I must say that I bought 10400 mAh Mi power bank for just INR 999 (which is not available on the official seller Flipkart now), So still don’t know why this product is priced so high. Asus also will be launching a cheaper, more powerful power bank soon, they have already announced it in Taiwan. It costs NT$ 449 (around INR 900) for 9600 mAh version
So think before you buy it
