Best Portable Air Conditioners: Full Reviews
These reviews offer more detail and a fuller description of each of the best portable air conditioners and evaporative air coolers.
Quick distinction: A portable AC is a true air conditioner. It uses refrigerant to collect heat indoors and dump it outside, cooling the inside air by removing heat from it.
An evaporative air cooler does not remove heat from the space. Instead, it cools people in the room through evaporation – just as moisture evaporating off your skin makes it feel cooler. The technology is fully explained below in the Portable AC Buying Guide.
Our Rating System: Here is what we looked at in choosing our list of the Top 12 Portable Air Conditioners & Coolers. We rate each category from 1-5 Stars, though the units in this list are all 4 to 5 stars since they are top products.
- Quality: We looked for hardworking, durable models built with quality parts. The units chosen have a track record of reliability.
- Performance: Fast cooling, removal of a high volume of moisture, various modes in addition to AC such as Dehumidify Mode, Fan-only Mode and/or Heat Mode. When Dehumidify Mode, aka Dry Mode, is used, moisture is removed from the air. Heat is removed too, but instead of it being exhausted from the room, which would cool the room, it is returned to the room. Air temperature doesn’t drop. Dry Mode is ideal for cool days with high humidity that makes the air chilly, damp, clammy. You wouldn’t want colder air, but getting rid of the damp makes the room more comfortable.
- Features: Most of the portable air conditioners on the list are evaporative units. This means that the moisture removed from the air is evaporated out the exhaust hose. Again, this is regarding the ACs. The Evaporative Coolers use the term too, but in a different manner, which is explained below. In addition, most ACs on the list have 24-hour timers, remotes with all the unit functions, multiple-speed fans
- User Reviews: We look at ratings and reviews from many platforms including Amazon. It is useful to see what actual users of the products are saying about them. Fakespot is occasionally used to analyze whether the reviews seem legitimate or are faked. We do not consider reviews on the manufacturer sites. Best Pro: This is the user review that best summarizes those with a positive experience. Best Con: This is the user review that best summarizes those with a positive experience.
- Overall Rating: The ratings from the categories above are averaged for an overall score.
- Best Use: This is where the best fit for each AC/cooler is defined.
- Size and Performance Options: Portable ACs are not one-size-fits-all. That’s why we give you great options in various sizes, performance and cost.
OK, on to the Full Reviews.
#1 Ivation 12,000 BTU Portable Air Conditioner – Powerful AC Unit & Dehumidifier
This is the best portable air conditioner available today. It is loaded with features, has 5 modes that allow you to customize indoor comfort and delivers outstanding performance and quality. On top of that, it is a really good value, given its competitive cost.
The noise level on this unit is about average. It runs at 55 decibels on high and estimated 52 dB on the lowest setting. There’s a normal amount of “buzz” when the compressor kicks on.
If quiet operation is your top priority in a good portable air conditioner, see the Quilo and JHS models below. They are the quietest portable ACs on this list. We’ve also completed a Review and Buying Guide of the Quietest Portable Air Conditioners.
- Quality: 4.5 – Very good build. The unit has a solid feel. Caster wheels, window kit and hose should last indefinitely.
- Performance: 5 – This unit’s modes are Air Conditioning, Humidification (drying the air without chilling it), Fan-only for moving air, Sleep Mode for saving energy while sleeping and Auto Mode – set the temperature you want, and the unit will automatically run in the right mode to hit that temperature based on the conditions in the room.
- Features: 5 – It is an evaporative portable air conditioner, so most of the condensation evaporates out the exhaust hose. If you’re using the unit as a dehumidifier, then you might want to attach a garden hose and run it to a 5-gallon pail or, if available, a floor drain. This Ivation portable air conditioner has the other ‘bells & whistles,’ a full-feature remote, 24-hour timer and one of the longest exhaust hoses available at about 5 feet. The long hose gives you a little more flexibility in placing the AC where it won’t be in the way or where it delivers the best cooling for the room.
- User Reviews: 4.5 Reviews are 80% to 83% positive across the platforms. Does that seem low? They are quite good for a portable AC.
One of the truths about portable air conditioners is that window air conditioners are generally rated higher. We cover that issue below when the two appliance types are compared.
- Best Pro: “This AC cools our south-facing bedroom pretty quick in the evening and doesn’t wake me up tho I’m a light sleeper.”
- Best Con: “Does not effectively cool my 425 square foot insulated garage. On a 95 degree day in Scottsdale AZ I’m lucky if it gets it to 85.” [Editor’s Note: This is a common concern for all portable air conditioners, that they are overrated for how much space they can cool. The section below on ASHRAE vs. DOE/SACC BTU ratings clarifies it. Plus, outside temperature and how well the room is insulated are major factors in how well any air conditioner can perform. Garages, even insulated garages, often don’t have the level of insulation a home does.]
- Overall Rating: 4.75 out of 5
- Best Use: Bedrooms, offices and other enclosed rooms (vs on open floor plan) up to about 350 square feet. It’s also a good budget portable air conditioner, even though it’s features and performance are excellent.
Did you know? Fakespot is a website that analyzes the truthfulness of ‘user reviews’ online. The site gives this portable AC page an ‘A’ rating for genuine reviews.
#2 Ivation 12,000 BTU with Wi-Fi

Portable Air Conditioner Buying Guide
In this Buying Guide, we’ll cover several important topics that should assist you in your buying decision.
Portable vs Window Air Conditioners with Pros & Cons
In general, homeowners give higher ratings to window air conditioners than to portable air conditioners.
Perhaps these portable air conditioner pros and cons will shed light on why this is true.
