Sony PB574SJG 10000 mAh (gold) - I purchased this product after 50 percent discount for Rs. 1500 from flipkart which i found a nice deal . The design was fine in the picture . But when i saw it in real the gold color looks really dull . I did not like it by looks but then i overlooked this drawback . And when i used it i got highly disappointed . It did not worked well for the first time and after my second use it stopped working . It was not charging properly plus it got dicharged very quickly. It was with no warranty . I regret my decision of purchasing it . I should have reviewed about it before purchasing and not just ordered it by seeing the discount and brand . A complete waste of money . They are fooling you . It does not work like what they promises . They say it work for 3 to 4 times when once fully charged. but this is not true , it gets discharged after one time use . Plus this power bank does not have the specified battery strength . Do not purchase this product at all . You will get highly disappointed .
