When I measured the A/C power draw it was 12 amps
Your A/C might be different
My Dometic 13.5k BTU draws 12.5 Amps continuous, but pulls 20 amps at start up, with a fully charged battery bank. So you need to get your charger out of bulk charge mode before you attempt to start up the AC if you pair an Eu2000i with an Eu1000i to get the AC started.
I don't think it's a good idea to run an AC off of a single Eu2000i once started, that air cooled motor works too hard to keep the AC and fan going, far too close to it's 1600 watts continuous rating.
