Product description

This compact 4-inch USB desk fan is the ideal personal cooling solution for anyone who wants quiet, adjustable airflow at their desk, bedside, or campsite. Powered by any standard 5V USB port — including power banks, laptops, and wall adapters — it requires no batteries and works wherever a USB connection is available.

With three fan speeds and three wind modes (natural, sleep, and prevailing wind), you can customize the airflow to suit your comfort level at any time of day. The 360° tilt adjustment lets you direct the breeze exactly where you need it, whether you're working, sleeping, or relaxing.

At just 5W power consumption, it's energy-efficient and quiet enough for use in bedrooms, offices, and small living spaces under 10 m². It also makes a handy companion for camping, travel, or any situation where a lightweight portable fan is needed.
