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.

With all that said if you're trying to cool down a single room upstairs that runs hotter a single hose will work fine and still be cheaper than running your central air lower to cool one room colder.

You can read the installation manual here and see if it will work for you. https://www.hisense-usa.com/suppo...gd-hisense

There's one 25" piece for the dual hose two 18" filler panels and one 9.5" panel.
Interesting the manual says windows up to 50" but 25+18+18 = 61inch
25+18+18+9.5 = 70.5"
I have ~ 58 horizontal-opening window. I don't see why I can't use all the supplied panels…
Will it be more efficient than a baseboard heater?

^ Considering the current price of both portable ACs, I guess the Hisense is good enough. But if you can get the LG one for sale again, it'll definitely cool a lot better, at least from my experience.
If you have one room you're attempting to cool and don't mind other rooms heating up more, then sure a single hose will do. Otherwise do yourself and your energy bill a favor and get a dual hose or a window unit.
If you don't believe me try to cool a small shed with a single hose portable AC in it. You'll find that very quickly after turning on the AC the room will quickly reach the temperature of the outside air and will only feel cool where the air is blowing from the AC, the room itself will never cool down.
