Question: Does it have to be placed near a window
Document: A case of wishful thinking perhaps?I would also add that when considering the "installation" of one of these portable units, check your window first. Sliding windows only open one way (either right to left or vice verse) and this opening side is where you exhaust hose will have to be placed. You won't have the option of going to either side.
And even in very high humidity situations, the unit does not shut off and evaporates the water very well.Ultimately, I bought an 8000 btu window unit and this cools the bedroom very nicely. I placed this unit in my daughter's bedroom and she has it facing her bed and it works for her when she sleeps. But it DOES NOT cool the rest of the room  at all. Her room is 11 x 15. But I don't think a larger BTU unit would matter.
So in my bedroom, I placed it a few feet from the bed and had it blowing in the bed's direction, and it was comfortable. But walk to a different area of the room, and it was much warmer. So this can probably cool a closet, but not much else. Sorry, I did not want to believe it, but now that I own one that is the sorry case. It's not that noisy, but really does little.
The unit came damaged the first time delivered. Amazon did an amazing job by having the unit picked up the next day. The replacement was perfect. The reason I chose portable was due to the windows I have to work with. It was capable of reducing the temperature by 10  and lowering the humidity. The drain for the condensation is at the lowest point of the unit which makes it a pain to drain. I placed it on a chair to drain into a bucket.
I bought this to use in my pop-up camper, which is a small model that isn't braced for a roof AC unit (8ft box).This is a large unit, but I'm using it on a counter near the door and run the exhaust to the screen on a bunk, and zip around it.It actually does cool the camper! In 100 degree heat it can't really keep up, but it makes a difference.
I attempted to use this in my master bedroom and it couldn't cool it down. I sealed the exhaust tube to the window and ran it for several hours.
I will never buy another traditional window-mounted air conditioner after using a portable air conditioner. But I do advise buyers to be sure they buy a unit that is powerful enough to meet their expectations.
Both brands have remotes and are programmable, have castor wheels, have easy-install window vents and hoses, and have 3 functions (fan, cooling, and dehumidifier). The Pinguino has a very sensitive thermostat, making it easy to adjust one or two degrees.
These units are far, far easier and safer to install and store during cooler months than traditional window mounted units, and they will not damage windowsills or window frames. They work in windows that slide open to the side as well as typical windows.
The unit does not cool the room, the 5000 btu window unit that this portable replaced was more effective at cooling my small room. Another drawback  is the loovers that direct the airflow only allow for side to side adjustment,but not for up and down. Buying this was a big mistake.
Answer: To utilize the included vent kit, it would need to placed within four feet or so of a window. Even if you are going to rig up your own ventilation system, it still requires the ability to vent into a space that is not being conditioned/dehumidified.
