Finally ran into my kill-a-watt
my fan draws 29 watts regardless if it is blocked from the front, the back, with a stick, or not at all. Main difference being it only does useful work (moves air) when unblocked.
My heatshrink gun on cool draws:
119 watts open
116 dead head, speeds up a little
114 intake sealed, speeds up a lot
so fairly close readings all the same.

Interesting observcation. Do you think it would it be fair if power were measured by a kill-a-watt? I'll have to try that when I get home, both in cavitation and dead-head mode (lay it in the floor). |
