In detail: De'Longhi Pinguino PAC EX100, 10000 BTU portable air conditioner
The De'Longhi Pinguino PAC EX100 Silent belongs to the Italian manufacturer's best known line of portable air conditioners, on the market since 2016. It is a classic monobloc unit, with an exhaust hose to run through a partly open window using the supplied kit, delivering 2.5 kW (10,000 BTU/h) of cooling capacity for rooms up to 110 m³, at A++ energy class.
Its Real Feel technology is the centrepiece of the Pinguino range: it continuously monitors temperature and humidity to automatically adjust the unit's operation, with claimed energy savings of up to 30% compared to standard manual control. The dehumidifier function, able to remove up to 24 litres of water per 24 hours, makes it a useful appliance even outside heat peaks, for rooms prone to damp.
Control runs via an LED touch panel or a supplied remote, with a 12-hour programmable timer and 3 fan speeds. The unit is ready to use straight out of the box, with no complex assembly, thanks to built-in handles and castors and an included window kit. The R290 refrigerant, more environmentally friendly than traditional gases, rounds out this approach.
The "Silent" name deserves some nuance: while noise stays reasonable once the target temperature is reached, the compressor at full load remains audible, a point regularly raised in customer reviews and confirmed by several independent tests, which judge the name somewhat optimistic next to newer competitors. The lack of WiFi or mobile app connectivity, and a remote seen as overly basic with no set-temperature display, round out the limitations worth knowing: choices that feel a little dated, the unit not having evolved since launch. Despite this, its reputation for reliability and genuinely effective cooling make it a safe bet in the premium portable air conditioner segment.

Comparison
In a comparable price range (£300 to £800 depending on promotions), the De'Longhi Pinguino PAC EX100 regularly comes up against the Olimpia Splendid Dolceclima, the other big Italian name in portable air conditioning, in searches like "Pinguino vs Dolceclima". Here is how the two compare, based on the public specifications of both manufacturers.
| Criterion | Pinguino PAC EX100 | Dolceclima 10 HP WiFi |
|---|---|---|
| Cooling capacity | 2.5 kW (10,000 BTU/h) | 2.6 kW (≈10,000 BTU/h) |
| Energy class | A++ (cooling only) | A (cooling and heating) |
| Reversible (heating) | No, cooling only | Yes, heat pump |
| Built-in WiFi | No | Yes, OS Home app |
| Dehumidifying | Up to 24 L/24h | Not rated by the manufacturer |
In short, the Pinguino PAC EX100 wins on pure energy efficiency (A++ vs A), but stays a cooling-only unit with no remote control app. The Dolceclima bets on versatility, reversible for supplementary heating and WiFi-connected, at a slightly lower energy class. The choice mostly comes down to how much you value connectivity against raw energy efficiency.

Our tester's verdict: Christophe Delpuech
The Pinguino PAC EX100 has been racking up reviews since 2016, and the pattern that emerges is fairly consistent: an effective air conditioner that genuinely cools, but a "Silent" name best taken with a pinch of salt. Several users confirm it runs reasonably quietly once the target temperature is reached, but the compressor at full power stays clearly audible, much like nearly every monobloc portable unit. The dehumidifier function is regularly praised as a real plus, useful outside heatwave season too. The point that comes up most in less favourable reviews concerns the remote, seen as basic, with no display for the set temperature, and the total absence of WiFi or app connectivity, a choice that feels a little dated next to newer models. One faulty unit was also reported, barely cooling at all, with the buyer describing Amazon's after-sales support as unsatisfactory, an isolated case but worth knowing about. For a room of 20 to 40 m² in typical summer use, the Pinguino EX100 remains a solid, proven choice, carried by De'Longhi's established reputation in this segment, as long as you don't expect absolute silence from it.
