De'Longhi Pinguino PAC EX105

Venting and windows

A single exhaust hose pushes hot air out through the window, which pulls a slight vacuum in the room; warm air leaks back in through every gap. The window seal decides whether you keep the rated output, so budget €15 to 30 for a cloth seal kit that matches your window type.

What stands out

• The only portable monobloc rated A+++ on the EU label; De’Longhi quotes up to 38% less energy than a conventional unit
• Real inverter cooling for rooms up to about 40 m², with propane (R290) refrigerant ready for the 2027 F-gas rules
• Sold by more than a dozen EU retailers, so it is easy to price-check before buying

Why it leads the one-box class

FAZ Kaufkompass named the Pinguino PAC EX105 its mobile air conditioner test winner in 08/2025, on price-to-performance and low running cost. testberichte.de aggregates its reviews at 2.0 ('good'). The A+++ cooling label sits at the top of the monobloc scale (Regulation 626/2011), where most portables land at A; De'Longhi quotes up to 38% lower consumption than a conventional unit.

It is still a single-hose machine: it pulls room air out through the window kit, so the window seal decides whether you keep the rated output. With a tilt-and-turn window, pair it with a cloth seal kit.
