I don't even know how they get away with marketing that feature, it's basically a full on lie. Maybe they only market it like that on US customer portals since in the US lying to the public is not only permitted but encouraged.
Not the same thing, but the Ecoflow naming is terrible inviting confusion.

This delta 2 claims it can do 1800 watts with no mention of X-Boost. Don't have it myself so I can't confirm.
I have a 1500Wh/2000W from another brand now that I've even ran an 8000 BTU airconditioner from, cold start and all. So my issues could've easily been unrelated.

Pecron E600LFP has 1200W inverter, $227 after GOGREEN code.

X-Boost and the similar technologies every manufacturer offers are techniques to operate certain devices that require a fixed amount of amps. Heating devices are most common, ie an electric skillet, heat gun, hair dryer, space heater. These devices will work but at a reduced output, ie you're only getting 800 watts worth of heat out of the River 2 Pro (& frequently less).
The other way to think about these techniques is that they can sort of function like a soft-start - the inverter can briefly supply higher amperage at a lower voltage, then when the amperage draw is reduced the voltage will return to normal.
You're much better off using a power station with a sufficiently strong inverter if you know the application in advance, but in a pinch these techniques can be the difference between a device working poorly or not at all.
