Whynter Elite ARC-122DS Dual-Hose Portable AC
Two whitelisted testers cover this exact model. Wirecutter (republished on Engadget, 2018 hands-on lab test of eight finalists) names the Whynter Elite ARC-122DS its top pick, praising its quiet dual-hose operation and lowest-in-field infiltration draw. Reviewed's 2026 guide (updated 2025-06-23) states the ARC-122DS 'rose to the top as the best portable air conditioner' for cooling, room coverage, and value. Neither accessible page printed a per-model numeric lab measurement for the ARC-122DS itself. (2 sourced reviews, 2 lab-tested.)
Praised: Strong cooling / top overall pick among tested portable ACs; Quiet for a dual-hose unit (some of the quietest decibel figures); Dual-hose efficiency; drew the least infiltration air of the field.
Flagged: Wirecutter stresses portable ACs are inherently inefficient and can struggle in very hot weather, even this top pick; Cooling performance in this category is unusually hard to measure objectively (Wirecutter never developed a reliable per-model cooling metric); No numeric per-model lab measurement was printed for the ARC-122DS on either accessible page.
