Portable A/C unit
have a Camper Box Truck with a 14' box. I also have a 10,000 BTU portable A/C that uses 1200 watts / 10.8 amps). I would like to run the A/C for several hours without a Honda type gas generator. ...

BTU "British thermal units"
when comparing with electric heat 5000BTU, that is approx 1500w
BUT when comparing with cooling, it is not a linear transfer
its all about compressor efficiency, condenser and evap coil sizes etc..
10000 btu cooling does not need 3000 watts power
the 10.8 amps sounds correct, and runs on a normal 15a 120v home circuit
still the LRA of the compressor comes into play, and the ability of the inverter to supply this FOR the "Seconds" needed to start the compressor
the surge rating of many inverters is listed in Micro-Seconds or Milli-Seconds, not real Seconds of time
not enough time to start the compressor on most A/C units
you can hear a compressor start up on a strong enough generator or shore power, thats because it takes time to spin up against coolant pressure, its not blip like flipping a light switch
an inverter that has a surge time that is a mere BLIP won't start the a/c compressor
yes there are inverters that can power your a/c,
you may find the project costs more in time and money than you think
