This Euhomy Is the Smallest Portable A/C I've Tested, and It Made Quick Work of Cooling My Bedroom

5 min readMany portable air conditioners fall into one of two camps: compact units that struggle to cool small bedrooms or powerful units that take up way too much space. When I saw this Euhomy 10,000 BTU portable air conditioner, I was curious whether it could split the difference. My bedroom window is a tall sliding pane that's given other units trouble, and I needed something that could handle the awkward window and the space itself without dominating the room.While portable air conditioners aren’t as powerful or efficient as window air conditioners or ductless air conditioners, they’re a great fit for renters and homeowners who want a more mobile option. It turns out the Euhomy is the smallest portable A/C I’ve tested, and it still cools up to 450 square feet. That combination isn’t easy to find, and it’s what got me interested in the first place.ProsCompact footprint, big coverageToggle-latch window panelsFast, quiet cooling in sleep modeGRS-certified recycled materialsConsNo inverter, so it cycles on and off Manual louvers onlyKey SpecsCooling Capacity10,000 BTU (ASHRAE)CoverageUp to 450 square feetNoise LevelAround 50 dBModesCool, fan, dehumidify, sleepDimensions11.4"D x 12"W x 26.7"HWeightApprox 45 lbHow I TestedI set this A/C up in my bedroom, which gets some of the hottest afternoon sun in my house, and ran it through the hottest stretch of the summer so far. I evaluated it for cooling speed, assembly, window fit, noise at different settings, and how easy the unit was to move around.Lauren BongardThe Euhomy Portable A/C comes with a remote that works up to a few feet away.Small Footprint, Big PerformanceThis unit’s dimensions are just 11.4 inches deep, 12 inches wide, and 26.7 inches tall, which makes it the smallest portable A/C I’ve tested. I expected that diminutive size to come with a trade-off in cooling power, and while it didn’t eat up much floor space, it got my room cold fast on the hottest days. This portable A/C cools spaces up to 450 square feet—far more than my room needed—and it had the perfect footprint for my bedroom.The Window Kit Was the Easiest I’ve Ever InstalledAs small as the unit is, the four-piece window extension panel for the hose isn’t small—which ended up working in my favor. My bedroom window has a sliding pane that’s 52 inches tall, and this was the only air conditioner hose extension panel I’ve tested that came close to fitting (I only needed to plug the top few inches of the opening for an airtight fit). The unit also came with a handy foam seal strip to fill gaps and block outdoor air, so I didn’t need to buy any.Lauren BongardI was able to get an airtight fit with the Euhomy.Plus, the panel set was the easiest I’ve adjusted on any portable A/C so far. The lengths let you choose how many and which panels you need for your windows (one to four, depending on the width or height of your window). And instead of wing nut screws that are frustrating to twist while trying to hold the panels in place, Euhomy uses toggle latches that clip the pieces together securely at whatever length matches your window opening. Just slide the panels together, open the clip, adjust the panels to the length you need, and pinch the toggle latch closed to secure.Setup Took Just a Few MinutesAssembly was simple. Twist the hose into the air vent connector (which has arrows to tell you which way to turn), attach the flat nozzle, plug it in, and press start. The remote and the panel display are both easy to navigate, so I wasn’t digging through a manual to figure out basic settings.The unit ships with all the weatherstripping I needed for a tight seal, plus a hose for the dehumidifier setting if you need it. I live in a low-humidity area, so I didn’t end up using that function, but I like that it’s included for anyone who does. In cooling and fan modes, the unit doesn’t require any drainage at all.Sleep Mode Lives Up to Its NameSleep mode is quiet, and the display lights shut off completely, so there’s no ambient glow keeping me up. That’s become one of my favorite features for bedroom units, since I don’t want a nightlight I didn’t ask for.A Few Places It Falls ShortThe biggest downside to this portable air conditioner is that it lacks an inverter, so it cycles on and off between cooling instead of running continuously. While that didn’t bother me, it could be distracting for light sleepers or sound-sensitive individuals.Some competing units have self-adjusting or oscillating louvers, but this one is manual only. You can angle the airflow down toward the floor, up toward the ceiling, or anywhere in between, but the louvers won’t swing left or right or on their own.Since it’s a single-hose design, it can pull warm air back into the room. I haven’t noticed that issue in my bedroom, since the rest of my house helps equalize the pressure, but it’s a bigger factor for larger, more open spaces. If that is a concern for you, you might want to consider a dual-hose portable A/C instead.Mobility is another mixed bag. It was a little tough to wheel across carpeting, and I ended up pushing it with my knees more than once while getting it into place, even with the carry handles helping. The smaller, lighter size does make it easier to manage than a bulkier model, but don’t expect it to glide across carpet the way it does on hardwood. That said, it’s likely only an issue if you plan to move it from room to room frequently.No App, but I Didn't Miss ItThis model doesn’t have WiFi or app controls, but I didn’t mind that at all. I was able to turn it on manually before I needed it, which worked fine for a bedroom unit I use on a predictable schedule. That’s different from the WiFi-enabled model I use in my living room, where I like being able to turn the A/C on remotely so I’m not walking into a warm room after being out.If app control matters to you, you may want to go with a WiFi-enabled portable air conditioner. But skipping the app is a plus if you’d rather not add one more thing to your phone.Lauren BongardInstalling the exhaust pipe only took a few minutes.Small Details That Add UpThe unit’s flat top is a nice touch I wasn’t expecting. I could see using it as a nightstand in a small bedroom, or as a spot for a potted plant or clock in an office. Between the fan and dehumidify modes, this air conditioner is also useful outside of peak cooling season, and the small footprint and rectangular profile make it easy to incorporate into a room’s layout without feeling like you’re sleeping or working in an appliance store.I also like that this unit carries Global Recycled Standard certification, a third-party verification confirming it contains at least 50 percent recycled materials, uses safer chemicals, and holds manufacturers to worker well-being standards. That doesn’t affect day-to-day performance, but I appreciate knowing it’s built in.Final ThoughtsThe Euhomy 10,000 BTU portable air conditioner is one of the easiest portable A/Cs I’ve set up, and the coverage-to-footprint ratio is hard to beat. The toggle-latch window panels alone make it worth considering if you’ve fought with wing nut screws on other units, and sleep mode delivers what it promises.It’s not the right pick if you want oscillating louvers, an inverter for quieter cycling, or app control. But if you have a smaller room that needs a smaller-sized air conditioner, a tricky window, or if you don’t need smart features, this unit checks the boxes that matter most.Shop the Euhomy 10,000 BTU Portable Air ConditionerMore Portable A/Cs We LoveLG Portable Air ConditionerDreo AC515S Portable Air ConditionerNow 15% OffWhynter ARC-14S Portable Air ConditionerLauren Bongard is a full-time freelance writer focusing on home improvement, lifestyle, and reviews.
