The usual normal working adapter. The metal case did not hold well - I glued it with superglue. Different pros: Good price. Bought for 100. - count as from China. But you don't have to wait. Got cons: I don’t understand why there is such a large rubber gasket on the MicroUSB side - it interferes with some cables. (can be cut off)
To showcase the product's features, I have added some photos to my review.
