True air drying reqs an air-conditioning type compressor, I believe.
246 watts seems kind of low, but is possible. Might not use a compressor.
Cold outgoing air may not be a sure-fire test, what with the joule effect of
expanding gases'n'****....

Proly the unit should be rated ito cfm at some psi..

The real test is if any condensate is produced.

I bought a used compressed air dryer for $10 last weekend. Tried it
and found that it was working, since the outgoing air was cold and the
release valve was functioning. My question is about capacity. This
dryer uses about 264 watts of power, according to my wattmeter
(kill-a-watt). Is that enough for a 3 honest HP compressor. Thanks.

1 HP/hour == 745.7 watt/hour

But, um... how many watts does it take to dry air?? I dunno.
