A desk fan is a small, portable device designed to circulate air in a specific area, typically used on a desk or table. These fans come in various sizes and styles, often featuring adjustable speeds and oscillation to enhance airflow. They are commonly powered by electricity, but some models may operate on batteries. Desk fans are popular for personal cooling, especially in warm environments or during hot weather. They can help improve comfort while working or studying by providing a gentle breeze. Many people also use them to improve air circulation in small rooms or offices, making them a practical addition to any workspace.
