20 square meters, or 45 — and cooling only, or heat as well

Temprium YPK11S-07C/3-W vs Gymax KU65297IJ-BMDE

Is this a bedroom, or a large open-plan room that also needs heat in the shoulder seasons?

By

Both are portable, single-hose air conditioners, and that's roughly where the similarity ends. The gap in capacity, price and confirmed availability between them is the largest of any pairing in this family.

A tick marks the better answer on that line only. Counting ticks does not decide the page — the two verdicts below do, because these products answer different questions.

Who should take which

Buy the YPK11S-07C/3-W

Take the Temprium for a bedroom or small room up to about 20 m (66 ft)² — it covers app and voice control at the lowest price in this family, and is confirmed for sale across four European markets.

KU65297IJ-BMDE

No amazon.com listing was found for this one. We hold references for other markets but none for the United States, so it may not be buyable here — which is the first thing to weigh against anything below.

Take the Gymax only for a genuinely larger room that also needs supplementary heat outside summer, and only after confirming it's actually in stock in your market — at the time of checking it was listed with a live offer on Amazon.de alone, of six marketplaces checked.

The questions that keep coming up

Is the Gymax really six times the price for double the BTU?

Roughly, yes, on the figures we checked: ≈240 € against ≈1,600 €, for 7,000 BTU against 16,000 BTU. The price gap isn't purely about BTU — the Gymax also adds a heating mode, a larger stated room coverage and WiFi/app control the Temprium doesn't publish alongside it.

Why is the Gymax only confirmed on one market?

Keepa data showed a valid New-condition offer only on Amazon.de at the time of checking; on France, Italy, Spain, the US and the UK the ASIN wasn't found as a listing at all — a different situation from being listed but out of stock. Confirm current availability before planning a purchase around it.
