Black+Decker BXAC40006GB 9000 BTU Portable Air Conditioner review
Cooling a single bedroom or home office through a summer heatwave.
By Tom Calder · Updated 24 July 2026 · Price checked against our tracker
A competent, well-supported 9,000 BTU portable unit from a familiar brand, doing cooling, dehumidifying and fan duties in one box. It is a sensible mid-range choice for a small-to-medium room, provided you can vent the hose out of a window.
Approximate typical UK street price as of July 2026, based on listings at PriceRunner (from ~£348), Electricshop and other UK retailers; commonly sits in the £330-£380 range depending on season and stock.

- Established brand with a 2-year guarantee (1 year extendable on registration)
- Genuine 3-in-1: air conditioning, dehumidifier and fan modes, with a 24-hour timer and remote
- Efficient R290 refrigerant and Class A rating for its category, on castor wheels for easy moving
- Noisy at full speed (around 65 dB), which many find intrusive overnight
- Single-hose design must be vented through a window and is thirsty to run, so it is not cheap in a long heatwave
