This portable AC unit exceeded my expectations. It cools the room quickly, is easy to set up, and doesn’t take up much space at all. The controls are straightforward, and the noise level is surprisingly low—even on higher settings. It’s been a total lifesaver during hot days and makes the room comfortable within minutes. Great value for the price, and I’d absolutely recommend it to anyone looking for an effective, reliable portable AC.This

so unpackaging it was a pain in the butt because I was down a hand (injury). and I didn't realize until I was tearing into the box that I could've just lifted up on the box and then picked it up to take the styrofoam off the bottom. A little card of how to take it out of the packaging would be nice but... Setting it up was very easy I mean very very easy! The only thing that was difficult is the dang tube! what I found that worked is I only stretched the very end of it and kept the rest of it compressed and then held it with my legs and screwed it on it kept going on crooked so I resorted to desperate measures lol. once the tube is on though it's pretty sturdy. When you first turn it on it's pretty powerful! I mean the whole machine makes a jolt. and it will cool down a room that is around 83° weather down to 65° in 25 mins. you're able to angle the direction of flow too up down left and right. it claims to be very energy efficient per the yellow sticker, it says it only adds $77 annually. The rating on the website is a bit confusing because one thing says it has one star and then the other one says that the rating is 6.5. I had to resort to a small trashcan next to it to collect the condensation, I started with a water bottle but that filled up insanely quick! There's two options to let it fill up or two have it continuously drain into a bucket or container. I opted to put some type of container by it because the location where I have it is a little bit cramped. I don't really use the nighttime mode where it claims to be quieter, I can sleep through a tornado lol it does have a loud fan like noise and when it's working really hard you hear the compressor shutting on and off and it makes a loud jolt. I got the 8500 one for 300 ft.² my bedroom is around 120 Square (feet i think) paid around 202 usd. With memorial day holiday it got delayed two days but Amazon kept me updated where it was. Another complaint is the window panel piece, I first couldn't even figure it out how to attach it to the hose then I just gave up after I realized it wouldn't even fit in my window. so I resorted to cardboard and just folded it to make it have a seal. No issues with that but if it's raining heavy then I have to take it out. I wish that different sizes were sold instead of just being told well you can cut it in the directions. another thing if you really do not know what you're doing the directions are no help at all! Oh and one thing is I ran it without the tube just to see what would happen and it made my room insanely hot! The tube is definitely needed! And honestly I wish they put it on all dehumidifiers because the one that is in the living room does not have a tube and it makes the house hotter as it removes the moisture. There's three settings fan, Dehumidifier, and AC.

This thing works amazing, we placed it in a bedroom and it has a timer and keeps the room cold. The only flaw I found with it was the exhaust hose attaches very cheaply to the machine and we found a little bit of duck tape fixed our issue.

I love the airflow it provides. We have it in our bedroom, and even though the room isn't very large, it cools it down enough for us to sleep comfortably. The installation was fairly easy; you simply connect the hose to the window output and to the air conditioner. I also appreciate how portable it is, allowing us to move it to other rooms without the hassle of purchasing additional installation items.

Bought this AC for our son, who just moved into his first apartment. He has a room sized 9' by 10'. So the room is small. This AC works perfectly to cool down his small room. At first, he said it wasn't cooling. After reading the directions and making sure he was on the right settings, it is working great. He had a bit of trouble getting the panel with the hose installed in the window. He ended up wrapping a piece of cardboard with duct tape as a shim to bring the panel up to the window level. He also taped around the edges to keep bugs out! He is using a gallon water bottle to collect the water that the AC takes out of the hot air. That makes it easy to empty the water when the bottle fills up. Very pleased with this purchase. The AC is nice and small, looks good, and does the job. I would definitely recommend this product.

Works excellent so far, cools my small bedroom during heatwave with no issues. Got tired of the window rattlers, so went portable. I always hated the window AC's that block up the whole window and are loud. And also doesn't allow my dog look outside. So I bought some portable AC's this year. This one works great in my small bedroom. Runs efficient and not overly loud. On high fan it's definitely not quiet, but not as loud as a small window ac. I also have grow tents so need the fresh/dry/cool room whenever possible. Note that on fan mode it still blows air out the ducting, which means it has dual fans inside, which is a good thing. I highly recommend buying a automatic condenser pump (as pictured) when using any portable AC's so there is no worrying about the tank filling up and the AC shutting off. I've only used this AC for a few weeks, so can't attest to it's true lifespan. I know portable AC's, can fail more often then window ac's, leaving you are stuck with a 50+ lbs item you are burdened to ship back. At this price it's a good deal. If I get 2-3 summers out of it then I will feel I got what a paid for. I may edit this review as time goes on. UPDATE: 100 degree Heat wave hits New England. Got this little AC running 24/7, right now its 98 degrees outside with 99% humidity, and about 80 degrees 65% humidity inside the bedroom. I think that's the limit. Looking back I should have grabbed the higher btu unit for days like today. But it is what it is. Definitely get yourself an insulted duct sleeve (as pictured) or make one with a sheet. That will help the heat get out the window. I will add new pics. Recap of tips, and must haves, for portable AC's users.. -Buy an automatic condenser pump when you buy any portable AC and never worry about a full tank/bucket. -Buy a exhaust insulator sleeve or make your own with a sheet/blanket. -Constantly check/clean the filters. Clean weekly if using 24/7. -Make sure to seal all the leaks around your window so the AC pulls the rooms hot air and not outside hot air.

We purchased two of these portable air conditioners for our teenagers’ third-story bedrooms, and they have been fantastic. Those rooms tend to get extremely hot in the summer, but these units cool them down quickly and keep the temperature comfortable all night long. They were easy to set up, fit well in their space, can be moved around and run quietly enough that they don’t interfere with sleep. We’ve been especially impressed with how consistently they maintain the set temperature, even during the hottest days. If you have upstairs bedrooms that struggle to stay cool, I highly recommend this unit. It’s been a game changer for us!
