Our Verdict
SereneLife SLPAC8
Black+Decker BPACT12HWT
The Black+Decker BPACT12HWT is a better portable A/C unit than the SereneLife SLPAC8 for the most part. The Black+Decker offers significantly more cooling capacity in a roughly similarly-sized package, all the while producing less noise. The SereneLife's lower capacity can work to its advantage in oversized spaces, in the sense that its compressor being forced to work constantly will minimize swings in humidity and temperature. However, this also increases energy requirements and places more wear and tear on the unit.
