If you’re dreading the summer months because you want an air conditioner but don’t have much space to put it in, then it might be time for you to check out our guide to the smallest portable air conditioners of 2019! Also, check out the best RV air conditioner and our roundup of the leading portable air conditioners for an RV. For this list showcasing the Best Portable ACs on the market, we wanted to consider AC units and air conditioners that truly live up to their “portable” name, measuring no more than 30 inches tall, 18 inches across, and 15 inches deep.
We also ruled out any air conditioners that were less than 10,000 BTUs, because just because you’re trying to save some room in your house by opting for a portable AC doesn’t mean you have to sacrifice on cooling power to get it!
With all these factors in mind, we had no problem naming the Honeywell MN10CESWW ($337) the smallest portable air conditioner thanks to its solid 10,000 BTU rating, 70 pint/per 24-hr dehumidification engine, and minimal frame that only measures 28-inches tall at its highest point. Read on to learn more about these units, and don’t forget to check out the most popular air conditioners.
Award: Editor’s Choice/Best All-Around Small Air Conditioner
Price: $337.58 | Features: 10,000 BTUs, 70 pint dehumidification/24hrs, LCD display
WHY IT’S A TOP PICK: For an all-around solid choice at a great price, the Honeywell MN10CESWW takes the cake.
If the Honeywell portable air conditioner sounds a bit familiar to you, you might recognize it from our original best portable A/C list of 2019. We already lauded the machine for its no-drip evaporation system as well as its super simple setup process, but what makes it the #1 pick for this list is its downright petite profile compared to other air conditioners with the same amount of power output.

All told the Honeywell MN10CESWW tops out at a mere 28 inches tall, 15.2 inches deep, and 18.1 inches across. It’s not the tallest, greatest tower air conditioner out there, but it does what it’s designed to do. Potential buyers should keep in mind that because it has the larger motor to push out 10,000 BTUs, the unit itself is actually quite heavy at just over 61lbs. This is hefty for even larger A/C units, but thankfully the MC10CESWW comes with its own set of caster wheels on the bottom so you can easily roll it from one room to the next without breaking your back to get it there!

The Whynter isn’t the sleekest looking option, but it’s got more than enough power to make up for it
Award: Best Budget Small Air Conditioner
Price: $265.99 || Features: 10,000 BTUs, single-hose setup, included remote and programmable LCD display
WHY IT’S A TOP PICK: The Whynter ARC-10WB packs a lot of punch in a pint-sized package.
While the Honeywell is the best pick for both size and portability, the Whynter ARC-10WB definitely takes the cake when it comes to price. At just $265.99 (during the time of this writing), the Whynter is a cheap small portable air conditioner that still provides 10,000 BTUs of room-chilling bliss during the sweltering summer months.

Unlike the Ontel portable air conditioner, which is super tiny, this Whynter portable air conditioner measures just 28 inches at the tallest point, with 17 inches of width and 13.6 inches of depth. This makes it smaller, but it’s also heavier than the Honeywell at 64lbs thanks to its denser, more compact size. Other notable features include the antibacterial ion filter which removes pollutants and germs from the air while you’re cooling down your room, as well as a self-evaporating de-humidifier that makes sure you don’t have to spend your precious vacation days emptying trays of still water every six hours.
If you’re on a budget but still want the smallest portable A/C that will get the job done with minimal effort on your part, you can’t go wrong with the Whynter ARC-10WB.
Award: Lightest Small Portable Air Conditioner
Price: $298.00 | Features: 10,000 BTU, ultra-efficient operation, auto-evaporation system
WHY IT’S A TOP PICK: The Haier HPB10XCR is the pick for you if portability is the most important feature you’re on the hunt for.
Last up we come to a model with a brand name that may not be as immediately recognizable to most consumers, but still has the power and portability to back itself up. Heck, it wouldn’t make it onto our best of 2019 list unless it did, right?
The Haier HPB10XCR is far and away from both the smallest and lightest portable A/C here, without question. At only 27.5 inches tall at a feather-light 41 pounds (by comparison to the other choices on this list, at least), if you’re only in the market for the smallest and most portable option, you’re going to want to go with the Haier over anything else. This isn’t the top mini split obviously, but it’s suitable for those that need something small, portable, and manageable.
The Haier comes with a 10,000 BTU rating just like the rest, alongside a single-hose system that can cool, fan, or even de-humidify the surrounding environment for up to 24-hours on a one-timer. While its stats are standard, its small stature and lightweight build are what really set it apart from the pack. However, if you need a regular-sized unit, read about the best air conditioners to learn more.

Power Saving Options
Maybe Get a Window Unit Instead: While all these units are convenient for their portability, ultimately if the size is your main concern, a window-based model can’t be beaten. With window-based A/C, not only is the unit itself significantly smaller and lighter than portable units, half the housing will always sit outside your house to dispose of wastewater and siphon in new air.
Go Big if You’ve Got a Big Home: Although it might be tempting to keep things as tight and neat as possible, these portable A/C units are best for smaller, cramped rooms only. If you’re trying to cool an entire bottom floor or dining room/living room combo with a 10,000 BTU unit, prepare to be sorely underwhelmed since these units are only rated to chill a maximum of 350 sq. ft at a time.
Now that you know which units out there made the cut for our smallest portable air conditioners and that the Honeywell MN10CESWW takes the cake as #1, what other types are out there that are still worth a mention?
Well, being that it’s 2019, of course, there are plenty of smart home-ready Wi-Fi-enabled air conditioners you can take a look at that makes it easy to control your home cooling system from wherever you are out in the world.
Or, if you just want a plain old powerful monster of a portable A/C that can easily cool rooms 500 sq. ft or larger, check out our review of the 14,000 BTU LG LP1415WXRSM (which also has its own Wi-Fi features to boot!). Keep in mind that if you get a monster A/C, it’s going to be loud, so consider a quiet portable A/C before you make a choice.
Find out whether your portable AC comes with a remote control for easy operation. Plus, you might want to have a look at dual hose options as well. For larger rooms, a dual hose AC unit is a better choice since they eliminate the negative air pressure problem, but they do cost a bit more. Yet, you’ll get great cooling with a high-end dual hose portable air conditioner.
Another popular model worth looking at is the Black Decker Portable 12000 BTU 3-in-1 Air Conditioner. This versatile air conditioner can be used as a dehumidifier, cooler, and fan all year round.
