Our Verdict
If you’re looking for the lowest possible power draw, the Serenelife SLPAC10 is a portable air conditioner that uses less power, so you can run it longer without worrying about raising your bills. Its power draw of 0.96 kWh makes it very economical to run, while its cooling capacity of 10,000 BTU makes it suitable for smaller spaces like bedrooms, home offices, or dorm rooms.
Despite its small size, the Serenelife SLPAC10 effectively maintains a comfortable temperature. The cooling speed, rated at 10 minutes per degree, allows for moderate climate control, ensuring that you can create a pleasant environment in a reasonable time frame, though if you’re looking to cool down your room faster (or just live somewhere much hotter), the Whynter ARC-1230WN cools much faster and runs quieter, but at the cost of a couple of hundred dollars more.
Still, the operating noise of 59.0 decibels is perfectly fine, coming in no louder than a typical conversation, and if the unit is on the other side of the room, you’ll barely notice it. If you’re very sensitive to noise, quieter models exist (like the ARC-1230WN), but A/C units can only get so quiet before they start trading power for noise.
Serenelife’s SLPAC10 is a reliable portable air conditioner that combines energy efficiency, moderate noise levels, and decent cooling power. While it might not be the fastest at cooling, its flexibility and ease of use make it a solid choice for smaller spaces or temporary setups. If you need a portable air conditioner that is economical and relatively easy to move, pick one up.

Our Verdict
The Whynter ARC-14SH is a powerful portable air conditioner with a cooling capacity of 14,000 BTU, making it suitable for larger rooms and spaces. With a cooling speed of 7 minutes per degree, the Whynter ARC-14SH provides relatively fast climate control for the rooms it’s designed to operate in. Between its high capacity and good cooling speed, the unit is ideal for living rooms, large offices, or studio spaces.
However, its energy efficiency ratio (EER) is poor, putting its power draw at 4.90 kWh. This higher draw does make sense, though—given the unit’s higher capacity, a higher power draw tends to be expected. The operating noise of the ARC-14SH is moderate, at 59.5 decibels. This noise level is common among larger units, but it still stays at a level around that of a typical conversation.
A unique feature of the ARC-14SH is its versatility, as it can be used as a heater. If you live somewhere that has cold winters and hot summers, it’s a fantastic dual-purpose unit.
The ARC-14SH justifies its high price tag with versatility and performance. The portable air conditioner features high cooling capacity, decent cooling speed, additional heating functionality, and acceptable noise levels, making it a perfect all-season pick.

- Derek Hales – Modern Castle, LinkedIn
Interested in a comprehensive analysis of our data sources? We’ve got you covered. Below, you’ll find a detailed list of every air conditioner review website we’ve identified, organized by their respective Trust Ratings from highest to lowest. But we didn’t stop there. We’ve meticulously reviewed each publication and verified the data by checking whether the authors have bio links to MuckRack or LinkedIn. We’re committed to not only checking the facts but ensuring their veracity.
Air Conditioner Test Data & Results
1. Operating Noise (dB)
All air conditioners make noise, this is a fact. Generally speaking, the more airflow an A/C unit has, the louder it’s going to be, and (logically) the more capable it is of cooling larger spaces (or smaller spaces more quickly.) Quieter A/C units are less disruptive and are often more attractive if you like a more peaceful home, but if your cooling needs are very high, be ready to see higher noise levels.
It’s for this reason we recommend an operating noise level around 55 dB or less. This puts it below the noise of a typical conversation and allows the sound to fade away into being background noise or even white noise. Higher volumes can be distracting, especially if you’re very sensitive to droningsounds.
Operating Noise
< 55 dB
Acceptable range of performance
Definition: How much noise the unit makes while it is under normal operation.
Units of Measurement: dB (decibels)
Tools to Measure: Sound pressure level meter or decibel meter
Why It’s Important:
Loud units are annoying and disruptive, and quiet units fade into the background more easily.
Operating Noise (dB; lower is better; 0 = No Data)
2. Cooling Speed (Min/Deg)
Cooling Speed
> 5 min/deg
Acceptable range of performance
Definition: How long it takes a unit to successfully lower the temperature in an area by one degree, measured in minutes.
Units of Measurement: Thermostat, timer
Tools to Measure: Speed-checking software
Why It’s Important:
If you need rapid cooling, better cooling speeds mean you spend less time suffering heat and more time enjoying the breeze.
There are multiple factors that influence how quickly an air conditioning unit is going to cool down a space. The size of the A/C, if it’s in good condition or not, the size of the room, and the actual settings chosen (for example, using a quiet mode or a performance mode.)
We recommend a cooling speed of at least 5 minutes per degree lowered, but faster cooling speeds are always welcome. It’s important to note that this is for when you use the A/C unit in a room that it’s designed for. If you stick a very small A/C in a huge room, the cooling speed is going to be abysmal, and if you put an oversized unit in a closet, you’ll be putting up some impressive numbers, but neither are realistic.
Cooling Speed (Min/Deg; lower is better; 0 = No Data)
3. Power Draw (kWh)
The size of your A/C unit is often the biggest determining factor behind how much power it draws – bigger units with bigger mtors draw more power. But units that are the same size might not be built the same, and the power draw they exhibit can vary wildly in some cases, even when they’re on roughly the same settings.
We generally recommend a power draw of less than 1 kWh, but lower is better – provided it doesn’t impact your unit’s ability to cool. Some units (especially larger ones) will require more power no matter what though, especially if they have larger motors or claim to push more CFM and actually deliver on that claim.
Power Draw
< 1 kWh
Acceptable range of performance
Definition: How much power the unit draws while under normal operation, measured in kilowatt-hours.
Units of Measurement: kWh (kilowatt-hours)
Tools to Measure: Power meter
Why It’s Important:
High power usage means higher power bills when using your A/C, so the power draw should be as low as possible without sacrificing cooling performance.
Power Draw (kWh; lower is better; 0 = No Data)
Best Portable Air Conditioners: Mistakes To Avoid
- Neglecting Room Size: Underestimating the size of the room can result in an underperforming air conditioner, while overestimating can mean spending more than necessary. Measure your room’s dimensions and compare them to the manufacturer’s recommendations to ensure proper cooling capacity.
- Overlooking Ventilation Requirements: Not planning for proper ventilation can render your portable air conditioner ineffective. These units need to expel hot air outside, so ensure you have a window or another suitable venting option available. If a window is not an option, learning how to vent a portable air conditioner without a window is crucial. Consider alternatives such as venting through a sliding door, ceiling, or wall to maintain the unit’s efficiency. Proper ventilation ensures that your portable air conditioner can effectively cool your space.
- Forgetting About Energy Efficiency: Ignoring the energy efficiency rating of a portable air conditioner can lead to higher electricity bills. Look for units with a high EER (Energy Efficiency Ratio) to save money over time and reduce environmental impact.
- Not Checking Noise Levels: Overlooking the noise level of a portable air conditioner can lead to a disruptive environment. Check the decibel (dB) rating to ensure the noise level is acceptable for your space, especially if it will be used in a bedroom or office.
