Review on 🌬️ Stay Cool Anywhere: Portable Personal Air Cooler with Remote, 4000mAh Battery, Mini Air Cooler (Blue Deep) by Melissa Marie

Only about 4 square inches of the grille/airflow grille is mist cooled (see 2nd picture with blue box). The remaining 30 square inches of airflow space is at ambient temperature. Using ice water and maximum settings, I measured the temperature of the grille and a small cooler spot was about 10 degrees Fahrenheit colder than the surrounding area. In my low humidity environment, a 10 degree difference was expected. This small area wasn't enough to make a noticeable difference in overall comfort, even when my face was 2 inches from a cool spot. It's basically an expensive little portable fan.
