While the summer offers numerous ways to beat the heat outdoors, cooling down the temperature indoors usually means turning on the air conditioner.
In a house, apartment or office without central air conditioning, an electric fan can provide some relief. However, a portable air conditioner is much more effective in creating a comfortable space. They are easy to move from room to room, you can set them up wherever the cooling is needed most, and they don't block light from windows like the window-mounted units do. They can even supplement cooling in areas a central air conditioner can't reach.
LG and De'Longhi offer some of the best portable air conditioners on the market, but which brand is better?
LG Electronics Inc. is a South Korean multinational electronics company that manufactures home appliances, including washing machines, tumble dryers, refrigerators, microwave ovens, vacuum cleaners and air conditioners.
The company offers portable air conditioners with Btu ratings suitable for cooling spaces from 200 to 700 square feet at prices from $340 to $700. Many of its units support the company's ThinQ technology. The app lets you monitor and control your device from virtually anywhere. And for hands-free operation, you can activate the air conditioner with the sound of your voice using Google Assistant on devices such as Google Home, Nest and Amazon Echo.
What you need to know: This 10,000 Btu smart portable air conditioner cools large rooms up to 500 square feet, operates at a quiet 44 decibels and saves up to 40% in energy costs.
What you'll love: LG ThinQ technology lets you set your air conditioner from anywhere using your smartphone, and voice control works with Amazon Alexa and Hey Google. You can create your own cooling schedule with the 24-hour timer and three cooling and fan speeds.
What you should consider: Some buyers report the unit was noisier than advertised, and it generates a faint mildew odor if the drain tank is not emptied properly.
What you need to know: For the budget-minded buyer, this 8,000 Btu portable air conditioner cools medium-size rooms up to 350 square feet and includes a 24-hour timer for creating a cooling schedule.

What you should consider: Buyers report the remote control needs a longer range for effective use. The stiff hose lacks insulation, letting heat radiate back into the room.
What you need to know: This 6,000 Btu portable air conditioner is ideal for cooling, dehumidifying or operating in the fan-only mode for smaller rooms, up to 250 square feet.
What you'll love: The oscillating air vent circulates air evenly throughout the room using two cooling and two fan speeds. The unit comes with a window-vent installation kit, an LCD Remote control and a check filter alert that warns when it's time to clean the filter.
What you should consider: Some buyers say this air conditioner is noisy, and the exhaust tube remains hot.
De'Longhi is a manufacturer of small appliances based in Treviso, Italy, perhaps best known for its high-quality espresso machines. The company also produces gelato makers and Pinguino portable air conditioners.
De'Longhi offers basic portable air conditioners equipped with features including LCD control panels, timer setting functions and a single hose configuration. At the top end, the company produces the Pinguino Care4Me, which is fitted with Wi-Fi connectivity and an artificial-intelligence-supported thermostat to sense the room temperature and adjust accordingly.
De'Longhi offers portable air conditioners designed for cooling rooms from 400 to 700 square feet at prices from $375$ to 750.
What you need to know: This 14,000 Btu portable air conditioner offers powerful cooling for larger rooms up to 700 square feet with a whisper-quiet sound that lets you sleep while staying refreshed.
What you'll love: The three-in-one cooling, dehumidifying and fan settings includes UV-C technology, which protects against viruses by eliminating 99.5% of dust particles from the air. The auto-evaporating system recycles residual moisture by expelling it through the exhaust hose, reducing the need to drain excess moisture manually.
What you should consider: The simple remote control does not illuminate, making it difficult to see the buttons in low light.

Both LG and De'Longhi produce excellent portable air conditioners. LG is backed by a massive electronics company and offers units with similar basic features to the De'Longhi models at a slightly lower price. But De'Longhi units are at the forefront of portable air conditioner innovation with quiet operation, an artificial intelligence feature and reduced environmental impact.
For the buyer willing to spend a few bucks more, De'Longhi is the better choice.
