This is the sort of thing that almost (but not quite) pushes me to support mandatory certification (enforced by patents/other IP protections) for consumer devices that use a familiar connector like USB.
Consumers shouldn’t need to worry about the specific output voltage; the presence of a USB-A connector should indicate that it abides by the specification.
The hacker in me hates the idea of enforcing something like this, but poor interoperability is such a pain that it would be nice to have stronger guarantees.
