I have purchased this powerbank 3 weeks ago. I will share my total experience with this powerbank. First of all, the powerbank needs a lot of time to charge its battery. The power consumption is too high and it gets heated when it is charged or discharged. And the output from this powerbank is not good enough to charge my mobile at a good speed. The battery life is very poor it charges my nobile only twice even with a 100% power in it. It is very heavy to carry and inconvinient to put it in pocket. The design is very poor and the durability of this product is not bad but could have been made better. This is no value for money. Please dont waste your money. Instead buy some other product from a branded seller.
