Bummer.
It's curious that they don't make one since 220V-240V is commonly used in much of the world.

I can find a Kill a Watt type 230 device for foreign markets - then you get into the whole 50hz vs 60 hz thing.

... Perhaps one of these would work.

If I use one of these to get the watts at wall that would be "apparent" power?
Do I then multiply the watts by the power supplies input "power factor"
(.95 at 230v) to come up with the "true" watts?

 

Perhaps one of these would work.

Yikes! Look at the connections to the 230V plug and the earth connection.
