I bought one. At this price, it's hard for me to pass. I'll use it to supplement AC power in my bedroom so I'm not cooling a whole house for just my room.
Also, it's great for if I lose power from a hurricane. My generator can run this easily.
Portable ACs are inherently inefficient, even dual-hose models. Throwing an inverter in one is like putting a 97% efficient furnace in a house with single pane glass and no insulation -- if the fundamentals are bad, some fancy tech isn't going to fix the problem. The compressor is inside the conditioned space, the exhaust tubes are not insulated, the fans have difficulty pushing adequate airflow through the tubes, and to add salt into the wound, single-hose units pull in conditioned air from inside the envelope of the building and exhaust it outside after using it to cool the condenser (which causes the building to suck hot outside air).

I would agree and disagree.
On one hand, you are not making things worse by adding (even more) gross inefficiency on top of a bad situation. But on the other hand (and more real world) you are not likely to use one of these portable AC's (efficient or otherwise) enough to ever notice, or perhaps even recoup over a decade, the extra costs associated with with investing in a higher end model unless you just want the features. And if you did use the AC that much, you are better off investing in permanent HVAC solution (for example a small mini split) or buying a cheapo unit and using the difference in chalking, weather stripping, curtains, that will help you 24/7/365...regardless if the single house non-inverter unit is running or not. That likely will have a much greater bang for your buck ROI.
I was once at a RV dealership, another customer was debating buying a $70K motorhome or a $130K motorhome, their deciding factor was MPG. The salesman even told them they could drive the better MPG unit every hour of every day for the rest of their lives and they would never make back the different of the extra $60,000 in gas $. Of course they bought the $60K more unit to "save" 10 MPG on something they probably drive 2000 miles per year

Portable AC is mostly for conveience and small room or special case like a mobile home, where a window AC is not possible or too costly.
Never understood the logic of the dual hose design, where the hot air exhuaut is right next to the fresh air intake, isn't the hot air goes right back to the AC? while we debate how inefficient of the exhaut pipe alone, this design kills all efficiency.
Also there is exhaut pipe cover sold on amazon for $20 specifically made for portal AC, that should help.
The reason inverter is good as it doesn't push the wattage to its maximum whenever turning on, rather it consume electric as needed for compressing the air. It felt comfortable and supposedly costs less but might be negligent anyway.

If someone's going to be anal about that, there are some DIY solutions to help like extending the intake (or exhaust) hose to prevent what you're saying.
The biggest benefit would be not getting negative pressure since it sucks outside air to cool and spits the hot air outside as well. The only air intake inside also gets pushed inside (after air is cooled).

Without dual hoses, all of the air exhausted by portable ACs is conditioned air from inside the envelope of the building, which will be replaced via infiltration by hot air from outside ... which then needs to be cooled. Having to cool all of that replacement air from scratch far outweighs the downside of maybe picking up a little of the exhaust air in the intake.
This is one of the reasons why the SACC BTU number for single hose units is so much lower than the ASHRAE -- ASHRAE doesn't consider infiltration air. In the case of this unit, nearly 30% of the cooling output is wasted due to poor (uninsulated single hose) design.
