Earnmore 500 ml Air Cooler: what works, what doesn't?
What works well
- Cordless via battery: the 1,800 mAh battery provides up to 6 hours of mains-independent cooling after a full charge, flexible to use anywhere
- Ultrasonic humidifying: fine spray mist cools and humidifies at the same time, helping against dry skin and nose in hot, dry rooms
- Ice water boost: ice water in the 500 ml tank increases the cooling effect for noticeable cooling
- Quiet operation: designed for quiet night operation, without compressor, CFC-free, good for the bedroom
Points of criticism
- Personal cooling only: like all evaporative coolers it lowers only the perceived temperature in the airflow, not the room temperature
- Small 500 ml tank: lasts only 3 to 6 hours, so frequent refilling is needed for longer operation
- Only 2 levels: less fine adjustment than devices with three fan and mist levels

Build quality & everyday use
What carries the Earnmore 500 ml Air Cooler in everyday use: cordless via battery (the 1,800 mAh battery provides up to 6 hours of mains-independent cooling after a full charge, flexible to use anywhere) and ultrasonic humidifying (fine spray mist cools and humidifies at the same time, helping against dry skin and nose in hot, dry rooms). We have to be honest about the weaknesses: personal cooling only, as like all evaporative coolers it lowers only the perceived temperature in the airflow, not the room temperature.
If you set the device up to save space, allow ventilation clearance of at least 5 cm at the sides and 10 cm at the rear, otherwise the compressor may overheat.
