❄️ De’Longhi Pinguino PACEX130CST Smart Portable Air Conditioner Review (2025 UK Edition)
As UK summers grow hotter, the demand for premium air conditioning has skyrocketed. The De’Longhi Pinguino PACEX130CST steps in as one of the most advanced and powerful portable AC units available in the UK market. With smart controls, dual fan speeds, and top-tier energy efficiency, it’s built for users who want high-end performance without permanent installation. In this in-depth review, we explore whether this smart AC justifies its premium price tag — and how it performs in real-world UK homes.
🌬️ Powerful Cooling Performance
The De’Longhi PACEX130CST is rated at an impressive 13,000 BTU, making it suitable for spaces up to 45 square metres. That covers large bedrooms, lounges, or open-plan flats — far beyond what most portable AC units can handle comfortably.
Thanks to its Real Feel technology, the unit doesn’t just lower temperature — it also manages humidity, providing a more natural and comfortable climate. This is particularly valuable in the UK, where muggy heatwaves are becoming more common.
📱 Smart Features & App Control
One of the standout features of the PACEX130CST is its Wi-Fi connectivity. You can control the unit via the De’Longhi Comfort app, available on iOS and Android. The app allows you to:
- Turn the unit on/off remotely
- Adjust temperature and fan speed
- Set timers and cooling schedules
- Monitor current room conditions
It also integrates with voice assistants like Amazon Alexa and Google Assistant, allowing full hands-free control — a major convenience if the unit is installed in a bedroom or living room.
🔇 Quiet Operation for Large Spaces
Despite its power, the Pinguino operates at a relatively quiet 64 dB max and includes a Silent Mode for nighttime use, which brings the noise level down for uninterrupted sleep or work.
It’s not as silent as a fan-only device, but considering the cooling capacity, the sound profile is very reasonable — especially when run at lower fan speeds or scheduled for pre-cooling before bed.
📦 Setup & Portability
The PACEX130CST includes an adjustable window kit compatible with most UK window styles, plus a 1.5m exhaust hose. It’s designed for easy setup — though given its size and weight, you’ll likely want to park it in one room rather than move it daily.
Still, it comes with 360° caster wheels and side handles, so shifting it occasionally between rooms is entirely possible with a bit of effort.
♻️ Energy Efficiency & Eco-Conscious Design
This model earns an Energy Efficiency Class A++ rating — exceptional for a portable AC of this size. It uses R290 refrigerant, a natural gas with low environmental impact, and includes an Eco Real Feel mode that balances temperature and humidity intelligently to reduce energy use.
In short: it’s one of the smartest options for cooling large spaces without punishing your electricity bill.
🧼 Air Filtration & Maintenance
Beyond cooling, this De’Longhi unit includes a dust and allergen filter that’s ideal for allergy-prone households. The filter is removable and washable, helping to maintain air quality without constant replacement costs.
Maintenance is simple — clean the filter every 2–4 weeks during peak use and ensure proper ventilation around the unit to keep performance high.
👍 Pros
- High 13,000 BTU capacity for rooms up to 45m²
- Wi-Fi control with app and voice assistant support
- Energy efficient (A++ rated) and eco-friendly R290 gas
- Smart Real Feel humidity adjustment

👎 Cons
- Heavier and bulkier than mid-range models

- Requires some strength to move between floors
💡 Final Verdict
The De’Longhi Pinguino PACEX130CST is one of the most complete and intelligent portable air conditioning systems available in the UK for 2025. It offers exceptional cooling power, smart features, and impressive energy efficiency in a single, well-built unit.
It’s ideal for large rooms, heat-sensitive households, and anyone looking for a long-term, smart cooling solution that doesn’t require permanent installation. While the price may be a bit steep, its performance, quiet operation, and connectivity more than justify the investment.
