Indeed, this beautiful battery the size of a external drive 4-5 times recharge a smartphone.
Its 2 USB ports iSmart can charge 2 devices very quickly.
Very handy when lon is moving a few days or sil was no desire to stay glued to power outlets!
The integrated lamp is more to help in an emergency.
For increased capacity to equal size and weight, there is the 16000mH battery.
I recommend this product!
