Our Verdict
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.
Cooling
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.
Portability/Install
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.
Noise
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.
Convenience
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 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, still within an affordable price range, check out the SereneLife SLPAC10, which is only a few more bucks. If you want decent cooling and the quietest portable AC in the game, go for the well-rounded LG LP1022FVSM.
