This compact electric fan is designed for practical use in spaces where noise and size matter, such as student dormitories or busy offices. Its 4-inch size fits neatly on a desk, and the brushless motor keeps operation quiet at a rated 45-50dB, so it won't disturb concentration or sleep. Available with either a direct plug or a lithium battery charging option, the fan provides flexible power for different setups. With three speed settings and a simple button operation, it offers straightforward airflow control for everyday comfort.

Features and Construction

The fan is built around practical components that support reliable airflow delivery in small spaces. Its plastic fan blades and brushless motor reduce noise while maintaining efficient rotation. The three-speed option allows users to choose between gentle breezes and stronger airflow depending on needs.

Material and Build

The fan uses a plastic blade material that keeps the unit lightweight and easy to move. The brushless motor type is designed for efficient energy use and quieter operation compared to brushed motors. The 3-blade configuration provides steady air movement for a fan of this size.

Size and Practical Fit

At 4 inches, this fan is small enough to sit on a desk, bedside table, or shelf without taking up much space. Its compact design makes it suitable for close-range personal cooling in dormitory rooms, office cubicles, or study areas. The USB power capability increases placement flexibility, allowing it to work with power banks, laptops, or wall adapters.

Uses and Placement

This fan suits environments where personal cooling is needed without disturbing others or cluttering surfaces. Its quiet operation and small footprint make it appropriate for shared or focused spaces.

Event or Professional Use

In office settings, the low noise level at 45-50dB helps maintain a quiet working environment while providing airflow. The USB compatibility allows it to run from a computer port or a standard charger, keeping desks uncluttered. The direct plug version offers a permanent power solution for desks near wall sockets.

Everyday Home Use

At home, the fan works well for personal use during sleep, reading, or working at a desk. The charging model with lithium battery can be moved between rooms without being tethered to a power outlet. Available in black, blue, pink, and white, it can match a variety of room colours.
