The Costway 3-in-1 9000 BTU portable air conditioner brings app convenience to dependable mid-room cooling, with WiFi control via the Smart Life app so you can start, stop and adjust it from your phone, plus an LED display and remote for hands-on control. With 9000 BTU it cools rooms around 20m², suiting bedrooms, home offices and dorms, and three modes (cool, dry and fan) keep it useful beyond the hottest weeks. Its dehumidifier is a strong 42 L/day, well placed to tackle damp and humidity. Quiet at 52 dB, it's comfortable for bedroom and study use, and a sleep mode keeps nights settled. Rated at 1010W in cooling, it costs roughly 26p an hour at 26p/kWh, with a 24-hour timer to schedule operation and trim costs. As a single-hose monobloc it must be vented through a window using the supplied exhaust hose and window kit, so it isn't a hoseless unit; a drain hose is included. Adjustable temperature and airflow direction add flexibility. Four rolling wheels and two handles make the 23.5kg body easy to move wherever you need it. The box includes the AC, exhaust hose, hose connector, adapter, window kit, drain hose, remote control and instruction manual.
