I was using an INTEX POWER BANK 10000 mAh(White, Blue) earlier so I recommend the same to my friend. But she bought a different model from me. I never thought that same company can produce two such different power bank, one which is so good and another too bad. This product is highly unsatisfactory. She bought it for Rs. 1200 after discount which is a complete waste of money. My was at cheaper rate and with double benefits. Talking about this product, it is no at all portable. it is really big in size which does not make this product portable and not so durable too.
