SereneLife SLPAC8 Review

This unit is highly portable and easy to install, but it's louder than most and not powerful enough to chill large or stifling hot spaces

Our Verdict

Like its higher-powered sibling, the SereneLife SLPAC8 has one of the best window interface kit designs we've seen, making for one of easiest installs of all units tested. It's lightweight, highly portable, and very energy-efficient, but the accolades end there. The SereneLife is loud for a portable AC with such underwhelming cooling capability. In fact, it's one of the loudest and least capable ACs of all units in our review. This is one to avoid if you require a lot of cooling capacity or value quiet operation.
Excellent window kit for easy installation
Relatively lightweight
Very energy-efficient
Louder than average
Single-hose design
No medium fan setting

Our Analysis and Test Results

The 8,000 BTU SereneLife SLPAC8 has above-average installation thanks to its cleverly designed sliding window interface kit. It's lightweight and highly portable, and it leads the pack in energy efficiency.

Performance Comparison

The lower-powered SereneLife SLPAC8 didn't wow us in the cooling test as it came in around the bottom of the pack. We heated the room to 82.6 degrees Fahrenheit and turned the SLPAC8 to its highest cooling setting for one hour. By the end of the test, the air temperature dropped to 77.6 degrees Fahrenheit, which is a far cry from our top scorer.

The SereneLife SLPAC8 did well in our portability and installation tests. We weighed the SereneLife SLPAC8 at just over 44 pounds. It's one of the only portable air conditioners we tested with only one carry handle positioned at the top center of the unit. While it may be light compared to other units, and carrying it around isn't terrible, we prefer units with two handles. Rolling on hard floor was nice and smooth with straight steering. Rolling on short pile carpets is fine as well, but there is more resistance on medium to high pile carpets.

Like its sister unit, the SLPAC10, installation is an absolute breeze and can be completed in around five minutes, with little more than your hands and a couple of basic hand tools.

Just like on the more powerful SLPAC10, we appreciated the packability of the SereneLife SLPAC8 for those who put their AC away at the end of the summer. All you do is unlock the tabs, remove the unit, unscrew the hose from the window panel, and simply twist off the hose from the back of the AC. Unfortunately, we were unable to find any onboard storage in our testing, so you'll have to store other components elsewhere.


The SereneLife SLPAC8 didn't perform well here. It was one of the loudest units out of all that we tested. We listened to each unit and also broke out our sound meter to measure the number of decibels produced by each AC unit.

The SereneLife SLPAC8 produced 63.7 dBa running several feet from the SPL meter with the fan on high. The fan and the compressor are both very loud compared to other units. In fact, the SLPAC8 is even louder than its more powerful 10000 BTU big sister by a noticeable margin.

Energy Consumption

The 8,000 BTU SereneLife SLPAC8 performed exceptionally well in this metric, taking top honors as one of the most energy-efficient portable air conditioners in the review.

The SereneLife SLPAC8 consumed a mere .72 KWh over an hour. Over a 90-day period with 12 hours of daily use, we calculated that it will consume 777.6 kWh and run up an approximate electric bill of $125.50. It reigns supreme as one of the most efficient and affordable portable ACs we've tested.


The lowest portion of the review score (5%) is how we rated the convenience features of each AC. The SereneLife SLPAC8 was one of the lowest scorers in this metric.

This unit does have all of the basics you need to run it, like vertically adjustable air vents, basic modes, a remote control, and a highly legible screen, but the SereneLife SLPAC8, but it fell short compared to other units with smart capabilities that allow users to control their device remotely.

Should You Buy the SereneLife SLPAC8?

The SereneLife SLPAC8 isn't powerful enough to cool large rooms or rooms in scorching hot climates, so we only recommend it for small spaces and to those who value energy efficiency and portability above all else.

What Other Portable Air Conditioner Should You Consider?

If you're looking for easy installation, good portability, and better cooling capability, check out the SereneLife SLPAC10 for a few more bucks. If you want decent cooling and the quietest portable AC in the game, go for the well-rounded LG LP1022FVSM.
