This power bank works well till to 1 month. After that things became difficult,
I bought this power bank6 months ago. I could barely charge my phone two times, although the power bank has charged fully. When I bought this power bank, the dealer said that I can charge my mobile 4 to 5 times if the power bank has a fully charged. This power bank only has three hours of durability.
This power bank needs 15 to 17 hours to get charged fully, this power bank got very hot, When I used this power bank continue to 3 to 4 hours. I suggest you Go for another power bank because I have personal experience of this power bank, and it was not good at all.
