I am using this power bank since last 4 months.
The battery lif is very poor as it only gives output of 3500 mah, while they have written the output of 6000 mah on box.
Design is ok as it has led indicator on body and light in weight and portable.
The MRP is too high as compared to its quality and output.
The body is made from plastic so it is not more durable and also not heat proof.
