【17,000 BTU Portable AC for Large Rooms Up to 850 Sq. Ft.】Built for large living rooms, bedrooms, apartments, open-plan spaces, and home offices, this 16,000 BTU portable air conditioner delivers fast, steady cooling for spaces from 550 to 850 sq. ft. The high-efficiency compressor helps cool the room quickly, while the adjustable 61°F–90°F temperature range lets you set the comfort level that fits your space.

【Smart App, Remote & LED Touch Control】Control your portable AC from the top LED touch panel, included remote, or Smart Life app. The full-function remote works from up to 23 ft away, so you can adjust temperature, fan speed, operating mode, and the 24-hour timer from across the room or before you arrive home. The app also lets you customize your sleep curve for more personalized comfort.

【Quiet Cooling with Sleep Mode】Designed for bedrooms, home offices, and nighttime comfort, this portable air conditioner operates as low as 45dB. Sleep Mode gradually adjusts airflow and compressor activity as the room cools, helping maintain a comfortable temperature with less noise, fewer cold drafts, and fewer overnight temperature swings.

【4-in-1 Comfort with 120 Pints/Day Dehumidification】More than a room air conditioner, this unit combines cooling, dehumidifying, fan, and sleep functions for year-round comfort. It removes up to 120 pints of moisture per day to help reduce sticky, humid air, while the 3-speed fan and 35°–80° wide-angle auto-swing help circulate cool, comfortable airflow more evenly throughout the room.

【Self-Evaporating Cooling with Less Manual Draining】The advanced self-evaporating system recycles and evaporates excess moisture during operation, helping reduce the need for manual draining. In humidity levels below 90%, the unit supports up to 72 hours of drainage-free cooling for more continuous comfort. A drain hose is included for extremely humid conditions.

【Easy Setup, Portable Design & U.S. Phone Support】The full window installation kit fits most sliding windows, while side handles and smooth 360° caster wheels make room-to-room movement easy. Built-in child lock adds extra safety for family use. Includes 1-year overall unit protection, a 3-year compressor warranty, and U.S.-based phone support for direct after-sales assistance.
