A spec sheet giving "current" in "amp-hours"?

You mean the one that footnotes as "Average current consumption for 12
VDC systems over 24-hour period"? So you think it would be more
useful to say "sometimes 4 Amps, sometimes less"?

Describing current in amp-hours is stupid. Defending it doesn't look so
good either.

A spec sheet for a heat pump ... that doesn't give the heat pumped?

Yes, BTU/hour would have been handy.

Handy? How about less than utterly ridiculous.

CO2 as a phase-change refrigerant? Critical point, 88 deg F, 31 deg
C. Could a boat cabin get that hot?

What's the problem?

Physics, thermodynamics, that sort of thing. Supercritical fluids do
not change phase. CO2 is supercritical above 88 deg F. The author of
this gibberish is either a fraud or a fool.
