Hmm. If you reduce the power to the compressor motor surely it will
just run longer to achieve the desired temperature? And likely with
the motor being not as efficient too, since they're designed for a
sine wave. Then there will be the heat produced by the chopper inside
the magic plug.

I was sceptical until I saw them in use in a supermarket, (Iceland I
think)

Oh I'm sure you could improve the efficiency of a basic freezer. But I'm
not convinced it can be done with a plug in device.
