I was not aware of a product like this untill I saw this suddenly in my recommended list. When I saw this I was wondered by the size and immediately I ordered, even though I already have 4 power banks this is something different because of its size.
It is very small in size, thanks to polymer battery and very light weight. I bought it for 278 rupees plus Flipkart coins, so I feel it is a good deal.
It has enough grip like the usual Flipkart 10000 mAh power bank.
