Our Verdict

The SereneLife SLPAC10 offers one of the best values of any of the models we tested. It offers solid cooling performance, and its combination of convenience and low energy consumption make this an attractive buy. Not only is this an A/C unit, but it can function as a fan and a dehumidifier. It does run a bit on the noisy side, but all in all, it's a quality and versatile device.

Pros Great value, highly portable, performed well in our energy-efficiency test, solid cooling performanceVery quiet, decently portable, solid cooling performanceEnergy efficient, easily portableEasy to move, decent energy efficiencyInexpensive, relatively light
Cons Runs on the louder sideExpensive, bulky window insertUnderwhelming cooling abilitiesPoor cooling abilities, noisyPoor cooling capabilities
Bottom Line You'll save cash and receive exceptional performance, though it does run a touch louder than othersIf you live in a consistently hot climate, this is our favorite dual-hose portable ACThe lower cooling abilities do not quite make up for the energy-efficient capabilitiesThis is an expensive machine that is easy to move around but ultimately offers poor cooling abilitiesAn affordably priced model that is sufficient for smaller rooms, but has subpar cooling capabilities

Our Analysis and Test Results

Cooling Power


Our most important set of assessments focused on the relative cooling power of each product. For this test, we used a 161 square foot room for our side-by-side tests and based scores on the temperature drop each unit could achieve after an hour. We heated the room to approximately 80 degrees Fahrenheit before the test using a space heater and only tested when the outside temperature was between 80 and 85 degrees.


This A/C is rated for rooms up to 350+ square feet and is a 10,000 BTU model. It managed to achieve a temperature drop of 11°F over the course of an hour, with 8.8 of that drop achieved in the first 20 minutes.


However, this unit's performance plateaued at 71°F, and it didn't cool the room any further in our test. You'll want to take into account the room you intend to cool and if this temperature range is suitable for your needs.

This model is one of the easiest to set up.

Portability


Our next round of evaluations focused on how easy it is to move around each of these air conditioning units, as they are all allegedly portable. We based scores on how easy it is to roll around, how hard it is to carry, and how difficult it is to move the window insert between rooms. The SereneLife did quite well, earning one of the best showings of the whole group.


This air conditioning unit rolls around fairly effortlessly, smoothly traversing our test room without issues. We also liked that it isn't overly difficult to carry around the SereneLife, at least, not compared to the heaviest units we have tested. This machine still weighs in at over 50 pounds, so it isn't going to be fun to carry up a flight of stairs by any means.


The handles feel fairly ergonomic, but they are a little on the shallow side and lack any grippy material, so your fingertips may start to get tired after a bit or slip if your hands are sweaty at all.

The SereneLife's window insert is one of our favorites, making it a breeze to transfer between windows. It has a lever opposite where you insert the hose that locks it into position, allowing for a tool-free installation and removal.

We love how easy it is to install the SereneLife's window insert.

It can adjust in size from 37" to just over 50," but we did wish that it came with some foam tape to help seal any gaps.

Noise


Our last series of tests looked at how loud each of these air conditioners are. Unfortunately, the SereneLife was not the highest performer in this metric.


We moved around our sound level meter to find the loudest spot in the machine when at its different operating modes and measuring at a distance of four feet away.


This AC is on the louder side — enough that it could be difficult to carry on a conversation with someone in a normal voice if you were standing right next to it.

Energy Cost


Our final series of tests looked at the amount of energy each air conditioner consumed. We used a power meter to measure the average consumption for 30 minutes for each unit on both low and high power operating modes, then came up with a projected cost after operating them for 90 days. We assumed that you ran each unit on high power for two hours to start the room cooling off, then kept it on low for another 10 hours to maintain the temperature. Costs were calculated using an average price per kilowatt-hour of $0.1315.


Our projected cost would be a little more than $116 at the end of the 90-day period based on our assumed usage profile and average electricity cost.


Value


If you are shopping for a new portable air conditioner on a budget, then we would strongly recommend checking out the Serenelife. It holds its own with models that cost quite a bit more and isn't too power-hungry when it comes to energy consumption. This multi-use machine not only acts as an air conditioner but also can operate in a fan-only or dehumidifier mode, giving you even more bang for the buck.

Conclusion


The Serenelife SLPAC10 is a good choice if you are shopping on a budget and looking for a model that is one of the easier options to move between different rooms. It performed quite well in our energy consumption test, making it an even better value, and it offers decent cooling performance. This makes it a great option if you are only using it on the hottest days of the year and you don't routinely hit triple-degree temps, but we might suggest a model with a little more cooling power if you reside in the hottest climates.
