I have the Yamaha EF2400iS. It's the predecessor to the EF2400iSHC. The new model has an even higher starting capacity than the 2400iS.
That said, there's very little I can't run with mine. When it was introduced, it was designed to do what a single Honda 2KW cannot. It will reliably start, run, and restart a roof top A/C unit with a high head pressure.
I'm one of those who has successfully been able to repeatedly start a variety of 13,500 BTU A/C units, each equipped with a Supco SPP6 hard start capacitor, with the 2 different Honda EU2000i gensets that I've owned. The catch was that I'm only at ~ 250' above sea level and if temps rose beyond ~ 85F then the genset finally did reach the limits of it's ability to start these A/C units. No question about it, Yamaha's EF2400iS and it's improved EF2400iSHC both filled a gap that Honda never addressed - until now, with the recent introduction of Honda's new EU2200i which is MUCH smaller and lighter than an EF2400iSHC. If I were buying another genset so I could power an RV A/C, recharge the trailer batteries, and as back up power for the house I'd this time around invest in a new EU2200i and spend the extra $$$ not spent on the more costly EF2400iSHC instead on equipping the A/C with a MicroAir Easy Start Soft Starter Kit, the combination of which have been proven to work quite well for this task even when elevation increases and ambient temps are quite high.
