A test of over 30 portable air conditioners has been conducted to determine which ones can keep people coolest during a heat wave. Some outlets are reporting on where to find portable air conditioners and fans that are still in stock, while others are focusing on ranking and reviewing different products for the summer season. However, it appears that not all of the reported tests are related to portable air conditioners, with some outlets discussing other products such as moisturizers, lip balms, tower fans, guitar amps, infant car seats, and solar generators.
