The verdict in 90 seconds
The BLACK+DECKER BPACT08WT is a legitimate answer to cooling one small room and a bad answer to almost anything larger. Its honest capacity is 5,300 BTU SACC, not the 9,000 BTU on the box, which puts it in the 150 to 250 sq. ft. bracket. Within that bracket owners are broadly happy: it is easy to set up, it moves on casters, and it costs less than most competitors. Outside it, the complaints are immediate and consistent. It is also loud, single-hose, and forgets its settings whenever the power flickers.
Best for a bedroom or home office of roughly 150 to 250 sq. ft. with no window AC option
- 9,000 BTU ASHRAE rating, 5,300 BTU SACC
- Three-in-one cooling, dehumidifying and fan modes
- Self-evaporating design with a bucketless system in most conditions
- Window kit, exhaust hose, remote and 24-hour timer included
Why buy it: it is the cheapest genuinely functional route to cooling one room in a house with no central air and windows a window unit will not fit.
What owners consistently praise
Setup that takes twenty minutes. The window bracket, exhaust hose and adaptor go together without tools, and the kit fits most single-hung and double-hung windows between roughly 22 and 47 inches wide. Owners with no DIY confidence repeatedly describe getting it running the day it arrived, which is the main advantage over a window unit that has to be lifted into a sash.
It genuinely cools a small room. In a bedroom or a home office, the consensus is that it drops the temperature by a useful margin and holds it. Owners in apartments with no central air and in rentals that prohibit window units are the most positive group in the record.
The dehumidifier mode. Used with a hose in the continuous drain port, it pulls a meaningful amount of moisture out of a basement or a damp room. Several owners bought it for cooling and describe the dehumidifier function as the reason they kept it.
Portability and the remote. Casters roll on hard floors, the unit is manageable for one person to reposition, and the remote plus 24-hour timer means you can set it to cool a bedroom before you go up.
What owners actually complain about
Noise. This is the top complaint by volume. Portable air conditioners put the compressor in the room with you, and this one is audibly a compressor. Owners describe it as tolerable as background noise for sleeping but disruptive for a video call or watching television at normal volume. It cycles on and off, so the change is what you notice.
The BTU expectation gap. The second-biggest source of one-star reviews is buyers who read 9,000 BTU and up to 400 sq. ft., put it in a living room, and found it could not keep up on a 95°F afternoon. The SACC number tells the truth and the listing buries it.
Single-hose losses. Blowing room air outdoors depressurises the space and pulls hot air in through every gap. Owners in leaky older houses report the unit running constantly without ever reaching setpoint, which is a design characteristic rather than a fault.
The exhaust hose is short and stiff. At roughly five feet fully extended, it constrains where the unit can sit, and the corrugated hose radiates heat back into the room. Wrapping it is a frequent owner modification.
Settings lost on power interruption. After an outage or a tripped breaker the unit reverts to its defaults instead of resuming. In areas with summer brownouts this is a real irritation, and it defeats most smart-plug scheduling.
Draining in humid climates. Self-evaporating is conditional. In the Southeast, owners report the reservoir filling and the unit shutting down overnight until drained.
Build and longevity. The casing is light plastic, the caster sockets and the window bracket draw complaints, and a persistent minority report cooling performance dropping off or the compressor failing in the second or third season. The one-year warranty is short for an appliance in this price range.
Who it suits, and who should buy something else
Buy it if you need to cool one room of 250 sq. ft. or less, a window unit is not permitted or will not fit, and you accept compressor noise.
Buy a window air conditioner instead if your window and your lease allow it. A window unit at the same price is quieter in the room, more efficient, and cools a larger space — the trade-offs are laid out in portable AC vs window AC.
Buy a dual-hose portable instead if the room is large, leaky or very hot. See single vs dual hose portable air conditioners for why the difference is not marketing.
Buy a larger portable instead if your room is over 300 sq. ft. — size it properly with what size portable air conditioner do I need, and compare the field in our best portable air conditioner guide or the bedroom-specific best portable AC for a bedroom.

The bottom line
Sized honestly, this is a reasonable budget appliance that solves a real problem for apartment dwellers and anyone whose windows will not take a conventional unit. Sized by the number on the box, it is a disappointment waiting to happen. Work from the 5,300 BTU SACC figure, keep it in a room under about 250 sq. ft., seal the window kit properly, and expect to hear it running.
