  • Key Specs
    • Recommended Room Size: 350 square feet (The recommended area size in which the product is designed to operate and produce optimal results, such as the desired heating or cooling. Generally, running a unit too big or too small for the space will result in ineffective operation and wasted energy.)
    • DOE SACC Cooling Power: 8000 british thermal units (The Seasonally Adjusted Cooling Capacity (SACC), implemented by the Department of Energy (DOE) after 2017, is a rating of a portable AC unit's cooling power. This rating is based on revised testing that more accurately measures a portable unit's performance, taking into account that these units do not vent heat in the same way as wall or window units and therefore were not cooling as effectively as the previous BTU ratings indicated (based on the ASHRAE-128 standard prior to 2017). Generally, the new cooling power ratings are lower than previous BTU ratings and can more reasonably be compared to the cooling capacities of other types of AC units.)

    • Number of Fan Speeds: 2
    • Airflow Rate: 275 cubic feet per minute
    • Remote Control: true
    • Integrated Heater: false
    • Sleep Mode: false (Enabling this mode sets the unit to first reach the desired temperature, then gradually increase the temperature over a period of time until it reaches a new set temperature, typically several degrees higher than the initial cool setting. This mode helps save energy while keeping the room comfortable.)
    • Timer: true
    • Auto Shut-Off: false (Feature automatically turns off the product.)
    • Window Venting Kit: true (Indicates whether supplies for venting the unit through a window are included.)
    • Energy Efficiency Ratio: 7.5 (The ratio of output BTUs (British Thermal Units) to input electrical energy (watts) at a given operating point. Generally, the higher the number, the more efficient the unit. Though higher efficiency units are typically more expensive upfront, they may offset the price in energy costs over time.)
    • Combined Energy Efficiency Ratio (CEER): 7.2 (The standard used to measure energy efficiency in window and room air conditioners by the Department of Energy (DOE) as of June of 2014. CEER measures the ratio of output BTUs (British Thermal Units) to input electrical energy (watts) in standby mode and while the unit is operating. Generally, the higher the number, the more efficient the unit. Though higher efficiency units are typically more expensive upfront, they may offset the price in energy costs over time.)

  • Rated 4 out of 5 stars

    Powerful ac with incredible but leaks way too much

    I would've given this ac 5 star if it didn't leak so much! the ac leaves my floor wet! I had to order a drain hose (since it didn't come with one) the drain hose works out. It doesn't secure properly so water still gets the the floor at times. This is highly disappointing because I've had a used portable lg ac for over 3-4 years and it didn't leak as much as my new portable lg ac leaks! I will have to return it and just stick with the window ac. Other than the leak the ac does an amazon job at cooling down the room. It cools it down much better than window ac or other ac brands, which Is why I bought this specific ac in the first place. I've attached pic of the ac and the drain/bucket. if I didn't have the drain/bucket my room would be flooded.

    Not impressed

    This is a nice looking sleek unit, and i like LG products. However im not impressed with the cooling ability of this particular unit. Picked this up to temporarily cool my RV while my rooftop unit is being replaced. It barely cooled my living area which is 12x14, forget about getting any cool air up in the bedroom.
