Four units, one number in common: every one claims 14,000 BTU. That is where the similarity ends. Read past the sticker and the real cooling splits them. The dual-hose Midea Duo does a true 12,000 SACC, while the three single-hose units land near 10,000 once you find the DOE or SACC rating. The dual hose is the tell. It vents with outside air, so the Midea cools faster and quieter than the rest. Only one of the four, the BLACK+DECKER, is in stock as of this review.
For a portable AC, two things decide everything and neither is the ASHRAE number on the box. First, the hoses. A single-hose unit like the LG, Frigidaire and BLACK+DECKER blows cooled air out the window and pulls warm air back in through the gaps, so it works harder in a hot room. The dual-hose Midea Duo avoids that and adds an inverter compressor, which is why it hits 42 decibels where the others sit higher. Second, the honest rating. SACC and DOE run 30 to 40 percent under ASHRAE, so a 14,000 badge is really a 10,000 to 12,000 cooler. Match that number to your room, add up the smart features last, and the ranking sorts itself.
Which of these portable ACs should you buy?
Buy on real cooling and hoses, not the matching 14,000 badge. Right now the only one you can actually get is the BLACK+DECKER, and it is a sound choice: 10,200 SACC, smart control, and a Follow Me remote that reads your temperature, not the unit’s. If you can wait for stock, the Midea Duo is the better machine on every count that matters, dual-hose, inverter-quiet, and a true 12,000 SACC. The Frigidaire adds an air ionizer and sleep mode if clean air is a priority, and the LG leans on the slick ThinQ app. All three of those are single-hose and out of stock. Pick the BLACK+DECKER to buy today, or set a stock alert on the Midea.

Frequently asked questions
Do all 14,000 BTU portable ACs cool the same?
No. That number is the inflated ASHRAE rating, identical here by coincidence. The honest SACC or DOE figure separates them: the dual-hose Midea Duo does a real 12,000 SACC, while the single-hose units land nearer 10,000. Same badge, different cooling.
Is the Midea Duo worth waiting for over the in-stock BLACK+DECKER?
If quiet and efficiency matter, yes. The Duo’s dual hose and inverter make it cool faster, run near 42 decibels, and use over 40 percent less energy than the federal standard. The BLACK+DECKER is the better answer only if you need cooling now, since it is the one in stock.
What is an air ionizer on a portable AC?
It charges airborne particles so they clump and drop out of the air, cutting dust and some allergens. The Frigidaire here includes one. It is a mild air-quality bonus, not a replacement for a real air purifier, and it does not affect cooling.
How big a room will these cool?
Size by the SACC or DOE number, not ASHRAE. The single-hose units near 10,000 suit a medium room around 350 to 450 square feet if it is well sealed. The dual-hose Midea’s 12,000 SACC handles a genuine large room up to about 550. A leaky or sunny room drops those figures, so size up if in doubt.
