Sanko Co., Ltd. (Location: Chiyoda-ku, Tokyo, Representative Director: Taichi Arai) launched the "Sanko Official Limited Neck Cooler" on June 10th, which focuses on popular fan batteries and achieves an overwhelming cost performance of ¥4,980. It will be sold in limited quantities on the official Sanko online store and various e-commerce sites. This product is a neck cooler equipped with a "W Cooling" system that combines a cooling plate to directly cool the neck and a high-volume fan to send comfortable airflow from behind the neck. The cooling plate uses the Peltier system, the same as that used in small refrigerators, to maintain a continuous cool sensation through electrical power. Furthermore, the high-volume fan utilizes evaporative cooling to quickly cool the neck area, which tends to sweat easily. In addition to strong and weak modes, it features three types of modes, including its unique "Fluctuation Mode" that sustains the sensation of coldness. As it is battery-powered, it can be used cable-free. Moreover, when connected to a 10,000mAh mobile battery (sold separately), it can be used for extended periods of up to 4.5 hours. With adjustable arm length and angle, it comfortably fits neck circumferences from approximately 37 to 50 cm. It is recommended for those who want to stay comfortable even in the summer heat or want an easy way to cope with the heat. ● Focusing on the popular "Fan Battery" based on user feedback This product was born from the "Kuradashi Project," which revives unopened items of popular hit models exclusively for the official online store. For its re-release, the included items were narrowed down to only the "fan battery," which received strong support from users, optimizing it to directly experience the product's powerful cooling performance. By simplifying the configuration, we have achieved overwhelming cost performance at ¥4,980 (tax included). We deliver this as an official online store-exclusive model with gratitude to Sanko fans for the upcoming full-scale summer. ■ Wearable cooler worn around the neck ■ Adopts Peltier cooling method, same as small refrigerators ■ Equipped with a fan ■ Plate temperature is up to approximately -10 degrees Celsius lower than ambient temperature ■ Strong and weak 2-level switching ■ Fluctuation mode that automatically repeats strong and weak ■ Rechargeable, usable cable-free ■ Can also be used with your existing mobile battery ■ Size adjustable for a perfect fit for both women and men ■ Lightweight, approximately 250g ・Size / Minimum: Width 130 x Height 120 x Depth 80 (mm) 　　　　Maximum: Width 160 x Height 120 x Depth 160 (mm) ・Weight / Main unit: Approx. 135g 　　　　Fan battery: Approx. 115g ・Accessories / Main unit, fan battery, USB Type-C cable, Japanese instruction manual ・Neck circumference size / Minimum: Approx. 37cm, Maximum: Approx. 50cm ・Power supply / Fan battery (3.7V / 2600mAh / Lithium-ion) ・Modes / Strong mode / Weak mode / Fluctuation mode ・Cooling plate temperature estimate / Strong mode: -10 to -8°C from ambient temperature 　　　　　　　　　　　　Weak mode: -7 to -4°C from ambient temperature 　　　　　　　　　　　　*Measured at an ambient temperature of 35°C.
