As my cellphone battery was not so good, and I used to travel 26 km to my college, I needed a power bank so that I could keep my phone charged.
A year ago I found this power bank on flipkart.com for 699 as it as 11000 mah I thought it is a value for money offer and quickly bought it. When it reached me, it had a matt black finish with a grey border, it was heavy and the chord which came with it was tiny so you can’t use it at a distance. The plus point it had that it comes with 3 USB ports so at a time 3 phones can be charged with it, also it has a LED which can be used as a torch when in need.It also has a 4 small LED light setup which shows the amount of charge it has and these lights blink while it is charging.
First it was working nice, but after a few months its capacity decreased, it charged less then previously it did, I was okay with it but after a few days, the charging port of the came out from the power bank, it was totally broken all by itself.so i was disappointed with the power bank.
