The Vremi 10,000's only notable feature is the ability to program start and stop times. The user interface on this appliance is a little odd, as the screen only displays the target temperature and not the current room temperature. It is relatively quiet, but has poor cooling abilities compared to its high operating expenses and is awkward to move around. All in all, we would recommend you look at a few other portable units in our review of the best portable air conditioners before choosing this model.Editor's Note: This review was updated on April 21, 2022, to outline which models we would recommend over this one.

Our Analysis and Test Results
Cooling power is, of course, the hallmark ability of a quality AC unit. The Vremi, while not the bottom of the barrel, fell pretty far down on the list in terms of cooling power. Our testing room started at 80.74 degrees, and after running the machine for an hour, cooled the room down to 72.37 degrees. This gave us a total temperature reduction of 8.37 degrees, putting this unit toward the bottom of our fleet.
The built-in grips on the Vremi are tiny. The small grips, combined with a very uneven weight distribution, make this home appliance awkward to pick up. The saving grace for this machine is its lower weight of 54 pounds — it's of the lighter units to pick up. Getting this unit set up in a window is straightforward but requires a screwdriver.
The low-level hum produced by the Vremi should be a non-issue for all but the most sensitive to noise. The compressor has a slight rattle when it runs but is still very quiet overall. It produced 58 dBA when we measured its sound output on our decibel reader, which makes it objectively one of the quieter units. Subjectively, the low rattle kept it from scoring higher in this metric.
The Vremi is moderately expensive to operate. Assuming you run this machine for 12 hours a day for three months, your operational costs will be right around $132. When you factor in its poor cooling power, it doesn't feel like you're getting your money's worth.
Should You Buy the Vremi 10,000 BTU?
As our overall lowest scoring model, the Vremi is a tough sell. It's awkward to move around, expensive to run, and has subpar cooling abilities, leaving a lot to be desired.
What Other Portable Air Conditioners Should You Consider?
The AC unit we recommend over all others is the SereneLife SLPAC10. This model has a great energy cost to cooling ratio and has an approachable sticker price. If you are looking for maximum cooling power regardless of energy expenditure, check out the Whynter ARC-14SH, which will suit those in the hottest climates very well.
