Bought this around 10-15 days back from rediff shopping.
Spent rs 1430/- for the same which i think is reasonable.
It is specced at 10400 Mah.
Have been using it for some days and here are some points to note from my side
1 Its a little heavy around 250gms
2 Has a metal body
3 has a 2 amp and a 1 amp port so two phones or phone & tab can be charged simultaneously.
4 has a backlit LED showing charge %age which is not at all accurate
5 Has a single button on top which is a little erratic ( sometimes requires 2-3 presses to switch it on )
6 Tested it twice with my phone and it was able to charge my phone 3 - 3.5 times.
Which comes out to be 6300mah- 7350mah if calculated according to my phone's battery of 2100 mah.
7 Have charged it 3 days back and have not used it since then. It is still at 100 % .
8 came with different sockets and a cable but I am using two small usb cables for portability
9 Takes around 18hrs-24hrs to charge fully. But I have been charging it using a .5amp charger . Should be quicker with a 1 amp charger.Will check and post.
10 Takes almost the same amount ( slightly quicker actually ) to charge my phone as a normal wall charger
11 1st full charge takes the indicator to 70 % , 2nd full charge takes it to 50%, Third to about 10%
Cant think of anything else right now.
In all I think it was the best I could have purchased for less than 1500/-
