the item is good. build quality is great, and it just looks beautiful. it is kind of heavy, but it also has a big charge capacity. the only issue I found with it is that, it takes for ever to charge this power bank. it is provably due to the large capacity, but it is still a long time. I'm talking about 5 hours, and it only charged 4%. that's a really looooong time. that is the only down side to this product.

it got here super fast, central turkey took two weeks to arrive. it is as described, it involves a cable and the powerbank in the box. the cable is high quality and the power bank charges my 2800 mah phone more than four times with even if the power bank is half full. it weighs more than my phone but it was what i needed. it takes 8 or more hours to fully charge. never gets hot even while charging. takes about one and a half hours to fully charge my phone. im satisfied thank you.
