LG LP0721WSR vs Black+Decker BPACT12HWT

Neither the LG LP0721WSR nor the Black+Decker BPACT12HWT are especially noteworthy A/C units, but if you're in need of a single-hose portable unit, they've each got their own strengths and weaknesses. The Black+Decker offers greater cooling capacity and will chill the air in a comparably sized room faster. That said, its compressor cycling will result in more noticeable swings in temperature and humidity compared to the LG. It also uses R410a as a refrigerant, which incurs a higher environmental footprint compared to R32, used by the LG and other newer A/C units.
