This portable air conditioner is the SMART choice for versatile cooling! Cool your home from anywhere using LG ThinQ technology to control your air conditioner with your phone or with Amazon Alexa and Hey Google to have control with the sound of your voice. This quiet portable air conditioner is ideal for cooling medium-sized rooms up to 450 sq. ft. You can even add a bit of warmth on cooler days with the supplemental heat option. The portable AC provides consistent cooling round the clock with a 24-hour timer and helps improve ventilation and air flow with multiple cooling and fan speeds. It has a built-in dehumidifier, and its auto-swing air vent helps direct the flow of air where it's needed most, whether cooling, dehumidifying or just circulating air. If there is a power outage, the auto restart feature will automatically turn your unit back on when power is restored. It's also easy to maneuver with easy-rolling casters you can use to efficiently move the unit to another location.
