i.e. not Open Source. What a shame.
At least they provide full schematics here, which is better than many other products do.
C64 PSUs are C64 killers, which is why I feel strongly there should be as little as possible in terms of barriers to getting a replacement.
Yes, it is far better than the alternative (no schematics), as at least we can learn how it works without reverse-engineering, as well as build our own legally (just not sell).
Without USB-PD (or similar technologies), the max power over USB is limited to 10W (- wire loss), so it would not be enough to power C64 reliably. So it was included in the name.
So I am pretty sure that "PD" in the title has nothing to do with public domain.
