Portable Air Conditioners
Portable ACs compared on the DOE's real-world SACC cooling number set beside the inflated box BTU, plus the room size each brand claims, single or dual hose, heat mode, and app control.
| 4.0 Entry price, entry results. It puts a hose in your window and a pocket of cool air in front of it, and asks 400 sq ft to believe in magic. | 5,300 BTU | 9,000 BTU | 400 sq ft | Single-hose | |||
| 5.6 The default cheap portable AC. It cools a small room adequately, the plastics feel it, and the control panel is the only interface you get. | 8,000 BTU | 12,000 BTU | 550 sq ft | Single-hose | |||
| 5.0 The same unit with a resistive heating element, which is the most expensive way ever devised to add warmth to a room. | 10,200 BTU BLACK+DECKER’s own product page has listed this unit at 7,700 BTU SACC/CEC; the current retail listing states 10,200 BTU SACC. We record the retail figure and flag the discrepancy. | 14,000 BTU | 700 sq ft | Single-hose | |||
| 5.2 Sells on a room-size claim more than double what its rivals promise for the same cooling; buy it for a 300 sq ft room and it is fine value. | 10,200 BTU BLACK+DECKER’s own product page has listed this unit at 7,700 BTU SACC/CEC; the current retail listing states 10,200 BTU SACC. We record the retail figure and flag the discrepancy. | 14,000 BTU | 700 sq ft | Single-hose | |||
| 6.6 Beautifully built and unusually quiet, with a remote that senses temperature where you sit, but it is heavy, expensive, and has no app at all. | 8,600 BTU | 14,000 BTU | 700 sq ft | Dual-hose | |||
| 4.6 The smallest and smartest unit here, and the one that admits it: Dreo rates it for 150 sq ft, and above that you will notice. | 5,000 BTU | 8,000 BTU | 150 sq ft | Single-hose | |||
| 6.8 A tidy, quiet bedroom unit with voice control and honest marketing; you pay a little extra for the app and drainage-free design. | 8,000 BTU | 12,000 BTU | 300 sq ft | Single-hose | |||
| 7.2 The only brand here whose room-size claim looks like it came from physics rather than marketing, plus a genuinely good app and no drain bucket. | 10,000 BTU | 14,000 BTU | 400 sq ft | Single-hose | |||
| 4.8 Quiet for its class and easy to wheel around, but 5,500 real BTU only ever takes the edge off one small, well-sealed room. | 5,500 BTU | 8,000 BTU | 350 sq ft | Single-hose | |||
| 6.4 A competent big-box workhorse with year-round use and a sane room claim; nothing about it is quiet, refined, or connected. | 10,000 BTU | 14,000 BTU | 450 sq ft | Single-hose | |||
| 5.4 Compact enough for a home office and easy to live with, but it draws real power for modest output and hums louder than the spec sheet suggests. | 7,200 BTU | 10,000 BTU | 450 sq ft | Single-hose | |||
| 6.0 Plenty of cooling per dollar and famously durable, undercut by a 700 sq ft claim it has no chance of meeting and a fan you will hear over the TV. | 10,000 BTU | 14,000 BTU | 700 sq ft | Single-hose | |||
| 7.6 The same inverter platform a generation back, often much cheaper, with no practical downside beyond a slightly older app experience. | 10,000 BTU | 14,000 BTU | 450 sq ft | Single-hose | |||
| 7.0 Cools and heats with LG’s app behind it, though resistive heating through a portable unit is a costly way to warm a room you already heat. | 10,200 BTU | 14,000 BTU | 450 sq ft | Single-hose | |||
| 7.9 LG’s inverter is quiet and its ThinQ app is the most polished here, but the single-hose design spends part of its output pulling hot air back in. | 10,000 BTU | 14,000 BTU | 500 sq ft | Single-hose | |||
| 8.3 The bedroom-sized Duo. Same dual-hose inverter tech for meaningfully less money, and 10,000 real BTU is more than most single rooms need. | 10,000 BTU | 12,000 BTU | 450 sq ft | Dual-hose | |||
| 9.0 Same excellent machine with a heat mode that turns a three-month appliance into a year-round one, which is most of what justifies its premium. | 12,000 BTU | 14,000 BTU | 550 sq ft | Dual-hose | |||
| 9.2 The reference unit: a real dual-hose path, an inverter compressor that holds temperature instead of cycling, and an app that has had years of bug fixes. | 12,000 BTU | 14,000 BTU | 550 sq ft | Dual-hose | |||
| 7.4 A design old enough to vote, with no inverter and no app, yet its dual-hose plumbing still beats most newer single-hose units in a real room. | 9,500 BTU | 14,000 BTU | 500 sq ft | Dual-hose | |||
| 6.2 Dual-hose done to a budget. The plumbing is right but 7,000 real BTU is thin for the asking price, and there is no app or inverter. | 7,000 BTU | 12,000 BTU | 400 sq ft | Dual-hose | |||
| 8.8 Matches the Midea on cooling with a sturdier chassis and better filtration; the app and setup are clumsier, and Whynter support is a smaller operation. | 12,000 BTU | 14,000 BTU | 600 sq ft | Dual-hose | |||
| 8.5 The heating version of the best-built unit here, priced high enough that you should genuinely want winter use before paying the difference. | 12,000 BTU | 14,000 BTU | 600 sq ft | Dual-hose |
How the AI score works, and who wrote it
A language model rated these, not a test lab. Every score from 1 to 10 is an AI assessment of how good the product is against the other 22 in this comparison, formed from the specifications we verified plus the published lab reviews and owner reception found while researching each one. Nobody at Slopsheets listened to, wore or plugged in any of it.
It weighs the things a spec table cannot show: how a product is actually reviewed, how well the software works, build quality, and what you get for the money. That is deliberate. An earlier version of this column was pure arithmetic on the table and it ranked a bundle of cheap boxes above a class-leading single unit, because counting hardware is not the same as judging it.
Treat it as an informed starting point and read the sourced comparison, not as a verdict. The score is relative to this comparison only, so it means nothing across categories, and it carries no price, star rating or review count. Every specification behind it is sourced and checked; the score on top of them is opinion.
