Cooling a single room without committing to a fixed install, the Ariston MOBIS 8 sits in the brand’s home climate range and competes with other 8,000 BTU portable units from the likes of De’Longhi, Meaco and ElectriQ. It’s aimed at renters, flats and home offices where you want short-term, targeted cooling, then pack it away when the weather turns. The A energy class rating is a useful signpost if you’re trying to keep running costs sensible for occasional summer use, though any portable air conditioner will still draw more power than a fan.

Who is this for?

Best suited to smaller to mid-sized rooms where heat builds up in the afternoon. Like all portable models, it works best when you can vent warm air out of a window, so check you’ve got a suitable opening and space near it.

• 8,000 BTU cooling: appropriate for single-room cooling rather than whole-home coverage.
• A energy class: helps compare efficiency across similar portable units.
