OpenBay N352 outdoor fan 100 speeds 11 hrs 20000 rpm 4.4 in .33 lb

Pocket-Sized Turbo Cooling

The OpenBay N352 is a handheld outdoor fan that fits in a pocket at 4.4 by 1.8 by 1.8 inches and weighs 0.33 pounds. It runs on a 6-watt brushless DC motor spinning up to 20000 rpm and delivers 15 cubic feet per minute of airflow. A semiconductor plate can cool its surface to 45°F for direct skin contact. The 100-speed button control and foldable 90-degree frame allow handheld, desktop or neck-worn use with the included lanyard.

Travelers and Event-Goers

This fan suits anyone who needs personal cooling away from power outlets during travel, sports events, concerts or hot commutes. The smart LED display shows exact battery level and current speed so you always know remaining runtime. Buyers who need continuous all-day cooling without recharging should look at larger devices, because the cooling plate draws significant power and the supplier notes runtime drops when it is active.

11-Hour Maximum Runtime

The single figure that decides suitability is the 11-hour battery life quoted at the lowest speed without the cooling plate engaged. At higher speeds or with the 45°F plate running, actual runtime will be shorter. The package includes a charging cable and manual but no wall adapter, so plan charging around your own USB power source.
