How to choose
Read BTU with its standard
Portable air conditioner BTU comes in two standards here: ASHRAE and DOE, also called SACC. The SereneLife lists 12,000 BTU (ASHRAE), the DREO lists 10,000 BTU (DOE), the BLACK+DECKER lists 5,000 BTU (SACC), and the LG lists 10,000 BTU (DOE) with 14,000 BTU (ASHRAE). Compare figures only within the same standard, since the two standards measure differently.
Hoses and drainage
Hose count matters: the SereneLife and DREO use dual-hose systems, while the BLACK+DECKER uses a single hose. For drainage, the DREO self-evaporates excess water automatically in environments under 90% humidity, while the SereneLife window kit includes a drain pipe. Check the hose setup and drainage against your window and room before you buy.
Controls and noise
Control options differ: the SereneLife, DREO and LG offer app control with a remote, while the BLACK+DECKER uses a full function remote. Noise also differs: the DREO lists 42 dB, the SereneLife lists 49 dB, and the BLACK+DECKER lists 52 dB. Compare the noise figure against how quiet the room needs to be.
