8000/10000 BTU Portable Air Conditioner 3-in-1 with LED Display and Remote Control AC5421

Seems to be running as expected and advertised. The only negative is eliminating the condensate. We do not have a floor drain where the unit is being used and there is no easy way to empty the condensate. A removable tray would be a great improvement. The drain is positioned so low on the unit that even the smallest tray will not fit under it. I have been using the drain hose to empty onto a bath towel and changing the towel when it becomes saturated. Not ideal by any means.

The orders were received quickly. I bought 2 of the units . They have been working very well keeping the area cool and comfortable. The price is very fair. I recommend this product.

My roommate just got me this for my bedroom since he's always cold and I'm always hot. Last night was my first night sleeping with it on and let me tell you... the difference it made is unbelievable! I am of a particular age so I stay in constant hot flash mode. This is a game changer! Now he can have the house temp at 76° and I won't feel like I'm going to fall out when cleaning or sleeping 🥰

I have been really impressed with the Kissair brand. Their small appliances have been consistently heavy, well made, and easy to use. I would not be surprised if they are made in the same facility as major name brands! This portable AC will do a great job of cooling a large room or apt provided you set it up as directed. I've included a photo of how it's packaged - that flexible hose on top needs to be vented so that it can pull outside air. I also like that this one has a built in dehumidifier so that if you live in a humid climate, it doesn't pull that humidity in and spit it out in your house. :)

This air conditioner has been AMAZING!! My 9 year new upstairs HVAC is down currently. It has multiple leaks in the outdoor unit and with the change end of 2025 in R- whatever number… my part needed is on back order for 101 days.

I saw historically two days after finding this out! It has been such a wonderful unit. Didn’t take hardly any time to get setup in the window and plugged in and turned on.

Doing a great job cooling off the master bedroom and even part of the hallway. We have a similar unit that’s older from a family member that is in kids room, these two have helped cool the entire upstairs while we wait in the south for a part to come in sometime in June…

So this is getting a great test run! So far so great and love that it comes with a remote. I didn’t think I’d use that initially but ya I have! In the middle of the night when needing to adjust is a great option. Also love that you can turn off the lights on the display so you don’t see those while trying to sleep.

So many settings and it works like a charm. This is great if you need to cool a large room in a scenario like mine or if you don’t have central air. One of these in each room would cool an entire floor no issue.

Granted, we have not had any very hot days, but I have tried this on an 83° day and here is what I’ve noticed so far……

It blows out cold air as expected, but it does seem to blow it out quite hard which I love. It cooled the room off in a 250 ft.² cabin, but would it do 350 ft.² like it claims it would when it is 95° out? That I don’t know, and from what I’m seeing I don’t think it would handle that much, but I cannot be for sure. I just feel that size square footage when it’s 90+ degrees would be difficult for this portable AC but that’s just my opinion.

I will say as far as an office goes or a dorm, or a bedroom in a house I think this would be a rock solid. The company Kissair is the company that I have a few other products from, and so far their products have been awesome so I do wanna make sure and point out that this is a great deal for the price and for 250 ft.² maybe a little more I would feel quite confident this would do the trick. I just cannot answer something larger than that.

With that in mind this is very durable, I love the way the wheels move and glide quite freely and I do believe this is a good bang for your buck.

works beautifully. I’m very happy. I got it.

It’s been great and cooled off our den quickly.

This is a very nice portable A/C unit!

We love it but it has not been to hot here yet to really know

This has truly helped with my NYC apartment. Thank you so much!!!

Living in Oregon, one would think AC is not needed, but when you live on the second floor and summer hits, the humidity, the heat and the sun really does make it miserable.This Kissair AC unit has made all the difference in our bedroom keeping us cool at night and has a dehumidifier to help keep the humidity at a level that keeps my hair from going frizzy. Such a powerful unit with the quietest noise. Yes you can still hear it like a normal conversation. I like that it doesn’t scream at me when it’s in. Absolutely recommend this piece if you want to stay cool in the summer.

Genial

Great item

Perfect!!!

Unit as described. Works great.

