Black+Decker 14,000 BTU Portable Air Conditioner (BPACT14WT)

Best for: Bedrooms and home offices under 300 sq ft.
Our recommendation
Match the unit to the room: Black+Decker for living rooms up to 350 sq ft, SereneLife for bedrooms. The Black+Decker's 8,000 BTU SACC output handles larger spaces; the SereneLife's 10,000 BTU ASHRAE chassis is lighter, more compact, and better behaved in a small room where an oversized unit would short-cycle.
Output and room match
The Black+Decker delivers 8,000 BTU SACC for rooms up to 350 sq ft; the SereneLife's 10,000 BTU ASHRAE (roughly 6,500 SACC) suits rooms up to about 300 sq ft comfortably. Putting the Black+Decker in a small bedroom wastes energy on short-cycling; putting the SereneLife in a large living room leaves it running flat-out on the hottest days.
Size and maneuverability
The SereneLife is the lighter, more compact unit: easier to roll between rooms, easier to store for winter, less floor space surrendered. The Black+Decker is a full-size 14,000 BTU chassis. If the unit moves seasonally, size matters.
Features
The Black+Decker's follow-me remote is the meaningful feature edge, sensing temperature where you sit. The SereneLife counters with a clean digital touch panel and remote of its own, plus the same 3-in-1 mode set. Neither has the Whynter's dual hoses or the LG's inverter.

Questions, answered
Can the SereneLife handle a living room?
A small one. In a 300-plus sq ft living room with sun exposure, it will run continuously on the hottest days and may not hold your setpoint. That is the Black+Decker's job.
Which is better for a bedroom?
The SereneLife. Right-sized output means longer, quieter cycles and better dehumidification instead of the cold-and-clammy short-cycling an oversized unit produces.
