That link says what the X does somewhat. The regular 90's specs are given there too, but are not very clear. That 2200 is more of a gen than the 2000 for sure, and it must also do more than its rating.
DLS 90 specs say 21.8a x 108v so that's 2354w but no mention of the 0.7 PF it has. Of course the Honda will be more like 123v doing the 90, which muddifies things. How can the 2200 do 21.8 amps?? Same power 2354/123v = 19 amps. 2200/120 = 18 amps, 1800/120 = 15 amps
EDIT--2200 has receptacles marked 15A but have the slot to take 20A plug. (I haven't read the manual where it probably explains that)
Output of the 90 is 1200w it says, but at 14.6v DC (battery voltage) that would be 1200/14.6 = 82 amps
Doing it backwards, output at 90 amps with battery at 14.6v = 1314w.
85% efficiency makes input 1546w, PF 0.7 makes that 2208VA, so the 2200 gen at 123v would be at 17.9 amps.
As usual with the converter specs you see, they don't help much. They normally understate the input requirement for the generator to supply by not mentioning VA and PF, but just the "watts" as though PF were 1.0
You do need a 20A circuit to run that 90 amper with its 0.7 PF. Same with the PD 80 amper. The PowerMax 100 amper (but not the 75 amper despite some ads that say it does) has PF-correction so it can have its 15a plug, but it is borderline for a 20A plug depending on if it will be continually run or just temporary by some NEC rule it seems. ISTR you can order it with whichever plug you want.
Newer USA RVs have all 20a branch circuits with 12AWG wire so at least you are good there. Older RVs with 15a branches not so much.
Note the new IQ4s you can get now with different charging profiles to suit your battery type. (like yours for the AGMs) There is also a special IQ4-X for the X models.
