{"slug":"best-portable-air-conditioner-under-300","title":"Best portable air conditioner under $300?","question":"What is the best portable air conditioner you can buy for under $300?","verdict":"As of 2026-07-07, ChatGPT, Claude and Gemini collectively rank BLACK+DECKER BPACT08 #1 for portable air conditioner under $300 on ModelsAgree by aggregate score. The models' case: Reliable cooling performance in rooms up to 350 square feet, compact footprint, and an easy-to-install window kit. The models' main caveat: A longer exhaust hose to allow more placement flexibility away from the window. The strongest alternative is Midea MAP08R1CWT — best cooling-per-dollar of any sub-$300 unit, quiet operation (~52 dB), reliable compressor, easy-roll casters and window kit that actually seals. Not unanimous: ChatGPT picks TCL Smart Portable Air Conditioner; Claude picks Midea MAP08R1CWT.
