Sanko Releases “Sanko Official Limited Neck Cooler” Featuring W-Cooling for Optimal Summer Comfort

Wearables

Advanced W-Cooling System for Superior Comfort

This neck cooler is equipped with a “W-cooling” system that integrates a cooling plate, which directly cools the neck, and a powerful fan that delivers a comfortable breeze from the back of the neck. The cooling plate utilizes the Peltier effect, similar to small refrigerators, ensuring continuous coldness. The large-volume fan enhances the cooling effect through evaporative cooling, providing immediate relief to the often sweaty neck area.

The cooling plate provides a direct, refreshing sensation, similar to a cold can. This innovative cooling method offers a new level of comfort.

Versatile Cooling Modes

The device features three modes: Strong, Weak, and a unique “Sway Mode.” The Sway Mode automatically alternates between strong and weak cooling, designed to maintain a continuous sensation of coldness. This proprietary mode helps users feel cooler for longer durations.

Modes explanation

Portability and Extended Use

Being battery-operated, the neck cooler offers cable-free convenience. It can operate for up to 1.5 hours using the included fan battery in weak mode. For extended use, connecting a separate 10,000mAh mobile battery (sold separately) allows for up to 4.5 hours of continuous operation in weak mode, making it suitable for prolonged outdoor activities.

Battery usage explanation

For those seeking longer battery life, Sanko also offers a Phosphate Iron Mobile Battery (10,000mAh) with high safety and longevity.
