It is not a useful power bank. It has two USB ports and one micro port to charge it.
It take very much time to charge it self and also to charge other devices. Nowadays 10000 mAH is nothing to charge a mobile or other products.
It has 10000 mAH lithium battery .it comes with a small power button and some blinking light to indicate charging.
It gives 5v 1 ampere output capacity. It's structure is weak if one times it fall then it will break or destroy.
The main widrawback of this powerbank is that it cannot charge a 3500-4000mAh battery fully or quickly.
It charges very slowly slowly. It can't charge multiple devices quickly and totally full. It is a bad product.
