I bought It in the month of November 2017. It's bettery life is very good. It's capability of bettery life is 10000 mah.
It's takes a lot of time to fully charged but it can change two types of devices in one time it is very nice for me.
It's design is not very much good. it is a ordinary power bank.
I payed for it 800 rupees, so I think it is not a big deal. It is not very much costly that's why it is a value of money product.
I using it from round about eleven months. It not create any type of problem like for repairing. So, I will say that this is a durable power bank.
In the end I recommend you to go for it.