We are using this portable air conditioner in our home office. The AC was very easy to install in just a few minutes. It came with the window hose kit to install it with. The remote is handy and it also has controls built into the top. Even with the PC and other equipment running, it keeps the office cool. It would be perfect for any smaller type room.

Perfect for the shed. Helps keep the shed cooler and is a good way lower the temperature. Perfect for the space I have. Easy to use and assemble. Great air flow.

This portable ac unit arrives safely packaged and in perfect condition. It's easy to pull out of the box and the setup is super simple. It comes with the window vent system that is easy to slide into the window and secure to the unit. Once vented you just turn it on and it's good to go. The wheels make it easy to move around and the remote allows you to adjust the mode, temp and timer from anywhere in the room. It does a good job of holding the set temperature. It's not super loud compared to my old portable unit. Overall it's a great price for a good quality unit.

This 8,000 BTU portable AC is a solid unit—well-built and definitely feels substantial when unboxed. The compressor cools my space quickly, and it's surprisingly efficient for small to medium rooms up to about 350 sq.ft. The 3-in-1 functions (cool, dehumidify, fan) are handy, and the adjustable temperature range of 62°F–86°F lets me set it just right.
It's heavy out of the box, but the built-in swivel casters and handles make it easy to move around once it's set up. Installation was straightforward with the included window kit, and cleaning the mesh filter is simple. Quiet enough to run during sleep, and the remote and LED panel are intuitive. Overall, it's a dependable, high-quality portable AC that really delivers.

This AC unit has really impressed me. It was very easy to install in my small office window, and I noticed a temperature change within about 15 minutes of turning it on.
It doesn't take up much space, which I love, and it's not overly noticeable in the window. It's already done a great job cooling the room, and I think it'll be perfect for keeping the space comfortable during the hotter summer months. So far I an happy with the performance.

Powerful and Efficient 8,000 BTU AC—Perfect for Large Spaces and Outbuildings
I purchased this AC unit to add cooling to my outdoor building, and it has worked exactly as needed. Setup was very simple, and it started cooling the entire shed quickly after installation.
The 8,000 BTU output is strong and effective, and the unit is easy to move if needed. It cooled the space in about an hour and maintained a comfortable temperature well.
Energy use did increase slightly, but not significantly considering the performance. Overall, this is a great option for larger rooms, sheds, or outdoor buildings where strong, reliable cooling is needed.

​This 8,000 BTU portable air conditioner has been a fantastic addition to my space, providing consistent and powerful cooling during the recent heatwaves. The setup was incredibly straightforward with the included window kit, and the 360° casters make it effortless to move between the office and the bedroom depending on where I’m working. The LED display and remote control are very user-friendly, allowing for quick adjustments to the fan speed or sleep mode without any hassle. It runs surprisingly quiet, which is a huge plus when I need to focus or get a good night's rest.
​The absolute best feature of this unit, however, is the self-evaporating system. Unlike other portable ACs I have used in the past, this one does not require constant monitoring or frequent trips to the sink. The water doesn't build up to the point where I have to manually dump a heavy tank, and I haven't had to worry about draining it at all. This level of convenience makes it a truly low-maintenance solution for keeping a room comfortable. It is a reliable, high-quality cooling unit that delivers exactly what it promises.

Our ac went out and I need acs to set in my rooms to keep my house cool.
I saw this and figured that I would try it. I liked that it was also a dehumidifier.
It was easy to set up. It has a large LED screen that is easy to read and easy to set. It gets really cold and the dehumifier works great.
I am so glad I got this. It issits perfectly in the corner and it cools off my room. The higher the fan speed the more I hear it, but if I am watching a show I don't hear it.

A true freeze machine. It can create a cold indoor tundra in one room then glide it along its quick action wheels and turn the next room in a frozen wonderland. Its ultra cold like the quality of a commercial unit and even more practical than a window unit. I love this machine. My only advice would be to make sure you keep up to date with the water and the exhaust. The exhaust needs to connect to the machine and can sometimes get loose if moved a lot and used often. It is really a simple upkeep and a tightening of a clamp. The air flow is healthy and a great addition to any home. Its easy to use and a money saver because you dont need a bunch of units. You can just move this one to the room your in the most.
