Aecooly has introduced the Cold Air Ultra, a handheld cooling device designed to move beyond the limitations of traditional portable fans. While standard fans merely redistribute ambient air, this device utilizes an active cooling system that combines a 70,000 RPM brushless motor with pneumatic atomization. By forcing air through a copper nozzle to create ultra-fine micro-particles, the device accelerates evaporation to lower skin temperatures by up to 18°F. Featuring a 7,000 mAh battery, a color touchscreen interface, and a metallic-inspired finish, the unit functions as both a high-performance personal cooler and a 20W power bank.
The device distinguishes itself through its engineering, specifically the use of a high-pressure pump that shears water into 20 μm particles. This process, known as pneumatic atomization, cools the air before it leaves the device, ensuring the output is genuinely chilled rather than simply humidified. The internal components are housed in a patented airtight structure that separates the water circuit from the electronics, ensuring safety and efficiency. Its compact, cylindrical design is intended to maintain high-pressure airflow, minimizing energy loss compared to conventional plastic-housed fans.
User control is managed via the “Little Droplet,” a front-mounted touchscreen that allows for 100-level speed adjustments and provides real-time data on battery and water levels. Beyond its cooling capabilities, the Cold Air Ultra offers practical utility for outdoor activities or commutes. The 7,000 mAh battery supports up to 10 hours of operation and includes Quick Charge and Power Delivery support, allowing it to charge other mobile devices. The system also features a magnetic accessory attachment, including specialized nozzles and a brush head, which can be swapped without the need for additional tools.
Recognized with a 2026 Red Dot Design Award, the Cold Air Ultra is available in black or blue finishes. For those seeking a more streamlined version of the technology, Aecooly also offers a standard model featuring a 4,500 mAh battery and five speed settings. The flagship Ultra model is positioned as a premium tool for personal climate control, combining advanced evaporative cooling with the versatility of a portable power supply.
