MicroAir hard start system and a Honda eu2200is?

Has anyone used the MicroAir A/C start system with a 2000-2200 watt Honda to start/run their A/C? I have read that this can allow a higher BTU (13.5k) A/C to start from a smaller generator, as the inrush current is handled by the MicroAir product, and not dealt with by the generator.

In lieu of hauling a 3000-3500 watt Champion inverter generator on a front bumper cargo hitch, would a single 2000 watt generator suffice for most truck campers? This is assuming little to nothing else is running, other than perhaps the converter.
  • That is impressive. Running a 15k BTU/hr A/C from an eu2200i without issue?

    That is the difference between having to have a front bumper hitch for a 3000 watt monstrosity versus something you just shove at the front seat, with an extended run fuel tank strapped to the roof.

    How well does it run from that?
  • I have it installed in a Coleman Mach 8 15,000 BTU AC and ran it with my old Honda 2000 and am currently running it with my NEW Honda 2200.

    I would recommend that you figure out a way to turn off the charging part of you campers charger/converter as you do not want the additional draw of the battery charger.

    I ran the AC yesterday off of the Honda 2200 with a AmWatt Appliance Load Tester attached. The outside temp was 98º and I was pulling exactly 15 amps with the fan on high. I was able to run the generator in ECO mode as well.

    I remind you that was running a 15K AC unit, an air conditioner with lesser BTU's will draw less.

    One additional benefit of the Easy Start this that is ramps up the fan/compressor so there is no loud bang of the compressor starting in the middle of the night anymore.....really nice.
  • It is Microair Easy Start.

  • I have one, installed in the parking lot of Horrible Freight. I have a 11k btu unit, with the honda 2000 it will start the AC in eco mode.
  • Yes, I have one on my AC and it works fantastic. Article on my web page about it. Www.rvbprecision.com
  • It wouldn't do it if the converter was charging much.
    In the past I have installed a heavy duty 20A light switch on the power feed for the converter so I can shut it down while the AC runs.
  • I installed a micro air on our 11.5 k unit. It brought the locked rotor amps way down. A 2000 watt generator is plenty of power to run the A/C. It’s the initial inrush current that is hard to overcome. The micro air or possibly a bigger hard start capacitor should let a 2000 watt generator work fine.
