s generation mobile is the most essential tool for everyone and whenever the battery of our mobile phones discharge we go for power banks so that we could again charge our mobile phones battery . Only Due to this reason only I purchased this Billion Power Bank 15000 . It was one of the worst decision of mine that I purchased this Power Bank . While I was purchasing this Power Bank online I read its discription . It was mentioned that it is of 15000 mah but when I used this power bank it was not more than 9000 mah . It takes around 3 hours to charge my mobile phone . When I charge my mobile phone with this power bank my mobile phone always gets heated . The only thing which I like in this power bank is that it is good in terms of looks and it looks attractive due to its shiny colours . I purchased this Billion Power Bank at a very high price . Overall It is totally waste of money . Many Power Banks are a better options that can be purchased rather than this Billion Power Bank at same range . It is not durable at all . This power bank is not at all value for money too . Thankyou all . I suggest you all to go for any other Power Bank rather than this .
