This weekend I measured the actual power draw on
our Cool Mate CLM12K (12,000 BTU) air conditioner
and found that it was drawing 12 amps at 124V AC
instead of the 9.1 amps claimed on the Dometic
website.

Is there something wrong with my unit, or is it
just a case of "specmanship". I'm wondering if
the spec sheet power may be for the unit itself
without the necessary sea water pump running.

12 amps is 33% higher than the spec.

Anyone know?
