The only way it would be counterfeit is if they sell it as an Anker product or print Anker on the product.

My assumption would be that the same factory that makes Anker products is also selling the same designs to competitors - it's also possible that a different factory just cloned it.

Note that even if it's the same factory, they could have different quality control for different clients. So quality can differ even on identical designs.
