9000 BTU 4-in-1 Portable Air Conditioner with App Control and Sleep Mode

The Costway 9000 BTU 4-in-1 portable air conditioner is a true all-seasons unit, combining cooling, heating, dehumidifying and a fan in one body with WiFi app control. With 9000 BTU cooling and 7000 BTU heating it warms or cools rooms up to 20m² quickly and evenly, so it works in a cold snap as readily as a heatwave. The Smart Life app lets you run it from anywhere, alongside the remote and LED touch panel. Its 42 L/day dehumidifier is one of the strongest here for tackling damp, and manual swing louvres help spread air around the room. Quiet at 52 dB, it's comfortable for bedroom use. Rated at 1010W in cooling (850W heating), it costs roughly 26p an hour cooling at 26p/kWh. 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. Two fan speeds, a 16-32°C range and a 24-hour timer give plenty of control and help keep energy use down. At 24kg it moves between rooms. The box includes the AC, exhaust hose, hose connector, adapter, window kit, drain hose, remote control and instruction manual.
