AC works by using a powered heat exchanger that cools indoor air at the expense of heating outdoor air. It's really inefficient to do by any method, but it's all we have.
With both types indoor air is recirculated and cooled on the cold side of the heat exchanger from your room back into your room, while air is drawn onto the hot side of the heat exchanger making heating the air and then it sends this hot air outdoors. Heating the outdoors to cool your indoors.
Where things differ with hoses is the source of the cool air...
With a single hose the hose is used only to send hot air outdoors. This means the unit pulls cold air from in your room to cool the heat exchanger. This air is pulled from the cool indoor air you have used electricity & paid to cool which is vented outside. That cool air sucked out of the room is replenished with uncooled air from the surroundings of the room - either from outdoors or warmer parts of the house, whichever leaks more. This means a portion of your cooled air is perpetually being "wasted" and sucked out of the room.
Dual hose systems use one hose as an inlet to pull outdoor air into the hot side of the AC to cool the heat exchanger. Cooled indoor air is recirculated across the cool side of the heat exchanger, cooling it further. The outdoor air that is drawn across the hot side is sent back outdoors by the second hose of the system, extra hot.
Dual hose systems are about 30% more efficient than single hose. Which means an 8k BTU dual hose is more effecient than a 10k single hose.
Frankly, though, all portables are trash compared to even a window unit. My experience is single hose portable ACs provide less than half the cooling of a window unit of the same BTU.
Only when it's absolutely impossible to install a window AC should a portable be considered.
I'm not really sure why I spent so much time to write all of this out now that I'm finished ... besides inertia of needing to finish.

In my opinion, it is better to get an inverter portable air conditioner or just the window unit.

The hoses are only 60". I had a really difficult time getting this to work with my casement windows (mounted vertically rather than horizontally). The top-most hose was just simply too far from the ground. I had to buy an extension on Amazon to extend one hose.

The cutout for the secondary drain hose is in the same compartment as where the inlet hose is attached. So as the outside air is pulled into the ac unit, some will escape through the cutout and enter the home. shining a light into the inlet port and you will see light coming out of the cutout. Also the seams of the housing don't appear to be air tight.
Just want to mention this for those who are concerned about outside air intrusion.
Re-read your comment. My bad.
