Some of those are legitimately good brands (Anker and RAVpower being two I'm personally familiar with). Anker has even grown in North America to the point of having distribution within physical stores such as Sam's Club[1].
That said, your point still stands. These are not household names in the North American market, and it's not immediately obvious what is a legitimate and reliable option vs. a throw-away brand selling imported fire hazards.
