I bought this power bank 7 months ago. I spend most of the time in my college and in my house also, I don't like to sit near the socket to charge my phone and use it. So I bought this power bank from a local store as it was told to me that it will charge your phone 3-4 times in a single run. In the beginning, I used to charge my phone nearly 3 times with a full powered bank. But after 3 months, I can only charge it for 1-2 times. Now, it feels like I have an extra burden of charging power bank. I mean, what's the purpose now of buying the power bank if we had to repeatedly charge it. Also it became hot after using it continuously so I feel frightened of it's explosion. I recommend buying other power bank than this.
