Why are single hosed portable air conditioners not a good option to buy when it comes to cooling?

I typically hear that if you want to buy an air conditioner for a particular room, it is better to use a window air conditioner or if that is not an option then use a dual hosed portable air conditioner. What is the difference between single hosed and dual hosed portable ac units? Do dual hosed units cool better and quicker?

    all the hot air that a single hose puts outside WAS cool air that's been heated.  AND the amount of hot air that's being pushed out is replaced with hot air from outside the house.  (EVERY house has air leaks around doors, windows, power outlets, and sill plates behind your wall baseboards.)

    dual hose units pull outside air to run across the condenser coil then exhaust it from the other hose.  Single hose pulls conditioned air from room across coil an exhausts it.

    The thing is with the singe hose unit, it uses room air to cool of the condenser coil, which wastes cold room air. I'll be honest, it's really not that big of an issue. If you can afford a dual hose unit, do so, as they're even more efficient than window units.

    The most efficient option to heat/cool a single room is a mini split system with a wall mounted blower and a separate compressor unit outside, however they are not cheap, often costing over £300

    The  single  hosed  ones  blow out inside  air to  get rid of the heat.

    Dual  hosed ones   pull outside  air and use that to  get rid of the heat.

    The  single  hosed ones    blow some of the  cooled  air  outside and have to  replace that  air  with  hot  air  from outside.

    It isn't an issue of single or double hosed.

    ALL portable air conditioners are less efficient than window units because they vent through a hose instead of directly outside.

      While the portability aspect is true, it is much less of a factor than the single hose sucking air out of the room thus forcing exterior air infiltration.

      Alec (the guy who writes and makes these videos) does excellent and thorough research.  This one about portable air conditioners covers the disadvantages very well.
