Mobile air conditioning for campers, caravans and co

How are your experiences with mobile air conditioners? Yesterday I got an advertising email from Ecoflow, which now sells not only powerstations, but also a compressor air conditioner with battery operation: Here’s a test:https://www.techstage.de/…/2g42h5s and here’s the device:https://www.ecoflow.com/en/wave-2-portable-air-conditioner So far I only know the small split devices, where you hang the external part in front of windows, for example the Euro AC 2400. not self-sufficient with battery. Or the evaporation air conditioners, which only work in dry heat. Or devices for fixed installation with 12V/24V For the Ecoflow you would have to drill a hole in wall, floor or ceiling, or pierce a window to get rid of the warm exhaust air. In the caravan you might also be able to put the device in the storage compartment, next to the gas bottles. At least a large additional battery is useful if you want to stand self-sufficiently, optimally natural at 540W power consumption I put PV on the roof.
