7000 BTU Portable Air Conditioner 4 in 1 Cooling Unit

The Costway 7000 BTU portable air conditioner is a compact 4-in-1 cooling unit sized for smaller UK rooms – think home offices, box rooms and bedrooms. At roughly 600 BTU per square metre, 7000 BTU comfortably covers spaces up to around 12 m², so it's well matched to a single bedroom rather than an open-plan lounge. As a genuine refrigerated air conditioner it actually lowers the room temperature, unlike a fan or evaporative cooler, and its four functions in one mobile cabinet give you flexible comfort year-round. Being honest about how portable air conditioners work: this is a single-hose unit that must be vented through a window using the exhaust hose – there is no such thing as a truly hoseless portable air conditioner, as the heat extracted from the room has to go somewhere outside. Running cost depends on the cooling power drawn, but as a guide a unit of this size typically costs in the region of 18–25p per hour at around 26p per kWh. The compact, wheeled-style portable design means you can move it between rooms as the day's heat shifts. For affordable, genuine cooling in a small room, this 7000 BTU 4-in-1 is a sensible entry point.