Portable Free Standing AC Pros Compared to Window Air Conditioners
- They can be moved around a little bit, as their hoses are 3.5 to 5.5 feet in length
- They are easier to move from room to room since they have caster wheels
- They take up less window space, so the view isn’t as obscured
- There no risk of them falling out of the window and causing injury or damage
- Homeowner Associations do not object to portable AC window kits, but many object to window air conditioners
Portable AC Cons Compared to Window Air Conditioners
- Portable ACs cost more for units that are the same size
- They do not cool as effectively, since they pull warm air into the house (See BTU Ratings – below)
- They have a higher rate of mechanical failure than window ACs
Also Read: Window vs Portable AC: Which One is Better?
Portable ACs vs Whole-house ACs
If you have central AC, is there a place in your home for a portable air conditioner?
Potentially yes. Here’s what a portable AC can do for you. The same advantages apply to a window AC.
- These units can cool rooms that aren’t adequately reached by central AC – those rooms that face west or south, or second-floor rooms, rooms that always seem warmer than the rest of the house.
- Cooling just the room you’re in, such as a bedroom at night or home office during the day, allows you to turn up the thermostat on the central AC with the result of using less energy at less cost and still remain comfortable.
Portable AC vs Evaporative Air Cooler
Evaporative air coolers are sometimes called mini air conditioners or personal air conditioners. They are not air conditioners. Here’s an overview of how they work.
1. Water is poured into a tank (and some also have garden hose connections for constant operation).
2. The water is wicked up or absorbed by absorbent material.
3. A fan pulls air through the material which has the effect of causing heat in the air to evaporate water out of the absorbent material. As you likely know, evaporation removes heat, and that makes the air cooler. Think about water evaporating off your skin – it makes your skin cooler. The cooler air is blown out of the unit. A good evaporative air cooler can lower the temperature of the air by 8 to 20 degrees.
Portable AC Advantages
- They remove moisture from the air. An evaporative air cooler adds moisture.
- They remove heat from the room. An evaporative air cooler blows cooler air in one or two directions, but the heat removed remains in the room, just not in the air you feel blowing your way. In other words, in an enclosed room, the temperature cannot be lowered using an evaporative cooler.
- They work in any region of the country, including very humid areas. Evaporative air coolers are effective where humidity is relatively low. Where humidity is high, the water won’t evaporate as well, if at all, at evaporation is necessary for removing heat from the air.
Evaporative Cooler Advantages
- They generally cost less than a portable AC.
- They are lighter and easier to move from place to place.
BTU Ratings: ASHRAE vs US DOE Ratings
This is the so-called elephant in the room that some portable AC manufacturers don’t like to discuss.
These units simply are not as efficient as other AC types. Here is why – and why there are two separate BTU rating systems.
The problem: When air is exhausted out the window hose, it creates negative air pressure indoors.
The result: As air goes out, air is sucked indoors through any drafty location. No home is airtight. The air drawn in is warm, humid air.
The bottom line: The effectiveness of a portable AC is significantly diminished by the air infiltration.
Two Rating Systems
The American Society of Heating, Refrigerating and Air-Conditioning Engineers (ASHRAE) tests the basic effectiveness of air conditioners of all types, as it has done for decades. One test – How many BTUs of heat can a unit remove from the air per hour. The test does not factor infiltration – how much heat is sucked back into your home.
This infiltration is not a factor with a window AC or central air conditioning.
At some point, this built-in inefficiency came to the attention of the US Department of Energy. For the sake of giving an accurate rating to consumers, the DOE developed the Seasonally Adjusted Cooling Capacity (SACC) that does account for infiltration.
While there isn’t a formula that covers all portable air conditioners, the DOE SACC rating is usually 50% to 60% of the ASHRAE rating for how many BTUs the unit can remove per hour. Examples included for models we’ve reviewed are:
- 14,000 ASHRAE = 7,500 SACC
- 12,000 ASHRAE = 6,500 SACC
- 10,000 ASHRAE = 6,000 SACC
- 8,000 ASHRAE = 4,500 SACC
- 6,000 ASHRAE = 3,000 SACC
Not all product pages list the SACC rating. Many list them both. Only a few list just the SACC rating. If there is only one BTU rating given, it is probably the ASHRAE rating and you should consider that the SACC rating is about half.
You can also go by the chart in the next section.
Sizing your Portable Air Conditioner
It is important to buy a unit rated to serve the amount of space you have – or more. With central air conditioners, you should not choose one that is too big for your home. But because of efficiency issues with portable free standing air conditioners, going a size up isn’t an issue.
This chart is a starting point. See the addition points below it for properly sizing a portable AC.
We recommend that you choose a unit that is 1,000 BTUs larger than the chart recommends for each of these issues:
1. Ceilings higher than 8 feet.
2. The room faces south or west and isn’t shaded by trees.
3. Is a room often occupied by 3 or more people.
4. Is for a kitchen, since cooking makes the room hotter and more humid.
How to Make a Portable AC More Efficient & Effective
These home efficiency tips will help you air condition and heat your home more efficiently.
1. Make sure your home’s attic has the appropriate amount of insulation.
2. Use weather stripping around drafty doors and windows.
3. When you upgrade windows and doors, choose those with better insulation values.
Specifically for portable air conditioners:
1. Choose one with a programable timer, so you can determine when the unit comes on and shuts off. That way, you don’t have to leave it on while you’re away to have the space comfortable when you get home. Program the AC to come on an hour before you arrive.
2. Consider a unit with WiFi. It is the surest way to reduce unused air conditioning. When you’re on your way home, use the app to turn on the air conditioner or to turn down the unit’s thermostat to a more comfortable level.
3. Use the foam that is included with your window kit to create as airtight a connection as possible.
