The shortlist

Portable air conditioners worth buying

A small, current list rather than a wall of options. For a pick matched to your exact room and window, run the finder.

Units are chosen from independent tests (Stiftung Warentest, testberichte.de, UK reviews) and real EU retailer availability, not Amazon best-seller lists. The retailer line on each card shows where it is sold; prices are indicative starting points in EUR and move with the season, so check the retailer for live stock. Last reviewed 2026 / 06.

Mobile splits

Outdoor module, quietest and most efficient, and the easiest to vent through an awkward window.
