“Oh, this is different” – The First Words of Users Wearing Chill Hold at OSOTO FESTIVAL
When introducing the new neck cooler, “Chill Hold,” PowerArQ prioritized direct user experience over technical specifications. The brand emphasizes how the body feels when using their products, leading to a strategy of letting people try the device firsthand.
PowerArQ brought Chill Hold to the outdoor festival “OSOTO FESTIVAL vol.2” to gather immediate feedback from attendees. The festival environment, characterized by strong sunlight and heat, provided an ideal setting to test the device’s effectiveness.
Users were simply asked to wear Chill Hold without lengthy explanations. The immediate reactions upon the cooling plates touching their necks were notable, especially among individuals sensitive to heat. Many expressed surprise with phrases like “Oh, it’s cold” as soon as the device was activated, indicating a direct physical response before any detailed explanation.

The design of Chill Hold is engineered to deliver this immediate sensation. It features three Peltier devices strategically placed in the fixed belt to cool both sides of the neck and the nape simultaneously. This targets areas with major blood vessels to efficiently lower the perceived body temperature, prioritizing a comprehensive cooling sensation over mere numerical temperature readings.
The surface temperature of the cooling plates can reach approximately 2-3℃, which is notably lower than many competing products that typically cool to around 6-7℃. This 3-4℃ difference contributes to the immediate “Oh, this is different” reaction from users. Additionally, Chill Hold operates quietly with an exhaust fan rotation sound of 46.8dB, compared to 53.1dB for many other devices, aiming for a comfortable experience that doesn’t disrupt conversations or music in outdoor settings.
Chill Hold also incorporates a “Fluctuation Mode” that cycles between 10 minutes of operation and 2 minutes of pause. This feature helps prevent the skin from becoming accustomed to a constant cold temperature, ensuring sustained cooling sensation during prolonged use, such as at outdoor festivals. The device is secured with a double-lock mechanism of Velcro and buttons, ensuring it stays in place even during movement. Furthermore, Chill Hold offers 2-way functionality, serving as a neck cooler in summer and an electric neck warmer in winter.
The feedback gathered at OSOTO FESTIVAL vol.2 served as a crucial validation for PowerArQ, confirming that the product’s performance aligns with the intended user experience. The brand remains committed to developing tools that offer an immediate and noticeable benefit upon use.
