BUSAN, South Korea - August 24, 2026 - As temperatures continue to rise worldwide, demand for practical personal cooling solutions is increasing. The second-generation COOLSMILE, now available on Kickstarter, introduces a different approach to portable cooling by freezing the entire cooling body instead of only a small cooling core. This innovative design delivers colder air and longer-lasting cooling without the need to cool an entire room.
Up to Approximately 17°C (30.6°F) Difference Between Ambient and Outlet Air Temperatures in a 30°C (86°F) Test Environment.
*The air temperature near the outlet was measured under controlled test conditions at an ambient temperature of 30°C (86°F). The values shown in the graph represent the difference between the ambient temperature and the air temperature at the outlet. They do not mean that COOLSMILE lowers the temperature of an entire room by 17°C. Actual performance may vary depending on ambient temperature, freezing time, measurement location, fan setting, operating environment, and other factors.
Key Features
・Freeze the Entire Cooler
The entire cooling body functions as a thermal storage system.
・CoolShot™
The included flexible hose directs cooled air precisely where it is needed, including the face, neck, bedside, or pet area.
・Dust Filter System™
A replaceable air-intake filter helps reduce the entry of dust, pollen, pet hair, and other unwanted particles.
・Portable Operation
Once charged, the USB-C rechargeable fan operates without an external power connection.
Targeted Comfort, Indoors or Outdoors
COOLSMILE is designed to deliver focused cooled air to the person or area that needs it, rather than cooling an entire room. Its portable design makes it suitable for camping, car camping, outdoor events, garages, desks, bedsides, pet areas, and more.
Product Overview
The following images highlight the design, cooling structure, and key specifications of the second-generation COOLSMILE.
・Cooling Performance: Under controlled test conditions at an ambient temperature of 30°C (86°F), COOLSMILE recorded a temperature difference of up to approximately 17°C (30.6°F) between the ambient air and the air at the outlet.
・Cooling Duration: Under controlled test conditions, the air temperature at the outlet remained approximately 3°C (5.4°F) below the ambient temperature about three hours after operation began. Cooling duration was recorded at up to approximately twice that of the previous COOLSMILE.*
*Results were obtained under controlled test conditions conducted by COOLSMILE. Actual performance may vary depending on ambient temperature, freezing conditions, measurement location, fan setting, operating environment, and other factors.
・Power: USB-C rechargeable fan. No connection to an external power source is required during operation when the fan has been charged in advance.
