10 Best Portable Air Conditioners

This portable air conditioner offers 9000 BTU cooling power, making it suitable for small to medium rooms up to about 215 sq.ft (20㎡). Its 4-in-1 design combines cooling, dehumidifying, fan, and sleep modes, providing flexibility to use it year-round. The unit runs quietly at about 49 dB, making it a good choice for bedrooms or offices where noise can be distracting.

It’s energy efficient with a 3-star rating and uses an eco-friendly refrigerant, helping to keep electricity costs and environmental impact low. Moving it around is fairly easy thanks to built-in handles and smooth rolling casters, although it weighs around 22 kg, so some effort is needed to lift it if stairs are involved. Installation is simple with the included window kit that fits various window types without tools.

The digital display and remote control make adjusting settings straightforward, with added safety via a child lock feature. This model is a solid option for anyone needing a quiet, energy-conscious portable AC for smaller rooms, with handy features that make it easy to use and maintain. It is designed for rooms no larger than 215 sq.ft, so it may not efficiently cool bigger spaces, and while the noise level is low, it might still be noticeable if near-silent operation is preferred.

The De'Longhi Pinguino PACEL98 is a solid choice if you need a portable air conditioner for rooms up to about 100 cubic meters. Its 10,700 BTU cooling power is quite effective for medium-sized spaces, making it suitable for most living rooms or bedrooms. It stands out with its A-class energy efficiency, which means it uses less electricity compared to less efficient models, potentially saving you money on your energy bills. The built-in Eco Real Feel technology adjusts temperature and humidity automatically, adding comfort and energy savings.

In terms of noise, it operates at up to 64 dB, which is moderate—noticeable but not overly loud, similar to a conversation at home. The unit is designed with usability in mind, featuring remote control, touch controls, and wheels with handles, so moving it around shouldn't be difficult despite its weight of 33 kg. It includes a window kit for venting hot air outside, which is essential for portable ACs. A helpful bonus is the 3-in-1 functionality: besides cooling, it can dehumidify (removing up to 36 liters of moisture per day) and act as a regular fan. This makes it versatile, especially in humid climates.

Its size and weight mean it’s portable but not ultra-lightweight, so frequent moving between rooms might be a bit cumbersome. The noise level when running at full power might be distracting in very quiet environments like bedrooms at night. Also, installation requires a window for the exhaust hose, so it may not fit all room types. This De'Longhi portable AC balances strong cooling, energy efficiency, and multi-functionality, making it a good option for those who want a practical and relatively quiet portable unit that also helps with humidity control.

The De'Longhi Pinguino PACN82 Eco is a compact portable air conditioner designed to cool spaces up to about 80 cubic meters, offering 9,400 BTU of cooling power. Its energy efficiency is rated as class A, which means it uses power reasonably well and helps keep electricity costs down compared to less efficient models. It also uses an eco-friendly refrigerant (propane R290), which is better for the environment than common alternatives.

In terms of noise, it operates at around 52 decibels, similar to a quiet conversation, so it won't be too disruptive in most rooms. The unit includes a dehumidifier function to reduce moisture, which can make a room feel cooler and more comfortable. The 3-speed fan lets you balance between stronger cooling or quieter operation, and the remote control plus electronic timer make it easy to use. The size is relatively manageable, though at 30 kg it’s a bit heavy to move frequently, so it's best suited for situations where you don’t plan to relocate it often. Like most portable ACs, it requires venting through a window or door to expel hot air, which is important to set up correctly for effective cooling.

Its SEER rating of 2.4 and a 1-star BEE rating indicate that while it’s energy efficient within its class, it’s not the top performer available. The cooling capacity (2.4 kW) is moderate, making it more suitable for medium-sized rooms rather than very large spaces. For those looking for a portable unit that balances decent cooling, good energy use, and environmental care with useful features like dehumidification and remote control, the De'Longhi Pinguino PACN82 Eco represents a solid option, although it may not cool very large rooms as quickly as more powerful models.
