20,000mAh Battery | PD30W Fast Charging | 5 Turbo Speeds | IP66 Waterproof | Smart Display | Detachable Pack | Hands‑Free & Lightweight
The CoolSmith Waist Fan redefines portable personal cooling by integrating a high-performance fan with a substantial 20000mAh power bank into a single wearable device. The IP66-rated enclosure withstands water, dust, and tough conditions — from construction sites and farms to mountain trails and fishing trips. A built-in TEC semiconductor cooling module amplifies the cooling effect, while five selectable wind speeds provide precise control from a gentle 11.5 m/s energy-saving mode up to a powerful 16.5 m/s for extreme heat. The Type-C PD30W port enables two-way fast charging: recharge the device in approximately 2.5 hours, or use it to power phones, tablets, and other gadgets on the go. Its detachable modular architecture lets users swap battery packs, mix and match components, and replace parts individually — extending the product lifespan and reducing waste. Smart safety features including overheat, short-circuit, and overcurrent protection ensure reliable operation. With up to 15 hours of runtime on a single charge and a quiet ≤48dB noise level at close range, the CoolSmith delivers sustained, unobtrusive cooling that keeps both hands free for the task at hand.
