[2025 Summer Upgraded Version with Four Cooling Plates and Peltier Cooling Vest] Equipped with an industry-leading semiconductor cooling system, this vest has evolved from conventional compact coolers to include four large cooling plates on the front and back! With a simple one-button operation, it instantly cools your skin, like holding a cold can of juice against your back, for a super refreshing feeling! It delivers cooling to your skin in just one second, reducing the perceived temperature by up to -28°C—Japan's first and most powerful Peltier vest! This summer's new product is a must-have for anyone battling the heat. It's perfect for on-site workers, as well as those who work in kitchens and factories, where heat is a constant challenge. We're confident in recommending it because it keeps you cool all day long! [Equipped with Peltier elements, fast cooling, and up to -28°C] Utilizing the characteristics of Peltier elements, also found in small refrigerators, this device delivers an electronic cooling effect that instantly cools your entire body, from your back down. Just turn it on and within 10 seconds, it delivers high-level cooling performance, reaching temperatures up to approximately -28°C below ambient temperature. The aluminum block dissipates heat, physically cooling your back and preventing overheating, freeing you from the sweltering heat! It can also be worn under fan-equipped workwear. The Peltier cooling plate absorbs heat through the metal surface, not through wind, so your clothes won't bulge and get in the way of your work. Perfect for preventing heatstroke in the summer! [30,000mAh Large Capacity, Strong and Weak Modes, and Long Continuous Operation] Powered by USB, simply connect it to a 5V 3A mobile phone and press and hold the power button for instant cooling! It comes with a 30,000mAh lithium battery for extended operation. Strong mode: Cools to temperatures up to -28°C below ambient temperature, with a runtime of approximately 5-6 hours. Weak mode: Cools to temperatures up to -22°C below ambient temperature, with a runtime of approximately 7-8 hours. (These runtimes were measured using a 30,000mAh mobile phone.) In summer, it's suitable for electricians, construction workers, welders, factories, couriers, cooks, traffic police, agriculture, fishing, and more. (Note: Usage times are approximate and may vary depending on wear conditions, usage environment, and number of charges.) [Compatible with Air-Conditioned Workwear & 5V 3A Output] The new 2025 Peltier Vest can be used with air-conditioned workwear as a cooling inner layer. It pairs perfectly with air-conditioned workwear and cooling vests! Combining them doubles the overall effect! No dedicated device is required; simply connect it to a standard mobile device with an output of 5V 3A or higher and it will function normally. This "wearable air conditioner" will further reduce fatigue during the heatwaves, helping you get through the summer without a doubt! Lightweight, Compact, and Quiet Design: The compact, lightweight design minimizes strain on the body and ensures comfortable use. Its back-hanging design frees up your hands, allowing you to concentrate on work or study while enjoying the ultra-cooling sensation. It also features a Japanese-made DC silent motor that reduces operating noise to just 30dB, making it quieter than air-conditioned clothing. It provides outstanding cooling performance regardless of the temperature, even in the heat of summer, and its comfortable cooling sensation prevents heatstroke and improves work efficiency.
