18000 BTU Portable Air Conditioner 4-in-1 with Remote Control

The Costway 18000 BTU 4-in-1 portable air conditioner is the heavyweight of the range, built for large UK rooms up to 50m² where smaller portables simply can't keep up, such as open-plan living areas, big offices and studios. With 18,000 BTU and a strong 550 m³/h airflow, plus a 74° auto swing, it pushes cool air across a wide space rather than chilling just one corner. Four modes (fan, cool, dry and sleep) cover the year, and the dehumidifier is exceptional at 120 L/day, enough to transform a damp large room. Power is substantial at 1949W cooling, so expect around 51p an hour at 26p/kWh, the trade-off for cooling a big space. At ≤65 dB on full it's audible, as expected for this capacity, with a smart sleep mode and 1-24 hour timer to ease nights and limit running time. 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. Control is via the LED touch panel or remote. At 37kg it's heavy but on wheels. The box includes the AC, exhaust hose, hose connector, adapter, window kit, drain hose, remote and manual.
