Features:
The ZERA mini is a credit-card-sized personal cooling fan weighing just 69 grams, delivering a jetstream up to 13 m/s with a range of 10 meters from a 30,000 RPM brushless motor. Its surface dimensions match a standard credit card, fitting into coin pockets, micro-bags, or the palm of a hand alongside everyday essentials like keys and earbuds. A digital display offers 100-level wind speed control with single-click quarter-step presets and press-and-hold fine adjustment. The rechargeable battery provides up to 10 hours of runtime on a single charge via USB-C. A 360° easy-switch clip, neck and wrist strap system, and carabiner enable hands-free wear on shirts, caps, backpacks, or as a necklace, directing airflow exactly where needed. Beyond personal cooling, the concentrated airstream serves as a portable blower for dusting electronics, clearing workspaces, or assisting fire-starting.
