"COCOHIE R8" is a portable cooling fan that can be carried anywhere. With a simple operation of filling the water tank and pressing a switch, it pinpoint-cools just your immediate surroundings. Utilizing "Hydro-chill Technology," a cooling technology that uses the phenomenon of vaporization heat, it releases cold air up to -10°C (compared to room temperature) *1 from the air outlet. Since it can also run on a mobile battery *2, it is highly useful not only indoors but also in places without electrical outlets and outdoors. It can also be used in outdoor scenes such as camping.

The electricity cost, which is a common concern, is wallet-friendly at about 208 yen *6 even if left on for a whole month, making it designed for easy daily use.

"COCOHIE R8" has been favored by many customers as a summer problem-solving item for excessive cooling from air conditioners, heavy electricity bills, and adjusting different sensible temperature preferences among individuals, as well as a cooling appliance for places without air conditioners. It has achieved the No. 1 sales amount in the cooling fan market *3, and cumulative series sales have surpassed 2.7 million units *4. Since its initial launch in 2018, it has undergone annual renewals to make it even more convenient to use.

*5 Comparison of wind speed at the outlet with the previous model Cocohie R7. Researched by our company.
*6 Calculated at 31 yen per 1kWh when left on for 1 month (31 days) at a power consumption of 9W with air volume (Turbo) and no oscillation function. Varies depending on usage conditions.

[COCOHIE R8 Product Features]

(1) Cool - Cold air created by vaporization heat, evolved blowing performance
"COCOHIE R8" efficiently cools inhaled hot air using proprietary patented cooling technology utilizing the "vaporization heat phenomenon," where water absorbs surrounding heat as it evaporates. This coolness realizes cold air up to approximately -10°C (vs. room temperature) *1 at the outlet. Furthermore, the 2026 latest model adopts a high-performance motor, improving wind speed by about 30% *5 compared to the previous model. Delivering the air cooled by vaporization heat more powerfully has further enhanced the sensible coolness. Unlike fans that merely circulate air, the structure that cools with the power of water delivers a comfortable cool breeze even in the hot summer.

(Reference) Thermography comparison between "COCOHIE R8" and an electric fan

As a result of comparing the temperature of the palm after 5 minutes with thermography, COCOHIE R8 turns a lower-temperature blue, confirming that it is cooler. Unlike fans that circulate air, it delivers a comfortable cool breeze even in hot summers with the power of vaporization heat.

*Test conditions: Room temperature 30°C, humidity 60%, 30cm from outlet, measuring palm surface temperature after 5 minutes / Varies depending on test and usage conditions. Compared with an electric fan close to the 9W power consumption of Cocohie's air volume (Turbo) and no oscillation operation. The temperature range of the thermography was uniformly set to 31°C to 37°C for measurement.

(2) Portable - Desk size suitable for both indoors and outdoors

Lightweight and compact design at approximately 1.5kg. Comes with a handle, making it convenient to carry around.
