This power bank is amazing, well you couldn't expect less from 12000mAh of power right?. It can charge up almost 2 to 3 times my Samsung Galaxy S7 to 100% (the last one was charged up to 97% and the bank still had 17% power in it!). Of course, that was with a 100% charge from the power bank; the quality of the product is great, it was not that heavy as I expected which is good (200gr), remember you'll need to carry it on sometimes.
The package was great for the item, came with a white USB cable and a little instructions manual.
