I bought this power bank 5 months ago from flipkart only for 30$ . This battery has a wonder ful power back up of 5000 mah battery . It is a light weight sleek design , slim . It can easily fit in your bag or pocket . The sleek design doesn't let you feel that there is a power bank you are carrying along its just like a another mobile phone . Its not at all heavy .
This power bank is capable of charging a smart phone up to 1.5 times or approx 2 times . Which will provide you 19 hours of talk time and 11 hours of browsing .
In this power bank there is a universal power port of 2.4 A which gives very fast charging . You can use it to charge your phones, camera, laptop, speaker and many more .
This battery has got efficient battery cells which provide maxximum output of power which is also extremely safe during the use and there is no harm ful effect on the user .
There are various types sensors which checks the heat , voltages , over charging and circuit shortages which directly shuts the battery and stops the case of accident .
On the side of the battery there are 4 led indicators which tells the level of battery level of the power bank
Thank you
