If we assume an efficient 5K BTU/hr AC unit with an EER of 12, and we assume an inverter efficiency of 95%, then the steady state power usage is: Power to AC = (3000 BTU/hr) / (12 EER) = 250 watts, or 250 / 0.95 = 263 watts from the battery — this is about 22 amps on average from the 12 volt battery.
