We both agree that an AC VA is a watt just as much as a DC
volt time amps is a watt.

I found out later that the 40Watts is almost certainly a lie or
a misprint, since the same part number "HC363-5U" also fits an
exact duplicate looking device, only under a different brand
name, but with the wattage listed as a more reasonably close
35Watts to the calculated 34 Watts maximum output.

So, the input AC power factor is just a red herring, totally unrelated
to anything being discussed here.




And the difference between 35 and 40 W is so small as to be irrelevant too I
suggest.


Um, at 5 volts, wouldn't that be 1 amp? ヽ(€¢€¿€¢)ノ
